If you run a counter that sells FASTags, it’s easy to think of yourself as the one in charge. The customer pays you, you stick the tag on, and everyone goes home happy. But the rules say something different. A FASTag point of sale (PoS) works for the bank that issues the tag, and what you’re allowed to do depends on what that bank has authorised.

That’s good to know early. It explains why you can’t fix a wrong vehicle number at your desk, why a fitted sticker isn’t the same as an active tag, and why a charge shouldn’t be a surprise to the customer.

What does a PoS actually do?

NPCI’s NETC Procedural Guidelines v2.1, section 4.2.1.1, checked on 18 October 2026, name the main functions of a point of sale. They are user registration (which includes issuance, fixing the tag and Mapper registration) and top-up. The same section lets an issuer tie up with several agents as customer touch points. These agents issue tags on the issuer’s behalf, and the issuer makes the venue agreements.

So before you take any customer’s work, work out which part your appointment covers. Is it taking a new application? Fixing a tag? Helping with a recharge? Or only passing a correction request on to the bank? Having a login, or having stock on the shelf, doesn’t mean you’re allowed to do everything on a FASTag account.

A simple habit helps. Keep a one-page scope sheet. For each service, write down whether you do it yourself, whether you send information to the bank for action, or whether you send the customer elsewhere. Ask your programme contact to confirm anything you’re unsure about. And show the sheet to anyone new at your counter, so a customer doesn’t get a different answer depending on who is standing there.

Who authorises you, and who checks you?

NPCI’s onboarding guidelines, A(ii) to A(iv), checked on 18 October 2026, require tags to be sold through issuer-authorised PoS agents. They also require detailed KYC of new and existing agents, and agreements between the issuer and the places that host PoS outlets. As the business owner, you should be able to say which bank authorised you.

Can a customer check your appointment? Ask how they would do it. If a third party introduced the programme to you, ask for confirmation of its role through the bank’s own channel. A signboard, a brochure or a portal account isn’t proof of a bank appointment. And if you move premises, or someone new starts operating the account, ask the programme how it wants that handled. Don’t stretch an existing arrangement to a new location on your own assumption.

Why can’t you change a vehicle number?

NPCI’s onboarding guidelines, A(xii), reopened on 18 October 2026, say a PoS agent shall not be allowed to update or modify the vehicle registration number of any vehicle. The NETC Procedural Guidelines v2.1, section 4.1.1 B(iii) and B(iv) add that an agent cannot change FASTag data, and they put the correctness of the entered data and uploaded documents with the issuer.

So if a customer spots a wrong number, here’s what to do. Stop the request. Compare what was entered with the customer’s documents, without changing anything. Write down what looks wrong and send it to the issuer. Ask for an acknowledgement and for the authorised way to correct it. What you shouldn’t do is open a fresh application to hide the mistake.

What does “validation before activation” mean?

IHMCL Policy Circular 746, dated 30 December 2025, section 5A, checked visually on 18 October 2026, requires vehicle validation before activation from 1 February 2026. It ends the earlier T+3 window, when validation against VAHAN could happen after activation. If a vehicle’s details aren’t in VAHAN, the issuer must validate the RC before activation.

In plain words: a tag isn’t ready for toll use just because the customer paid or the sticker is on the glass. If the bank hasn’t finished validating, say so. Tell the customer the case is waiting for the bank’s validation. Give them the case reference and the last stage that was completed. Don’t guess how long it will take. If the bank’s application acknowledgement and its activation confirmation are two different messages, keep them apart in your head and in your notes.

How far does the car KYV exception go?

Circular 746, section 5B, checked on 18 October 2026, discontinues KYV for new VC-4 Car/Jeep/Van issuance from 1 February 2026, while keeping validation before activation. For older VC-4 tags, KYV is triggered only by a complaint. Section 5B(c) keeps KYV for other vehicle classes under the applicable NPCI guidelines.

That means two questions before you ask for any photos: what is the vehicle class, and is this a new issuance or a complaint case? Don’t use an old car-photo checklist for every new car. And don’t tell a truck owner that the car exemption removes the KYV that applies to his vehicle.

For the classes and cases where document requirements do apply, NETC guidelines v2.1, section 4.1.1 B(i) and B(ii) describe an RC, clear images of the vehicle and the tag, and legible, verifiable records. Digital RC copies are allowed through Parivahan or DigiLocker. Masked data shouldn’t be uploaded. Check that the numbers are readable and that the vehicle in the photo is the one in the request. Never edit a number into an image, and never reuse a photo from another customer’s vehicle.

Who handles fixing, Mapper registration and a wrong class?

NPCI’s onboarding guidelines, A(vi), checked on 18 October 2026, say the issuer or an authorised PoS agent has to see that the tag is fixed on the windscreen as the guidelines require. So the sale isn’t finished when the sticker leaves your stock. Tell customers the vehicle must be present, and keep the fitting separate from the activation status. Fitted does not mean active.

NETC guidelines v2.1, section 4.1.1 B(ix), reopened on 18 October 2026, put registration in the NETC Mapper with the issuer. They prohibit transactions on an unregistered tag and require the issuer to start registration again if it fails. Under section 4.1.1 B(xi), the issuer must verify and map the correct vehicle class. Toll plazas can report cases of the wrong class, and the issuer must arrange the Mapper class update.

So never offer to change a class at your desk. For a class complaint, note the vehicle documents, the class shown in the record and what the customer saw happen. Then ask the issuer to confirm the right mapping.

What must you tell the customer about charges?

NPCI’s onboarding guidelines, A(x) and A(xi), reopened on 18 October 2026, require charges to be disclosed clearly before the tag is issued, and shown on the issuer’s website or portal. Printed customer information with charges, the issuer’s care number and its email address should be available with PoS agents to hand over.

Explain what the amount is made of before you ask the customer to pay. If the amount you want to charge doesn’t match the material the bank gave you, ask the bank. Don’t invent a local charge to cover the gap.

FASTag agent fees and commission are not published here. SiOnline shares the figures for your case on enquiry. Ask for them in writing before you pay anything. And keep two things separate: what the customer pays, and what passes between you and the programme under its terms. The FASTag commercial-terms questions will help you ask about the second one.

What do you do with faulty or doubtful stock?

The NETC guidelines, failure scenarios before section 4.2.1.1, printed page 72, checked on 18 October 2026, cover tags that were wrongly personalised, tags lost during distribution and tags that don’t meet the size or format required. Wrongly personalised or nonconforming tags are to be destroyed, and tags lost in distribution are to be blocked and hotlisted. The issuer is responsible for that process.

For you, it comes down to a few habits. If an item looks doubtful, keep it away from the stock you issue to customers. Report it through the programme’s stock-control route. Don’t change its printed or encoded identity, and don’t put it back in circulation because it looks fine. If your stock record doesn’t match what’s on the shelf, stop issuing the affected item and ask for a check before you hand out another tag.

A made-up example

Say a customer’s RC is readable, but the bank’s validation comes back with a mismatch. The tempting move is to change a detail so the screen turns green. Don’t. Treat the mismatch as the question. Ask the issuer what evidence it needs. Tell the customer what is still unresolved. This is only an example to show the order of thinking. It isn’t a report of a real customer.

When something doesn’t fit the routine

Use the same four steps every time: find the check that failed, stop that action, keep the reference, and ask the issuer for the permitted next step. Tell the customer what’s still open. And don’t quietly switch to another vehicle number, another class or another account to finish the sale.

For operator permissions, use the FASTag agent login guidance. For an existing SiOnline enquiry, use SiOnline support. Keep passwords and customer authentication codes out of case notes and public messages.

A short checklist before your first customer

Do you know which bank authorised your outlet, and can you show how to verify it?
Have you written down which services you perform, which you pass to the bank and which you send elsewhere?
Do you have the printed charge information, with the bank’s care number and email address, ready to hand over?
Do you know how a wrong vehicle number gets corrected, and who to ask?
Is your stock record the same as what is physically on the shelf?
Have you asked for the programme’s commercial terms in writing?

If any answer is no, fix that first. It’s much easier than explaining a problem to a customer later.

Questions about PoS permissions

Does an outlet’s business type decide whether it’s authorised?

No. Ask the issuer about your actual outlet and the services you plan to offer. A named venue example in a bank’s guideline isn’t an acceptance of your shop. Keep the appointment scope, and the way to verify it, ready before you tell customers your counter can issue a particular bank’s tags.

Can the operator correct a registration number?

No. Send the request to the issuer’s authorised correction process, keep the original application reference and ask for an acknowledgement.

Can a customer use the tag while validation is pending?

Wait for the bank’s activation confirmation first. Fitting, payment and submitting the application are different from activation.

Confirm the scope of your proposed PoS

Describe your outlet and the work you want to do in the FASTag agent enquiry, and ask for the programme scope, operating instructions and commercial terms for that counter.
