TL;DR: NHAI and NPCI enforce the strict ‘One Vehicle, One FASTag’ regulation to eliminate multiple tags per vehicle and prevent toll evasion. If your FASTag is issued by State Bank of India (SBI) or HDFC Bank, you can update your KYC documentation entirely online within 10 minutes without visiting a bank branch. You only need your vehicle’s Registration Certificate (RC), Aadhaar card, PAN card, and the registered mobile number. Complete verification unblocks blacklisted tags within 24 hours.

Driving across national highways in India requires an active, fully validated FASTag affixed to your vehicle’s windshield. According to the National Highways Authority of India (NHAI) and the Indian Highway Management Company Limited (IHMCL), over 98% of highway toll collections in India are processed electronically through the National Electronic Toll Collection (NETC) programme.
However, hundreds of thousands of vehicle owners face unexpected toll booth delays, blacklisted tag warnings, or double-toll penalties because of incomplete Know Your Customer (KYC) documentation. In compliance with Reserve Bank of India (RBI) prepaid payment instrument guidelines and MoRTH directives, banks must deactivate tags that fail periodic KYC validation.
Whether you received an SMS alert warning that your tag will be suspended, or your FASTag status displays “Blacklisted” or “Low Balance” despite having funds, this comprehensive 2026 guide walks you through updating your FASTag KYC online for State Bank of India (SBI) and HDFC Bank without ever stepping inside a branch.
What is the ‘One Vehicle, One FASTag’ Rule?
The National Highways Authority of India introduced the ‘One Vehicle, One FASTag’ initiative to streamline highway electronic toll collection and deter drivers from linking a single tag to multiple cars or maintaining multiple active tags for a single vehicle.
Under these regulations:
- Single Active Tag per Vehicle: A vehicle registered with a specific Registration Certificate (RC) number can only have one active FASTag linked to its chassis and registration number.
- Deactivation of Previous Tags: If you purchase a new FASTag from a different bank (for example, switching from Paytm Payments Bank or ICICI to SBI), your previous tag must either be surrendered or it will be marked non-operational.
- Mandatory Full KYC: Tags issued with minimum KYC (which permitted limited monthly wallet balances up to ₹10,000) expire after 24 months. Tag holders must complete biometric or digital Aadhaar OVD (Officially Valid Document) KYC to upgrade to a full KYC prepaid wallet with limits up to ₹1,00,000.
If your issuer bank cannot verify your RC and Aadhaar credentials, your FASTag status switches to “Deactivated” or “Blacklisted” at toll plazas, forcing you to pay twice the toll rate in cash or via UPI at toll lanes.
Required Documents Checklist for Online FASTag KYC
Before beginning the online update process on either the SBI or HDFC web portal, gather clear digital copies of the following documents:
- Vehicle Registration Certificate (RC): Scanned front and back copy showing vehicle registration number, chassis number, and engine number. Ensure the image is crisp (JPEG or PDF under 2 MB).
- Identity & Address Proof (Officially Valid Document): Aadhaar Card, Passport, Voter ID, or Driving Licence. Aadhaar OTP verification requires your mobile number to be linked with UIDAI.
- Permanent Account Number (PAN) Card: Mandatory for financial compliance. If you do not have a PAN card, Form 60 must be submitted online.
- Passport-Size Photograph: Clear front-facing image of the vehicle owner (under 1 MB).
- Active Registered Mobile Number: The phone number linked to your FASTag wallet to receive one-time passwords (OTP).
Step 1: How to Check Your FASTag KYC Status Online (IHMCL Portal)
Before uploading documents, verify whether your FASTag actually requires KYC renewal or if the issue stems from an unlinked bank wallet. IHMCL provides a central portal to check any tag’s status across all 32 NETC partner banks:
- Visit the official IHMCL Customer Portal at
fastag.ihmcl.com. - Click on Login using your registered mobile number and password, or authenticate using OTP.
- Once logged in, navigate to the My Profile section in the left sidebar.
- Review the KYC Status row:
* Active / Verified: Your KYC is complete; no further action is necessary.
* Pending / Incomplete: You must upload your RC and ID documents immediately.
* Blacklisted / Suspended: Your issuer bank has blocked tag transactions due to KYC lapse or negative balance.
- Alternatively, check the Vehicle Status tab, enter your vehicle’s registration number (e.g.,
MH12AB1234orDL01CA5678), and view all issued tags associated with your chassis number.

Expert Recommendations to Avoid Toll Booth Fines
- Maintain a ₹300+ Buffer: Most highway toll plazas deduct minimum threshold security deposits ranging between ₹100 and ₹200. Always keep at least ₹300 to ₹500 in your wallet before undertaking inter-state expressway trips.
- Position Correctly: Affix the FASTag horizontally directly behind your interior rear-view mirror on the upper edge of the windshield. Avoid placing the tag over dark UV sun-film or near metallic dashboard dashcam wiring, which can block the 865–868 MHz RFID radio signal.
- Keep Soft Copies in DigiLocker: Keep your driving licence, RC, and vehicle insurance stored in DigiLocker or mParivahan. Toll authorities accept verified electronic documents if roadside verification is requested.

How long does it take to unblock a blacklisted FASTag after KYC update?
Once your documents are uploaded and approved by your bank, the blacklisted status is updated on the NPCI central mapper within 2 to 24 hours.
What happens if I drive through a toll lane with an inactive FASTag?
Under National Highway Fee Rules, vehicles entering a dedicated FASTag lane with an invalid, blacklisted, or inactive tag must pay double the regular toll fee in cash or UPI.
