Can I Have Two FASTags for One Car? One Vehicle, One FASTag Explained

We’ve talked about electronic toll collection (and FASTag) a fair amount here, but at least from a customer perspective, there’s always more to talk about (definitely a good thing). More so when you consider just how critical electronic toll collection has become to India’s overall highway ecosystem.

After all, there are more than 7 crore FASTags issued across India. Because of that, the question keeps on surfacing: Can’t I have 2 FASTag for one car? Many vehicle owners often wonder if they can keep multiple tags with them for possession. Or think about things like: “Can one tag be used for more than one vehicle?”

So that’s the answer? Chances are that if you’ve clicked on this blog, you already may have an idea. This blog explains the ‘One Vehicle, One FASTag’ rule; explores why it exists; and elaborates on what you should do if you want to replace a damaged tag.

FASTag is an RFID-based sticker linked to your vehicle’s Registration Certificate (RC). Once affixed on the windshield, it automatically deducts tolls from your prepaid account.

The One Vehicle, One FASTag rule was enforced by NHAI and the Indian Highways Management Company Ltd. (IHMCL) to:

• Prevent misuse of tags across multiple vehicles.

• Improve throughput at toll plazas.

• Ensure KYC compliance as per RBI norms.

• Avoid technical errors like double deductions at plazas.

For example, before this rule, some users attempted to keep multiple FASTags for the same car under different wallets to “game” cashback schemes or avoid low balance alerts. Others even tried to shift one FASTag between two cars to save the cost of buying another. These practices created chaos at toll lanes and financial mismatches in the NETC system.

Hence, the One Vehicle, One FASTag framework was introduced to bring order and efficiency.

The official rule states:

• Only one active FASTag can be linked to a single vehicle.

• Any attempt to keep two or more FASTags linked to the same registration number will result in automatic deactivation of older tags.

• NHAI and banks enforce this by mapping each tag to the vehicle’s RC and class of vehicle.

This policy was rolled out in 2021 and is now fully enforced. Under RBI norms, KYC completion is mandatory, ensuring that each FASTag is tied clearly to the correct owner and vehicle.

The short answer? No.

If you attempt to use two FASTags for the same car:

• Only the latest issued FASTag will remain active.

• The previous one will be automatically deactivated by the NETC system.

• In rare cases, both may be read at plazas, causing double deductions.

Risks of having two FASTags on one car include:

• Confusion at toll plazas.

• Money deducted twice.

• Blacklisting of your vehicle in the NETC system.

• Action by your issuing bank, including blocking or penalties.

Think of it this way: a toll scanner cannot “decide” which of the two tags is correct if both are present on your windshield. The system will often attempt to deduct from both. Not only does this mean you lose money, but you may also waste hours chasing refunds.

Therefore, the official recommendation is clear: keep only one FASTag per vehicle at all times.

This is another common question. The answer again is: No.

A FASTag is issued against one vehicle’s RC number and its specific vehicle class (car, LCV, truck, etc.). Using the same tag for multiple cars will:

• Trigger class/RC mismatches.

• Lead to blacklisting in the system.

• Result in toll penalties or blocked passage.
  

For fleet owners or families with multiple cars, the solution is simple: buy one FASTag for each car. Banks allow you to manage multiple FASTags under one account or mobile number, but each tag must be separately registered to a vehicle.

If you want to change your FASTag provider — say from ICICI to SBI — follow this process carefully:

1. Check your current tag status using the MyFASTag app or issuer’s portal.

2. Close or deactivate your old tag by contacting your bank. Clear any pending dues.

3. Request a refund of the security deposit, where applicable.

4. Apply for a new FASTag with full KYC details.

5. Affix and test the new tag, ensuring only the new one remains on your windshield.
   

Remember: don’t use two tags simultaneously. Always deactivate the old one first.

If your tag is physically damaged, torn, or lost:

• Contact your issuing bank immediately.

• Request blockage of the old tag to prevent misuse.

• Apply for a replacement FASTag through the same bank.

• A replacement fee (around ₹100) may apply.
  

This ensures you don’t accidentally violate the One Vehicle, One FASTag rule.

If you suspect multiple tags are active on your car:

1. Visit the IHMCL portal or MyFASTag app.

2. Enter your vehicle details to check linked tags.

3. If more than one appears, contact the issuer to close extra tags immediately.
   

This prevents issues at toll plazas and ensures compliance.

Incomplete KYC can result in:

• Tag deactivation.

• Blacklisting after cut-off deadlines.

• Inability to recharge above ₹10,000/month.
  

How to update KYC:

• Visit your issuing bank portal or IHMCL portal.

• Upload RC, Aadhaar, PAN, and photo.

• Complete within the prescribed SLA (Service Level Agreement) period.
  

A fully KYC-compliant FASTag ensures smooth travel and uninterrupted services.

Q1. Can fleet owners manage many tags on one mobile number?
Yes. Multiple tags can be managed on one account, but not multiple FASTags for one vehicle.

Q2. What happens if an old tag remains on the car after new installation?
It may still be read by scanners. Always remove/discard old tags physically.

Q3. Can I temporarily keep two FASTags while switching providers?
Not recommended. Deactivate the old one first to avoid double deductions.

Scenario	Allowed?	What Happens	What to Do
2 FASTags on one car	No	Old deactivated, risk of confusion	Deactivate/close extras; keep latest
1 FASTag across multiple cars	No	RC mismatch, blacklist risk	Buy separate tags per vehicle
Switching banks/providers	Yes	Old must be closed first	Deactivate old; then apply new
Incomplete KYC	No	Tag deactivated or blacklisted	Complete KYC with issuer/IHMCL

• If changing banks → Close old tag → Apply new → Affix only the new one.

• If lost/damaged → Block old → Request replacement.

• If multiple tags are detected → Contact bank → Deactivate extras.
  

To answer the question directly: Can we have two FASTags for same car? No. The One Vehicle, One FASTag rule is strict, enforced, and designed to prevent misuse.

• One vehicle = one active FASTag.

• One FASTag = one vehicle.

• Switching providers is allowed, but only after closing the old tag.

• Multiple tags for one vehicle = risks of double deduction, blacklist, and penalties.

By following the correct process, you avoid fines, confusion, and wasted money — and ensure smooth passage on India’s highways in 2025.
