You have agreed a price, the papers are signed and the seller hands you the keys. There is a small sticker on the windscreen that nobody mentions. That sticker is the seller's FASTag, and it is linked to the seller's account, not to you. Until the seller closes it, the FASTag network still treats it as the tag for that registration number. Your tolls go on the seller's account, or bounce when their balance runs out. And when you walk into a bank to get a tag of your own, you may be told the vehicle already has one. This guide explains why that happens, what the 2026 rule changes mean for a used car, and the simple order of steps that gets the old tag closed and your new one working.
Why the Old Tag Does Not Change Owners
A FASTag is a small radio tag that pays tolls automatically when the car passes a plaza. Behind the tag there is a prepaid account or wallet held by a person, opened with a bank that issues FASTags. The tag is linked to the car's registration number, and the account is linked to the person who bought it. When the car is sold, the registration number moves to the new owner. The account does not. It still belongs to the seller.
That is why a FASTag cannot simply be "transferred" with the car. Issuer guides are clear on this point: the previous owner closes their FASTag account, and the new owner applies for a new tag in their own name. Any balance left in the old account goes back to the seller, which is one more reason the seller has to be the one who closes it.
Plain meaning of the words used here: issuing bank is the bank that sold the tag and holds the account behind it. Active means the FASTag network will accept the tag at a toll plaza. Blocked or hotlisted means the tag has been stopped, often for a low balance, a KYC gap or a duplicate tag. Closed means the account has been shut and the tag no longer works. KYV means Know Your Vehicle, a check that the tag matches the vehicle it is fitted to.
One Vehicle, One FASTag: Why the Bank Says No
In January 2024, NHAI announced its "One Vehicle, One FASTag" rule. The aim was to stop people using one tag on several vehicles, or having several tags for one vehicle. Under the rule, only the latest FASTag account for a vehicle remains active, and earlier tags are deactivated or blacklisted. NHAI also asked users to discard older tags through their banks.
For a used car buyer, this has a practical effect. If the seller's tag is still active on the registration number, banks generally will not issue you a second tag for the same vehicle. You can be stuck at the counter, or on an online form, with the car in your driveway and no way to get your own tag. The fix is not with your bank. It is with the seller's bank, and only the seller, as the account holder, can normally ask it to close the tag.
The 2026 change: the bank checks VAHAN first
On 1 January 2026, NHAI announced that it was discontinuing the Know Your Vehicle process for cars, jeeps and vans on all new FASTags issued from 1 February 2026. For existing car tags, KYV is no longer a routine requirement. NHAI said it will be needed only where a complaint is received, for example about a loose tag, wrong issue of a tag or misuse.
The same announcement moved the checking to the start. A new FASTag can now be activated only after the bank has validated the vehicle's details against the VAHAN database. The old option of checking after activation has been dropped. Where a vehicle's details are not available in VAHAN, the bank must check the Registration Certificate before activation, with full accountability. Tags sold online are covered by the same rule.
This is good news for a buyer in one way: once your tag is issued, you should not be chased for repeat checks later. But it also means the bank's system is reading the registration record before it will switch your tag on. Keep the RC and your own ID ready when you apply. If the RC transfer to your name is still in progress, ask the bank what it will accept before you apply, because practice can differ between banks.
What Happens at the Toll Plaza
If the seller's tag stays active, two things can happen. While their account has money, every toll you cross is charged to the seller. That is not a favour to you. It is a dispute waiting to happen, and the seller may block the tag the moment they notice. Once the tag is blocked or the balance runs dry, the car arrives at the plaza without a valid, functional FASTag.
The cost of that is now set out in the rules. The government amended the National Highways Fee (Determination of Rates and Collection) Rules, 2008, with effect from 15 November 2025. A vehicle that enters a national highway fee plaza without a valid, functional FASTag is charged twice the fee if it pays in cash, or 1.25 times the fee if it pays by UPI. On a Rs. 100 toll, that is Rs. 200 in cash or Rs. 125 by UPI.
The road transport ministry has since discontinued cash payments at national highway toll plazas from 10 April 2026, as widely reported at the time. In practice, that leaves UPI at 1.25 times the fee as the fallback for a car without a working tag on a national highway. A single crossing at a 25 per cent premium is small. A daily commute through a national highway plaza outside Delhi, Bengaluru or Hyderabad at that premium is not.
A tag on the glass is not proof of a working tag. The sticker looks the same whether the account behind it is active, blocked or closed. The only way to know is to check the status against the registration number, which reads what the FASTag network holds for that vehicle right now.
Read the Status Check: Three Answers, Three Next Steps
VahanBazaar's FASTag Status Check reads the registration number against the FASTag network and returns one of three answers. It shows the status exactly as the network returned it, the issuing bank, and the last four characters of the tag ID, so you can match it to the sticker on the windscreen. It does not show the balance, and it never shows the account holder's name, phone number or address. The result is as at the lookup time, with the date and time printed on the report.
| What the Check Shows | What It Means at Hand-Over | What to Do |
|---|---|---|
| FASTag active | A tag is still linked to the number and works. If you are buying, it is almost certainly the seller's | Match the last four characters to the sticker. Ask the seller to close it with the named bank on the day of sale |
| Found, not active | A tag is linked but blocked, hotlisted or closed | If closed, you can apply for your own tag. If blocked or hotlisted, the seller contacts the named bank to close it |
| No FASTag found | The network holds no tag for this number | Confirm the number is typed correctly, ask whether a tag was ever fitted, then apply for your own |
The bank name is the useful part for the seller. Many owners bought their tag years ago, or had it fitted by a dealer at delivery, and cannot remember which bank it came from. Without the bank, they cannot close it. With it, the closure is one call or one form. If the tag ID's last four characters do not match the sticker on the glass, ask why. It may mean a newer tag was fitted somewhere along the way, which is exactly the kind of untidy record that causes a tag to be blacklisted later. Our report on FASTags blacklisted for a wrong registration number covers that problem in detail.

The Hand-Over Checklist: Who Does What
Most FASTag trouble on a used car comes from a hand-over where nobody owned the job. The simplest fix is to agree, before money moves, who does each step and when. Here is the split that works for most private sales in Delhi, Mumbai, Chennai, Hyderabad or anywhere else.
| Step | Who | When |
|---|---|---|
| Check FASTag status by number | Buyer | Before paying the token amount |
| Tell the buyer which bank issued the tag | Seller | At the first meeting |
| Request closure of the old tag | Seller (account holder) | On the day of sale |
| Remove the old sticker from the glass | Seller, with the buyer present | At hand-over |
| Re-check status shows closed or no tag | Buyer | Before applying for a new tag |
| Apply for a new tag in own name | Buyer | After closure is confirmed |
Steps for the seller
- Find the issuing bank. It is often printed on the sticker. If it is worn off, the status check names it.
- Request closure, not just a block. Banks usually take closure requests through customer care, the bank's app or a written form. A typical form asks for the tag, the reason ("vehicle sold"), the registration number, ID proof and an account for the balance refund. Process details vary by bank.
- Ask for written confirmation. Keep the closure reference or email. If a toll is charged after the sale date, this is your proof.
- Peel off the sticker. Most FASTag stickers tear when removed, which stops the old tag being reused on another car.
Steps for the buyer
- Check before you pay. Run the status check on the registration number so you know whether there is an old tag to deal with.
- Make closure part of the deal. Write it into the sale note: the seller will request closure of the FASTag on the day of sale and share the confirmation.
- Re-check after closure. The status should show closed, or no tag found. Only then apply for your own tag.
- Apply with your RC and ID ready. Since February 2026 the bank validates the vehicle against the VAHAN database before activating a new car tag.
If the seller cannot be reached. This is the hard case, and there is no single published rule for it. Call the issuing bank named on the status report, explain that you have bought the vehicle, and ask what it needs from you. Keep copies of the sale papers and your RC transfer application. Expect it to take longer than a seller-led closure, which is why the closure belongs in the deal, not after it.
The Annual Pass Does Not Come With the Car
Some sellers will mention that their tag has an Annual Pass on it, as if it adds value to the car. Do not count on it. NHAI revised the FASTag Annual Pass fee from Rs. 3,000 to Rs. 3,075 for FY 2026-27, effective 1 April 2026. The pass covers private, non-commercial cars, jeeps and vans at national highway and national expressway fee plazas for one year or 200 trips, whichever comes first.
NHAI's own FAQ describes the pass as non-transferable and valid only for the vehicle on which the FASTag is affixed and registered. The pass sits on the seller's tag, and the tag sits on the seller's account. It is not yours to use. Once the old tag is closed and your own tag is active, you can buy your own pass through NHAI's official channels. For more on how the pass interacts with a used car's toll record, read our guide to the Rs. 3,075 FASTag pass and the used car check.
What This Means for Buyers and Sellers
For buyers, the FASTag is one more item on the hand-over list, and one of the cheapest to check. A status check takes seconds and tells you whether there is a tag to close and which bank holds it. That turns a vague "please close your FASTag" into a specific request the seller can act on the same day. It also protects you from the worst outcome, which is driving off with a car that has a working tag you do not control, and then being stopped at a plaza when the seller blocks it.
The FASTag is not the whole picture, though. A clean tag tells you nothing about the RC, the insurance, the loan status or pending challans. Run the Used Car History Check for the full RC record and pending challans in one report, and read our explainer on Form 29 and Form 30 so the ownership transfer itself does not get left hanging. Shortlisted a car on VahanBazaar's used car pages? Ask the seller for the registration number in writing and run these checks before you travel to see it.
For sellers, closing the tag is self-protection. While it stays open, your account pays for someone else's journeys, and any dispute about those tolls lands with you. Closing it on the day of sale, with written confirmation, ends that risk. If you are selling, a Verified Listing for Rs. 99 shows buyers from day one that the registration number has been checked against the VAHAN database, with a green Verified badge and no commission on the sale.

Frequently Asked Questions
You should not. The tag on the windscreen is linked to the seller's account, so every toll you cross is charged to the seller. If their balance runs out or they block the tag, you are stopped at the plaza. A FASTag account cannot simply be handed to a new owner. The seller closes their tag with the issuing bank, and you take a new tag in your own name.
The most common reason is that the old owner's tag is still linked to the registration number. Under NHAI's One Vehicle, One FASTag rule, only one tag per vehicle stays active, and banks generally will not issue a new one while an older tag is live on the same number. Ask the seller to close their tag with the bank that issued it, then apply again.
Under the National Highways fee rules amended in 2025, a vehicle without a valid, functional FASTag pays twice the fee in cash or 1.25 times the fee by UPI. Cash has since been discontinued at national highway fee plazas from 10 April 2026, as reported, so UPI at 1.25 times is the usual fallback. On a Rs. 100 toll that means Rs. 125 instead of Rs. 100.
Do not count on it. NHAI's FAQ describes the Annual Pass as non-transferable and valid only for the vehicle on which the FASTag is affixed and registered. The pass sits on the seller's tag and account. Once you have your own tag, you can buy your own pass, which costs Rs. 3,075 for FY 2026-27 and covers one year or 200 trips, whichever comes first.
Run the registration number on VahanBazaar's FASTag Status Check for Rs. 49. It shows whether a FASTag is linked to that number, whether the FASTag network reports it as active, the issuing bank, and the last four characters of the tag ID. It does not show the balance. The result is as at the lookup time.
