FASTag may suddenly stop working! If you don't have KYV, you could be stuck at the toll.

FASTag: KYV is a verification process that ensures that the FASTag is linked to the vehicle it's installed on. The vehicle owner must upload their vehicle's registration certificate (RC) and a photo of the vehicle to confirm that the tag is installed on the correct vehicle.

FASTag: If your FASTag suddenly stops working or displays "Inactive" at a toll plaza, you're not alone. Many vehicle owners across the country have faced this issue in recent months. The biggest reason for this has been the Know Your Vehicle (KYV) verification. Now, the National Highway Authority of India (NHAI) has simplified this process in 2025, making FASTag use easier than ever.

What is KYV (Know Your Vehicle)?

KYV is a verification process that ensures that the FASTag is linked to the vehicle it is installed on. Under this, vehicle owners must upload their vehicle's registration certificate (RC) and a photo of the vehicle to confirm that the tag is installed on the correct vehicle. This rule was implemented at the end of 2023. It was intended to prevent toll tax abuse, especially in cases where commercial vehicles and cars were misusing FASTags. However, the process proved to be quite cumbersome for ordinary drivers.

Why was the KYV process changed in 2025?

Over the past year, a large number of complaints have surfaced that FASTags are suddenly blocked if the KYV is not completed, requiring vehicles to stop at toll plazas and incurring additional fees. In light of these problems, NHAI and IHMCL (Indian Highways Management Company Limited) decided to simplify the KYV process.

Major Changes to the KYV Process in 2025

The new guidelines issued in 2025 introduce several significant changes. First, the photo uploading process has been simplified. Vehicle owners will now only need to upload a front photo, clearly showing the number plate and the FASTag installed on the windshield. Side or rear photos are no longer required. Another major change relates to automatic RC verification.

By entering the vehicle number, chassis number, or mobile number, the system will automatically retrieve RC information from the government's VAHAN database. Furthermore, FASTags will no longer be immediately disabled if the KYV is incomplete. Previously, the tag would be blocked without any warning, but now SMS reminders will be sent first.

If multiple vehicles are linked to the same mobile number, users are now allowed to select the vehicle of their choice and complete the KYV. Furthermore, if someone faces difficulty uploading documents, the FASTag-issuing bank will be obligated to assist the user.

How to complete KYV? (Step-by-Step)

To complete KYV, vehicle owners must first visit the website https://fastag.ihmcl.com.

Follow this step by step process.

Upload a front photo of the vehicle, clearly showing both the number plate and FASTag.

The RC information will automatically appear in the system, and after confirming it, the KYV can be submitted.

What to do if you encounter a problem with KYV?

If you encounter any issues with KYV, vehicle owners can call the National Highway Helpline number 1033 or contact their FASTag issuing bank directly.

Why is KYV necessary?

The primary purpose of KYV is to make the FASTag system more transparent, secure, and reliable. It helps ensure strict enforcement of the "One Vehicle, One FASTag" rule, thereby curbing toll tax evasion and misuse.
