OneTag Launched for FASTag Users: Change Issuer Bank Without Replacing FASTag; What Happens to Existing Wallet?

OneTag Lets FASTag Users Change Their Issuer Bank

FASTag users now have a new option to change their issuer bank without going through the hassle of replacing the physical FASTag sticker on their vehicle.

The National Highway Authority of India (NHAI) has introduced OneTag, a FASTag portability facility that allows users to switch from their existing issuer bank to another participating issuer while retaining the FASTag already attached to the vehicle.

The facility has been launched through the Rajmargyatra mobile application and is designed to make FASTag issuer switching easier for motorists.

Previously, a customer wanting to move to another FASTag issuer generally had to close the existing tag and obtain a new one. Under OneTag, the physical tag can remain in place while the issuer associated with it changes.

What Is OneTag?

OneTag is a portability solution for the National Electronic Toll Collection (NETC) FASTag ecosystem.

Its main purpose is to allow a FASTag customer to change the bank providing FASTag services without having to remove and replace the physical FASTag sticker.

The existing FASTag ID linked to the vehicle registration number remains unchanged after successful portability.

This means the physical tag already attached to the windscreen can continue to be used even though the issuer bank changes.

The initiative is also intended to reduce repeated FASTag production, dispatch and reissuance costs and make the issuer-switching process more interoperable.

How Can FASTag Users Use OneTag?

The OneTag process is available through the Rajmargyatra app.

The process involves several steps:

1. Log in to the Rajmargyatra app.

2. Enter the vehicle registration number.

3. Check whether the FASTag is eligible for portability.

4. Receive a six-digit Mobile Verification Code (MVC) from the existing issuer bank.

5. Authorise the portability request.

6. Select the preferred new issuer bank.

7. Complete fresh customer verification and KYC with the new issuer.

8. Complete wallet onboarding with the new issuer.

9. Once portability is successful, continue using the existing physical FASTag.

The process is therefore designed to transfer the FASTag's issuer relationship rather than physically replacing the tag.

Is Fresh KYC Required for OneTag?

Yes. Fresh KYC is required.

This is an important point for FASTag users considering the new portability facility.

The existing issuer bank first verifies and authorises the customer's request. After that, the customer selects the new issuer bank and completes the required customer verification and KYC process with the new issuer.

The new bank then completes the wallet onboarding process.

Therefore, OneTag does not simply transfer the old wallet and customer relationship from one bank to another. The new issuer must complete its own onboarding and KYC requirements.

What Happens to Your Existing FASTag Wallet?

This is one of the most important changes for users.

Once portability is successfully completed, the previous issuer bank will close the existing FASTag wallet.

Any available balance in the old wallet will be refunded after applicable adjustments.

Therefore, the old wallet does not simply remain active alongside the new wallet.

The existing issuer is responsible for handling matters connected with the previous wallet, including applicable refunds and pending transactions, while the new issuer takes responsibility for the new wallet and FASTag services after successful onboarding.

Will You Need a New FASTag Sticker?

No, not under the OneTag portability process.

This is the central benefit of the new facility.

The FASTag ID associated with the vehicle registration number remains unchanged. Therefore, users can continue using the same physical FASTag attached to the vehicle.

This eliminates the need to remove the existing sticker and attach a newly issued FASTag merely because the customer wants to change the issuer bank.

What Happens to the Money in the Old Wallet?

The balance remaining in the old FASTag wallet does not simply disappear when the issuer is changed.

After successful portability, the previous issuer closes the existing wallet and refunds the available balance after applicable adjustments.

Users should therefore be aware that the old wallet balance and the new issuer's wallet are treated as separate parts of the portability process.

The previous issuer handles the old wallet and related refund or pending-transaction matters, while the new issuer handles the onboarding of the new wallet.

What Happens to Pending Transactions?

The existing issuer bank continues to handle matters relating to the old wallet, including pending transactions and refunds.

This means users should not assume that all old-wallet transactions disappear immediately when the portability process begins.

The previous issuer remains responsible for settling the relevant matters associated with the old wallet as part of the transition.

OneTag Has a Six-Month Cooling Period

FASTag users also need to know about a six-month cooling period.

After an interoperable FASTag has been ported, it cannot be ported again immediately. A cooling period of six months applies before the FASTag can undergo another portability process.

This means users should choose their new issuer carefully rather than expecting to switch banks frequently.

Why Has NHAI Introduced OneTag?

The OneTag initiative is intended to make the FASTag ecosystem more flexible for customers.

Before portability, switching issuers could involve closing an existing FASTag and obtaining another tag. This created additional administrative work and could involve the production, dispatch and replacement of physical tags.

OneTag allows the same physical tag to remain with the vehicle while changing the issuer bank.

NHAI has said the initiative is intended to improve customer choice, streamline the issuer-switching journey and reduce costs associated with repeated FASTag production and reissuance.

What Is FASTag and How Does It Work?

FASTag is an RFID-based electronic toll-payment system that allows toll charges to be collected electronically while a vehicle passes through a toll plaza.

The FASTag sticker is attached to the vehicle's windscreen and is linked to an account or wallet maintained through the issuer.

When the vehicle passes through a FASTag-enabled toll facility, the applicable toll amount is electronically deducted.

The system is intended to facilitate cashless toll payments and reduce waiting time and congestion at toll plazas.

FASTag Remains Widely Used Across India's Toll Network

FASTag is part of the NETC ecosystem operated through participating banks and payment infrastructure.

NPCI's latest available statistics show that 40 banks were live on NETC in July 2026, with more than 347 million transactions recorded during the month and transaction value of more than ₹7,142 crore.

The scale of the network means that changes to FASTag portability can affect a large number of vehicle owners.

What FASTag Users Should Check Before Porting

Before starting OneTag portability, users should make sure their existing FASTag and vehicle information are correctly mapped.

They should also check:

• Whether the FASTag is eligible for portability.

• Whether the registered mobile number is active.

• Whether they can receive the MVC from the existing issuer.

• Whether their vehicle registration details are correct.

• Whether the new issuer supports the required FASTag service.

• Whether fresh KYC documents are available.

• Whether there are pending transactions with the old issuer.

• The balance available in the existing wallet.

Users should also understand that the old wallet will be closed after successful portability and that its balance will be refunded after applicable adjustments.

What If You Do Not Want to Change Your FASTag Bank?

There is no requirement to use OneTag simply because the facility has been introduced.

Existing FASTag users who are satisfied with their current issuer can continue using their existing arrangement, subject to the applicable FASTag and issuer rules.

OneTag is essentially an additional portability option for customers who want to change their issuer without replacing the physical tag.

Why the New System Could Be Useful for Vehicle Owners

OneTag can be particularly relevant for FASTag users who are dissatisfied with their existing issuer's service, want to move to another bank or prefer a different issuer's wallet and customer-service arrangements.

The biggest practical advantage is that users do not have to remove the physical FASTag merely because they want to change the issuer.

This can make the transition simpler and reduce the need for repeated physical tag issuance.

Important Points About OneTag

Here are the key things FASTag users should remember:

1. You can change the issuer bank.
OneTag allows eligible users to move to another issuer.

2. You do not need to replace the physical tag.
The existing FASTag can remain attached to the vehicle.

3. Fresh KYC is required.
The new issuer will complete customer verification and wallet onboarding.

4. Your FASTag ID remains unchanged.
The existing FASTag ID linked to the vehicle registration number continues after successful portability.

5. The old wallet will be closed.
The previous issuer closes the existing wallet after the portability process.

6. The old balance is refundable.
The available balance is refunded after applicable adjustments.

7. Pending transactions are handled by the old issuer.

Bottom Line

The launch of OneTag changes the way FASTag users can switch issuer banks.

Instead of closing the existing FASTag and replacing the physical sticker, eligible users can now use the Rajmargyatra app to initiate portability and select a new issuer. The existing FASTag ID and physical tag remain unchanged after successful portability.

However, users will need to complete fresh KYC and wallet onboarding with the new issuer.

The old issuer will close the existing FASTag wallet and refund the available balance after applicable adjustments. Pending transactions and other matters related to the previous wallet will also be handled by the existing issuer.

Users should also remember the six-month cooling period before another portability request can be made.

Overall, OneTag separates the physical FASTag from the issuer relationship, giving users a way to change banks without having to replace the tag attached to their vehicle.
