Digital services glossary.
Plain English.

Enrolment Identification Number

An Aadhaar Enrolment ID, or EID, identifies an enrolment interaction recorded through the Aadhaar process. UIDAI’s regulations define it as the enrolment identification number allocated at enrolment. It is different from the Aadhaar number issued after the applicable processing, and an acknowledgement does not by itself establish that Aadhaar has been generated.

Aadhaar Paperless Offline Know Your Customer

Aadhaar Paperless Offline e-KYC is a UIDAI-generated, digitally signed document used to share identity information for offline verification. The holder downloads an XML file and shares it through the permitted process. The receiving organisation verifies the signed data; simply opening the file or seeing a photograph does not complete that verification.

Aadhaar Payment Bridge System

The Aadhaar Payment Bridge System, or APBS, routes electronic benefit payments using Aadhaar as the payment address. NPCI’s mapping arrangement identifies the destination bank, which handles the credit to the linked account. APBS is a payment route; it does not decide whether a person qualifies for a government benefit.

Aadhaar in a Polyvinyl Chloride card format issued through UIDAI

An Aadhaar PVC card is the compact, durable card version of Aadhaar issued through UIDAI’s official ordering service. PVC stands for Polyvinyl Chloride, the card material. It represents the holder’s Aadhaar details in another format; ordering it does not create a new Aadhaar number, update identity information or make other valid Aadhaar formats obsolete.

Aadhaar Secure Quick Response Code

An Aadhaar Secure QR Code carries digitally signed identity data generated by UIDAI. It supports verification of information associated with an Aadhaar document through the appropriate tools. It is not a payment QR code, and displaying or decoding its contents is different from validating the signature and completing a service’s identity checks.

Update Request Number (URN) and Service Request Number (SRN)

URN means Update Request Number and SRN means Service Request Number in Aadhaar service processes. They identify requests rather than replacing the Aadhaar number. Which reference a person receives depends on the process used. Keep the actual acknowledgement and use the reference requested by UIDAI’s relevant status or support service.

Virtual ID

An Aadhaar Virtual ID, or VID, is a temporary, revocable identifier mapped to an Aadhaar number. UIDAI describes it as a random 16-digit number that can be used in place of the Aadhaar number for authentication or e-KYC. It is neither a new Aadhaar number nor the OTP used to approve a particular request.

Identity checks for the applicable booking route

Aadhaar-authenticated Tatkal booking refers to the Aadhaar-related identity checks described for the relevant Tatkal booking route. Profile authentication, an Aadhaar-based transaction OTP and an agent's appointment are separate matters. Completing one does not automatically establish the others.

Aadhaar Enabled Payment System

A payment system for Aadhaar-enabled banking transactions through participating bank arrangements.

A participant in bill payments

An NBBL-certified entity that provides a physical or digital customer interface for bill payments.

Customer booking-service charge

An agent service charge is a customer charge for the ticket-booking service described in IRCTC's agent policy. The policy defines it on a per-PNR or e-ticket basis, rather than per passenger. It is different from the railway fare, IRCTC's own charges and payment-handling charges.

Conditions for agent booking time

An agent Tatkal booking restriction is a condition limiting when an authorised agent may make the relevant booking. The Railways announcement of 11 June 2025 addresses an opening-period restriction separately from authentication requirements.

Advance Reservation Period

Advance Reservation Period, or ARP, means how far ahead a reserved railway journey can be booked under the applicable rule. It concerns the booking horizon, not the ticket’s confirmation status. Indian Railways’ general ARP was reduced to 60 days, excluding the journey date, from 1 November 2024; the official announcement also identifies exceptions.

Automatic Number Plate Recognition

ANPR stands for Automatic Number Plate Recognition. It uses cameras and image-processing software to read a vehicle’s registration plate. In announced Indian free-flow tolling deployments, ANPR works alongside FASTag to help identify vehicles. Reading the plate is an identification step; it does not by itself prove payment, grant an exemption or remove the need to follow toll rules.

System-led movement to a higher travel class under railway rules

Automatic upgradation is a railway arrangement under which an eligible reservation may be moved to a higher travel class through the applicable system process. Choosing an available upgrade option does not guarantee an upgrade. The passenger must check the class, coach and accommodation actually recorded for the journey.

Bharat Bill Payment System

BBPS stands for Bharat Bill Payment System. It is a common system for paying and collecting bills through participating apps, banks and service counters. Customers can use available payment modes, including UPI or cash at supported outlets. Bharat Connect is the name now used for this bill-payment ecosystem.

Theme-based tourist circuits

Bharat Gaurav refers to theme-based tourist-circuit trains under the Ministry of Railways' policy. The policy name is different from an ordinary train reservation and does not, by itself, identify the operator of every departure. Read the actual itinerary and package terms.

BHIM Aadhaar Pay

BHIM Aadhaar Pay enables a participating merchant to receive payment from a customer through Aadhaar authentication under the supported banking arrangement. It is a purchase-payment use case, not simply another name for withdrawing cash at an AEPS counter. The merchant’s acquiring-bank setup and the customer’s applicable account conditions matter.

The entity collecting a bill

The organisation or other entity connected to BBPS to collect its bill payments.

Biller Operating Unit

The bill-payment participant that connects billers to BBPS, directly or through a biller aggregator.

An authorised interruption of a railway journey under the applicable ticket rules

A break journey is an authorised stop during a railway journey, followed by continuation under the applicable ticket conditions. It is different from a train’s scheduled halt or simply deciding to leave a train and board another later. Whether it is permitted depends on the ticket, reservation and railway rules that apply to the journey.

IRCTC’s Buddhist tourism programme

The Buddhist Circuit Tourist Train is an IRCTC tourism programme built around places associated with the Buddha’s life. It is a tourist-circuit product, rather than simply a point-to-point railway ticket. To understand an offer, read the selected departure’s itinerary, category, inclusions and booking conditions; the programme’s name alone does not establish its current price or availability.

Central Know Your Customer

CKYC refers to the central recording of a customer’s Know Your Customer information in the Central KYC Records Registry. The registry stores and makes records available through the authorised financial-sector process. A KYC Identifier identifies the customer’s record; it is not a bank account number or automatic approval for a new service.

Retail-agent authorisation record

The Certificate of Authorisation is the record issued by the PSP to its retail agent for railway e-ticketing under the cited IRCTC agent rules. Those rules require the certificate to be displayed prominently at the outlet. It is different from a payment receipt or a generic shop-registration document.

A bundle of channels compared with individual channel selection

A channel bouquet is a group of television channels offered together as a bundle. A-la-carte means a channel is offered individually. These are ways of selecting programming, not descriptions of whether a recharge succeeded. The customer should compare the actual channel list and complete applicable account cost before choosing.

A disputed payment handled through the applicable payment-scheme process

A chargeback is a process through which a disputed payment is returned or challenged through the institutions and rules of the relevant payment scheme. In a card-payment context, the issuer and acquirer handle defined dispute rights and responses. It is different from a merchant voluntarily issuing a refund and does not guarantee that every complaint will succeed.

Preparing the passenger reservation chart

Chart preparation is the railway process of preparing the passenger reservation chart for a train. The chart brings together reservation and allocation information used for the journey. It is different from the date on which bookings open. When checking a ticket, read both the charting information and each passenger’s current status instead of assuming a chart label answers every question.

A railway ticket for an eligible itinerary beginning and ending at the same station

A Circular Journey Ticket is an Indian Railways ticket for an eligible multi-stop itinerary that begins and ends at the same station. It can be relevant to a pilgrimage or sightseeing journey. The route must meet railway conditions; having a circular ticket does not by itself confirm a seat or berth on every train involved.

Digital Signature Certificate

A Digital Signature Certificate, or DSC, is a digital certificate issued through a Certifying Authority. Class 3 identifies an assurance category in India's certificate framework. The certificate, the hardware token holding signing credentials and an IRCTC agent appointment are related to different questions.

Customer Operating Unit

The participant providing the customer-facing bill-payment interface, directly or through Agent Institutions.

Booking vacant railway accommodation after charting

Current booking is the railway facility for booking vacant accommodation after chart preparation. It concerns seats or berths available for a new reservation at that stage. It is different from checking the current status of an existing PNR, and it does not mean every train has accommodation available until departure.

Direct Benefit Transfer

Direct Benefit Transfer, or DBT, is the government’s approach to delivering scheme benefits directly to intended beneficiaries. For a cash benefit, the process includes transferring money through the applicable payment arrangement. DBT is not one universal subsidy, and the term does not establish that a particular person is eligible or has received a payment.

Electronic Aadhaar

e-Aadhaar is a password-protected electronic copy of Aadhaar digitally signed by UIDAI. It provides the Aadhaar document in downloadable electronic form. It is not a fresh Aadhaar enrolment, a different identity number or an e-PAN document. Downloading a copy also does not change the holder’s underlying Aadhaar information.

An electronic PAN document

The electronic form of a PAN document. An e-PAN document and the Instant e-PAN application service are different concepts.

Electronic railway reservation

A railway e-ticket is a reservation made electronically through the railway booking service. The reservation is the booking itself; the Electronic Reservation Slip, or ERS, presents its details. The PNR identifies the reservation record. A bank debit or payment receipt is a separate record and should not be treated as proof that the intended ticket was successfully booked.

Electronic Reservation Slip

ERS stands for Electronic Reservation Slip. IRCTC defines it as the prescribed slip containing reservation particulars and instructions. It is different from the reservation's PNR reference and from the agent's invoice or payment receipt.

Named package departure origin

“Ex-city” in a tour-package title identifies the departure origin named for that offer. For example, an official IRCTC brochure titled “Charismatic Kerala, Ex-Bhubaneswar” uses Bhubaneswar as the named starting point. The label does not, by itself, include travel from every customer's home to that origin.

An RFID tag for electronic toll payment

A vehicle tag that uses radio-frequency identification to make electronic toll payments through the participating network.

Independent and group travel arrangements

FIT and GIT describe different approaches to organising a trip. FIT is used for independent travel arrangements, while GIT commonly means Group Inclusive Tour: travel organised around a shared group itinerary. The labels help explain how a trip is planned. They do not, by themselves, establish every inclusion, the price, change rights or booking conditions.

Free-to-Air

A free-to-air, or FTA, television channel is one the broadcaster declares as free-to-air and for whose signal the distributor does not pay a fee to the broadcaster. That channel status is different from the total cost of a customer’s television connection. Distribution, equipment and other applicable account charges need separate consideration.

General Wait List

GNWL means General Wait List in the official railway status legend. It identifies the waiting-list category shown in the passenger's record. Read the complete current status rather than treating the code as a guarantee of confirmation.

A historical booking-product label

I-ticket is a legacy IRCTC product label found in older service material. It should not be used as another name for a printed e-ticket. A current e-ticket remains an electronic reservation even when its reservation slip is printed.

Immediate Payment Service

IMPS stands for Immediate Payment Service, an interbank electronic transfer service offered through participating institutions and operated by NPCI. It supports real-time transfers around the clock. IMPS names the payment service behind the transfer; it is not the same as a retailer’s account, a transfer reference or a guarantee that every attempted payment succeeds.

Indian Financial System Code

IFSC stands for Indian Financial System Code. It is an alphanumeric code identifying a bank branch participating in the relevant electronic payment system. In a transfer form, the IFSC identifies the branch, while the account number identifies the destination account. Neither is the transaction reference generated for the payment.

Internet Cafe Scheme

The Internet Cafe Scheme, or ICS, is an IRCTC agent-booking arrangement. In IRCTC's policy definition, registered retail agents of a principal provider serve customers through the IRCTC website or Rail Connect app. “Internet cafe” in this scheme name does not mean that every shop with an internet connection is already authorised.

An authorised railway booking agent

An agent who books railway tickets for customers through the authorised agent arrangement, rather than a personal user account.

Authorised booking interface

IRCTC agent login is access to the interface used under an authorised railway-agent arrangement. It is different from a personal-user login and from a generic retailer account used for other services. Opening a login page does not by itself establish that a particular agent ID is registered, active or entitled to perform every booking action.

IRCTC online-booking charge

An IRCTC convenience fee is an IRCTC charge associated with the online booking service, shown separately from the ticket fare. It should not be described as the shop agent's commission or confused with the agent's own permitted booking-service charge.

Cancellation-refund verification code

An IRCTC refund code refers, in the cited agent cancellation workflow, to an OTP associated with verification of a customer's cancellation refund. Its purpose is different from the OTP used to sign in to the agent account.

Tour packages and travel services

IRCTC Tourism covers travel products and packages offered through IRCTC's tourism services. A tour-package enquiry is different from an ordinary point-to-point railway reservation. The itinerary, inclusions, exclusions and product-specific conditions establish what a particular package offers.

Know Your Vehicle

Vehicle-verification requirements associated with FASTag. Check current applicability for the vehicle and issuer.

Aadhaar copy with part of its number concealed

Masked Aadhaar is an Aadhaar download option that conceals the first eight digits of the Aadhaar number and displays the last four. Other document information remains available. Masking reduces the exposure of the full number; it does not make the document anonymous or guarantee that every receiving service will accept that format.

Merchant Discount Rate

Merchant Discount Rate, or MDR, is a charge associated with a merchant accepting a payment under the applicable acquiring arrangement. It is commonly recovered from the merchant’s transaction proceeds. MDR is different from the merchant’s profit, a retailer’s service commission or a customer-facing service charge, and its treatment depends on the payment product and current rules.

A terminal for supported banking transactions

A device used in bank-led counter services. “Mini ATM” is also used commercially; check the actual device and programme capabilities.

Mobile Money Identifier

MMID stands for Mobile Money Identifier. It is a seven-digit identifier issued by a bank for an account linked to a mobile number, used with that number in a supported IMPS transfer method. It identifies the account in that method; it is not a password, an OTP or a requirement for every way of transferring money.

Mobile Number Portability

Mobile Number Portability, or MNP, lets a subscriber keep their mobile number when moving to another service provider under the applicable process. The number can remain familiar while the serving operator changes. A recharge retailer must therefore confirm the current operator rather than rely on the number’s prefix or the customer’s old recharge history.

Multi-Lane Free Flow

Multi-Lane Free Flow, or MLFF, is a toll-collection arrangement designed to let vehicles pass through a toll location without stopping at a physical barrier. Indian deployments combine identification technologies such as number-plate recognition with FASTag-based electronic payment. Removing the barrier changes how toll is collected; it does not remove the applicable toll.

Recharge services across operators

A retailer service for handling recharge requests across supported operators. A dedicated SIM is not the same thing as web or app access.

National Automated Clearing House

The National Automated Clearing House, or NACH, is an NPCI-operated system supporting large numbers of electronic payments and collections through participating institutions. NACH Credit is used for disbursements such as salaries or pensions, while NACH Debit supports authorised collections. A mandate and an actual successful payment are separate records.

National Electronic Funds Transfer

National Electronic Funds Transfer, or NEFT, is an electronic payment system owned and operated by the Reserve Bank of India. It transfers funds through participating banks using batch processing. The recipient’s account and bank-branch details identify the destination, while the transaction reference helps the banks identify an individual transfer.

National Financial Switch

NFS stands for National Financial Switch, an ATM network operated by NPCI that connects participating institutions for interoperable ATM services. It helps institutions exchange transaction messages and handle the associated network processes. NFS is not a customer’s bank account, an individual ATM or a guarantee that every ATM transaction will succeed.

National Train Enquiry System

The National Train Enquiry System, or NTES, provides railway information about train movement and services, including running status and expected arrivals or departures. It helps answer where a train is or when it is expected. It does not establish whether an individual passenger has a confirmed reservation or a valid ticket.

NPCI Bharat BillPay Limited

The authorised central unit operating BBPS. NBBL and an individual bill-payment retailer have different roles.

National Electronic Toll Collection

NETC stands for National Electronic Toll Collection. It is an interoperable payment system connecting participating institutions for electronic toll and related payments. FASTag is the tag used by a vehicle within that arrangement. Understanding the difference helps retailers separate tag, account and toll-transaction questions.

Network Capacity Fee

Network Capacity Fee, or NCF, is the amount charged for the television-distribution capacity subscribed to by a customer. TRAI’s definition separates it from the subscription price of pay channels or pay-channel bouquets. A customer’s DTH or cable bill can therefore involve distribution charges as well as the channels they have selected.

Aadhaar-to-bank mapping used by the Aadhaar Payment Bridge

The NPCI mapper is the mapping repository used to route Aadhaar Payment Bridge transactions to the appropriate destination bank. It associates Aadhaar information with the participating bank’s identifier. It is not a customer bank statement, a benefit-approval register or a complete database of the customer’s bank-account details.

Same-institution and different-institution transaction relationships

On-us and off-us describe the relationship between the institutions involved in a transaction. In RBI’s ATM example, using a bank’s card at that same bank’s ATM is on-us; using it at another bank’s ATM or a white-label ATM is off-us. The labels describe the relationship, not whether the transaction succeeded.

One Time Password authentication

OTP-based agent login uses a One Time Password as part of authenticating access to the agent account. IRCTC's agent policy describes a login OTP sent to the agent's registered mobile number. A login OTP is different from an OTP used for a passenger booking or a cancellation-refund workflow.

Permanent Account Number

PAN stands for Permanent Account Number. It is a unique ten-character alphanumeric identifier allotted by the Income Tax Department. The PAN number identifies the holder; a PAN card or e-PAN is a document bearing that number. An application acknowledgement, an agent’s portal ID and a PAN are different references, even when they appear in the same counter enquiry.

Payment in stages under product terms

Part-payment booking means paying a portion of a package price first and completing the remaining payment under the applicable conditions. For IRCTC Tourism, the published package terms distinguish this facility from the online booking route available to agents.

Passenger Reservation System

The Passenger Reservation System, or PRS, is the railway system supporting reserved-ticket transactions and reservation information. Customers encounter it through reservation counters and connected booking channels. PRS names the system, while a PNR identifies an individual reservation record. Access to a booking channel does not itself guarantee accommodation on a train.

Payment-handling charge

A payment gateway charge concerns handling the payment transaction. In IRCTC's integration policy, payment gateway charges are defined separately from the railway fare and agent service charge. The applicable amount and who levies it depend on the relevant payment arrangement and current terms.

Personal railway-booking account

A personal IRCTC user ID identifies a person's account for the personal-user service. It is different from an RSP ID in the authorised agent arrangement. IRCTC's agent rules prohibit using personal user IDs for commercial gain; a personal account should not be presented as a shortcut to an agent appointment.

A ticket permitting platform access under the applicable station conditions

A platform ticket allows a person who is not travelling to enter the railway platform under the station’s applicable conditions. It is typically relevant when meeting or seeing off a passenger. It is not a train journey ticket and does not authorise its holder to remain in a railway carriage or compartment.

Passenger Name Record

PNR stands for Passenger Name Record. In Indian Railways, it identifies the reservation record for a passenger or a group travelling together. The record brings journey and reservation details together. Having a PNR does not by itself mean that every passenger has a confirmed seat or berth.

Pooled Quota Wait List

PQWL means Pooled Quota Wait List in the official railway status legend. Keep the code with its displayed number when discussing the booking. A number in one waiting-list category should not be assumed to predict confirmation ahead of a number in a different category.

A distinct railway quota

Premium Tatkal is a railway quota label associated with dynamic pricing in the cited railway training material. It is different from a service provider's “Premium” registration plan. Paying for a plan with that name does not establish permission to book the quota.

Principal Service Provider

A Principal Service Provider, or PSP, is a firm registered with IRCTC under a ticketing scheme. In the ICS and B2B agent schemes, it provides e-ticketing through retail agents called RSPs. B2C describes a different customer-facing arrangement. Check the scheme as well as the company name when interpreting an offer.

Formerly NSDL e-Governance Infrastructure Limited

Protean eGov Technologies Limited is the organisation formerly named NSDL e-Governance Infrastructure Limited. Its official company information identifies the name change and PAN-related services. A historical “NSDL e-Gov” reference should be interpreted in that specific context, not treated as a statement that every organisation using NSDL is the same entity.

A PAN-agent service-account label

PSA ID is a label used in PAN-agent service discussions. The useful questions are which portal accepts the ID, who provides it and what service the account enables. It is not the applicant's PAN number or the reference for a particular PAN application.

Reservation Against Cancellation

RAC stands for Reservation Against Cancellation. It gives a railway passenger reserved sitting accommodation, while a separate sleeping berth is not confirmed. A berth may become available through cancellations or passengers not turning up. RAC is different from a waiting-list entry: check the passenger’s current status and allocation in the official reservation record.

Radio Frequency Identification

RFID stands for Radio Frequency Identification. It uses radio communication between a tag and a reader to identify the tagged item. In India’s FASTag context, the vehicle’s tag is read by toll equipment as part of electronic toll collection. The radio read is one part of the process; account status and payment processing remain separate considerations.

Reservation-category labels

Railway quota codes identify reservation categories. They are different from travel-class codes and from a passenger's booking status. For example, a quota label, an accommodation class and a waiting-list entry can describe different fields in the same reservation.

Rolling Deposit System

RDS means Rolling Deposit System in IRCTC’s agent-integration policy. It is a funding arrangement in which IRCTC maintains an advance-deposit account in a Principal Service Provider’s name for railway ticket bookings. The principal’s RDS account and a retailer’s balance with a service platform are different records; the same balance label should not be assumed to describe both.

Real Time Gross Settlement

Real Time Gross Settlement, or RTGS, is a system in which funds-transfer instructions are settled individually and in real time, without netting them against other instructions. In India, settlement takes place in RBI’s books. RTGS is primarily for large-value transfers; the bank’s customer channel and account conditions still apply.

A representative role in a PAN application

A representative assessee is a person acting on an applicant’s behalf where the applicable PAN requirements provide for representation. The term identifies a role in the application. It does not automatically describe the shop operator helping with the form, and it should not be confused with access to another person’s e-filing account.

Retail Service Provider

RSP means Retail Service Provider in IRCTC's integration policy. It is the retail agent registered for customer e-ticket bookings through a Principal Service Provider. The PSP registers the retail provider, while IRCTC issues the RSP ID under the cited agent rules.

Railway station accommodation

A railway retiring room is accommodation available at selected railway stations for eligible bookings under the applicable service rules. IRCTC’s official information describes single, double and dormitory options, with air-conditioned and non-air-conditioned categories where available. A train reservation and a retiring-room reservation are separate records; having a ticket does not mean a room has also been booked.

Retrieval Reference Number

A Retrieval Reference Number, or RRN, helps the participating payment institutions identify and retrieve a transaction record. Customers may encounter it in card or UPI payment information. The exact display label depends on the service, so use the reference shown for the actual payment rather than assuming every receipt number is an RRN.

Remote Location Wait List

RLWL means Remote Location Wait List in the official railway enquiry. It names a waiting-list category; “remote” is not a statement that the reservation is invalid. Check the intended journey and passenger's current status.

RuPay card-payment network

RuPay is a card-payment network developed by NPCI. A participating institution issues a card using the network, while that institution maintains the customer’s card or account relationship. The RuPay name identifies the network; it does not mean every card has the same account type, benefits, charges or acceptance conditions.

A period ticket for repeated travel on a specified railway route

A railway season ticket is a ticket for repeated journeys on a specified route during its stated validity period. It is commonly associated with regular commuting. The passenger must still follow the route, class, train and identification conditions that apply; holding a season ticket does not create a reserved seat or permission to use every train.

Special Tariff Voucher

A Special Tariff Voucher, or STV, changes specified voice, SMS or data benefits under a mobile subscriber’s applicable tariff plan without adding monetary value to the prepaid balance. Its benefits and validity depend on the voucher offered. An STV should not be confused with a talktime top-up or assumed to extend every aspect of the connection’s validity.

Standardisation Testing and Quality Certification

STQC stands for Standardisation Testing and Quality Certification. In the biometric-device context, STQC’s certification scheme assesses equipment against the applicable requirements, including UIDAI specifications. Certification concerns the product and its defined scope; it is not a bank appointment, an agent licence or a guarantee that the device works with every service platform.

Monetary calling balance and the period a recharge benefit lasts

Talktime describes monetary value available for chargeable calling or other permitted usage under a mobile plan. Recharge validity describes the period for which specified service or benefits remain usable. Adding talktime and extending validity are different outcomes; the customer must read what the chosen operator’s voucher actually provides.

A railway reservation quota

Tatkal is a railway reservation quota with its own booking conditions and charges. It is not a promise that accommodation will be available or confirmed. The booking route and user role matter: personal-user conditions and authorised-agent restrictions should not be treated as identical.

Restricted booking-automation tools

“Tatkal robot” is a label used for booking-automation tools or facilities promoted as providing an advantage in ticket booking. IRCTC's agent policy expressly identifies restricted automation and unfair technical advantages. An advertisement saying a tool is fast or agent-friendly is not evidence that IRCTC permits its use.

Tatkal Quota Waitlist

TQWL means Tatkal Quota Waitlist in the official railway status legend. The Tatkal label does not itself establish that accommodation is confirmed. Read the actual passenger status and relevant railway instructions.

Railway accommodation abbreviations

Train class codes identify the accommodation category selected for a railway journey. For example, 3A means AC 3-tier, CC means AC Chair Car and SL means Sleeper. The class is separate from the reservation quota, the passenger’s CNF/RAC/WL status, and the coach or seat number. Check each field when reading a ticket.

Unreserved Ticketing System

UTS stands for Unreserved Ticketing System, the Indian Railways system associated with unreserved travel ticketing. An unreserved ticket and a reserved seat or berth are different things. A digital ticket can still be unreserved, so the customer should read the ticket category and conditions rather than infer a seat reservation from the screen or payment receipt.

UPI payment options designed for feature-phone users

UPI 123PAY refers to UPI payment options designed to extend access to feature-phone users, including methods that do not require a smartphone internet connection. The available method depends on the participating provider and supported phone or service. It remains a payment process with enrolment and authentication requirements, not permission to transfer money without checks.

UPI ATM / Interoperable Cardless Cash Withdrawal

UPI ATM refers to supported ATM services that use UPI for customer authorisation. For cash withdrawal, the relevant facility is Interoperable Cardless Cash Withdrawal, or ICCW: a customer uses a supported UPI app at an enabled ATM instead of presenting a physical card. Availability depends on the participating bank, app and machine.

Unified Payments Interface ID / Virtual Payment Address

A UPI ID is a payment address used within the Unified Payments Interface. It is also called a Virtual Payment Address, or VPA. The address identifies a payment destination through the participating service. It is different from the secret UPI PIN used for authorisation and from the reference created for an individual payment.

UPI Lite small-value payment functionality

UPI Lite is a small-value payment feature that uses a Lite balance within a supported payment application. Eligible payments can be made without entering a UPI PIN for each payment. Loading that balance, spending it and receiving a refund are separate events, and the current app and bank conditions determine the available functionality.

Unified Payments Interface Personal Identification Number

A UPI PIN is a secret code used to authorise supported actions in a UPI payment application. It is different from a UPI payment address, a phone-unlock code or an OTP. Read the action shown on screen before entering it; entering a PIN is not a routine requirement for simply receiving money into an account.

PAN Service Agent in the UTIITSL channel

SiOnline uses UTI PSA to describe PAN Service Agent access in the UTIITSL service channel. The assisting shop, the application-service organisation and the Income Tax Department have different roles. A local counter's assistance does not make that counter the tax authority or guarantee PAN allotment.

UTI Infrastructure Technology and Services Limited

UTIITSL stands for UTI Infrastructure Technology and Services Limited. Its official PAN portal provides application-related services and identifies the organisation's offices. UTIITSL, a PAN-service agent and SiOnline are different organisations or roles; the terms should not be used interchangeably.

Unique Transaction Reference

UTR stands for Unique Transaction Reference. It identifies a bank-transfer transaction and can help a bank trace the payment using details such as its date and amount. A reference identifies the transaction being discussed; the actual status and receiving-side record must still be checked to establish what happened.

Alternate Train Accommodation Scheme

VIKALP is Indian Railways’ alternate-train accommodation scheme. It lets a waitlisted passenger opt to be considered for accommodation on another train. Selecting the option does not confirm a berth: allotment depends on availability and the scheme’s conditions. The passenger must check the resulting reservation before deciding which train to board.

WL and railway waiting-list categories

A railway waiting-list status means a seat or berth has not been allotted to the passenger in that status. WL is the abbreviation used in the official enquiry. Codes such as GNWL or TQWL identify different waiting-list categories. Read the current passenger status before explaining a booking; a queue number is not a promise that accommodation will become available.

Adding funds to a retailer account

Funding a service account through its supported process. Check the bank transfer and the platform balance as separate records.

SiOnline’s published PAN-application funding model

A wallet-based PSA ID, in SiOnline's published PAN-service explanation, uses a funded service-account balance for application activity rather than requiring the retailer to buy PAN coupons. This describes SiOnline's stated workflow; it should not be generalised into the architecture of every PAN provider.
