FASTag Portability: OneTag Steps

FASTag portability is for changing the issuer of an existing tag. It is not the process for replacing a damaged sticker, correcting vehicle details or resolving a disputed toll debit.

The National Highways Authority of India (NHAI) says a successful OneTag move keeps the physical FASTag and its ID linked to the same vehicle registration number. It does not promise that every tag or bank pairing is eligible.

How to port a FASTag

The customer uses the Rajmargyatra app and follows the result shown for their vehicle:

1. Sign in and enter the vehicle registration number to check eligibility.
2. Enter the six-digit Mobile Verification Code (MVC) sent by the current issuer. The customer should enter this code themselves; do not keep it in counter notes.
3. Authorise the request and select the new issuer offered for that vehicle.
4. Complete the new issuer’s identity checks and wallet setup. Keep its acknowledgement.
5. Check the final confirmation and which account should receive future recharges.

These steps follow NHAI’s OneTag announcement. An eligibility result is only the start of the process; it is not proof that onboarding finished. Keep the last completed stage and reference if the app stops.

Check the chosen issuer’s conditions

Before collecting documents or payment, ask the selected issuer which vehicles, existing banks, documents and charges it accepts. For example, Federal Bank’s public customer instructions currently specify an active tag, an updated vehicle number, no active dispute and its own vehicle-class scope. Those are Federal Bank conditions, not rules for every issuer or evidence that SiOnline represents that bank.

Federal Bank also says its onboarding must finish within 72 hours of consent, otherwise a fresh request is needed. This is its onboarding window, not a promise that every port completes within 72 hours. Ask the chosen issuer about its own deadline.

What happens to the old FASTag balance?

The old balance does not simply move into the new wallet. NHAI says the previous issuer closes the old wallet after successful portability and refunds the available balance after applicable adjustments. The Ministry’s launch announcement assigns old-wallet refunds and pending transactions to the previous issuer. The new issuer handles its own onboarding and later services.

Keep the old wallet statement, any dispute reference and the new issuer’s acknowledgement. Confirm the new wallet’s usable balance and tag status before travel.

If the request is refused or gets stuck

A blocked tag needs the existing issuer’s help. IHMCL’s FASTag FAQ says the issuer can identify why a tag is blacklisted. Portability is not a way to bypass that status.

Can the tag be ported again?

NHAI states a six-month cooling period before repeat portability. Federal Bank’s customer instructions also describe a once-per-tag condition for its service. Do not promise that waiting six months alone makes every repeat move possible. Check the current app result and the chosen issuer’s rules.

If the customer has an Annual Pass or local pass, ask about that pass before approving a move. Keeping the sticker does not, by itself, confirm how the pass will work afterward.
