NHAI OneTag FASTag Portability: How to Change Issuer Without Replacing Your Tag

Government service explainer | Original announcement: 17 September 2026. NHAI’s OneTag FASTag portability allows eligible drivers to change their tag’s issuing bank while retaining the sticker on the windscreen. Here is what the official announcement says, how the process works and what motorists should check before switching.

What NHAI announced

On 17 September 2026, the Ministry of Road Transport and Highways announced that OneTag FASTag portability was available through NHAI’s Rajmargyatra app. This is an explanation of that dated announcement, not a claim that a new change occurred today. The service allows eligible FASTag users to change their issuing bank without replacing the physical FASTag already attached to the vehicle. The existing tag identifier linked to the vehicle registration remains the same after a successful switch.

Why the service matters

Previously, switching an issuer could mean obtaining and affixing another tag. OneTag is intended to reduce repeated tag production and the inconvenience of replacing an otherwise usable sticker. It may also give drivers more choice when considering an issuer’s service, account experience or support. The government announcement does not promise that every application will be approved: eligibility and the new issuer’s verification requirements still apply.

How to request OneTag portability

1. Open the official Rajmargyatra mobile app and sign in. 2. Locate the OneTag portability service and enter the vehicle registration number to check eligibility. 3. Obtain the six-digit Mobile Verification Code sent by the existing issuing bank. 4. Authorise the request using that verification step. 5. Choose a new issuing bank and complete its customer verification and wallet onboarding. 6. Wait for successful completion before relying on the new issuer’s wallet for a journey. These steps follow the government’s published process; screen labels and processing times can vary.

What happens to the old FASTag wallet?

According to the September 2026 government release, the previous issuer closes the existing wallet after successful portability and refunds the available balance after applicable adjustments. The release does not guarantee an exact refund timeline. Keep account statements and transaction records until the closure and refund are reconciled. Contact the relevant issuing bank if a refund or account status needs clarification.

Can the same tag be ported again immediately?

No. The official announcement specifies a six-month cooling period before an interoperable FASTag can be ported again. Consider customer service, recharge options and account terms before selecting the new issuer. Portability is an issuer change, not a transfer of the FASTag to another vehicle.

Does OneTag change toll charges or annual-pass eligibility?

OneTag changes the issuing bank while retaining the tag; it is not a toll discount or an annual pass. Applicable toll fees still depend on the road, plaza and vehicle classification. Drivers researching pass benefits can read our FASTag annual pass versus local pass comparison and our guide to checking toll charges. The official Rajmargyatra portal also provides toll information and pass-related services.

Before starting: a practical checklist

Confirm that the FASTag is linked to the correct vehicle registration, that you can receive verification messages from the existing issuer, and that you have access to any identity details requested by the new issuer. Do not share verification codes with callers or unofficial intermediaries. Save confirmation messages and check your balance and transactions after the switch. If the app indicates that the vehicle is ineligible, follow its guidance rather than attempting to bypass the checks.

Where to get reliable help

Use the official Rajmargyatra portal for NHAI service information. The government also lists the national highway emergency helpline 1033 among the app’s services; that is not a substitute for contacting your issuer about banking or wallet issues.
