The long wait at the toll booth behind several cars can be tiresome, especially when you need to hurry to your destination. However, this problem and the added inconvenience of fumbling for change when it is your turn at the booth are now being resolved, thanks to the FASTag!

FASTag was introduced in India in 2014 by the National Highways Authority of India (NHAI) to promote electronic toll collection and reduce congestion at toll plazas. The system was initially implemented on a pilot basis on selected national highways and has since been rolled out across the country. The use of FASTag has been made mandatory for all vehicles in India since December 15, 2019.

Let’s find out more about this feature and why your vehicle number is an important part of your FASTage customer ID.

What is FASTag?

FASTag is an electronic toll collection system in India that enables automatic toll payment without needing cash transactions.

It uses Radio Frequency Identification (RFID) technology and is affixed to the windscreen of a vehicle. The toll fee is automatically deducted from the linked prepaid or savings account when the vehicle passes through a toll plaza. This helps to reduce the waiting time at toll plazas and improve the efficiency of toll collection. FASTag is a reusable, reloadable tag that can be used across all toll plazas in India that accept electronic toll payments.

Importance of Linking the Vehicle Number to the FASTag Customer ID

Before discussing the relation between the vehicle number and FASTag, it is essential to know that the customer ID is crucial information for a FASTag account. It acts as a unique identifier for the customer. It links the customer's account to their vehicle and ensures that the correct amount is deducted from their account each time they use a toll plaza.

The customer ID tracks the vehicle's toll payments and updates the account balance as transactions are processed. Using the FASTag system and making electronic toll payments with the customer ID may only be possible. The vehicle number is linked to a FASTag customer ID during the FASTag activation process. When you apply for a FASTag, you need to provide your vehicle details, including the number, to the issuing authority. This information is then linked to your customer ID, creating a unique account for you.

The Customer ID also allows customers to view their transaction history, check their account balance, and manage their FASTag account. In short, the Customer ID is essential for the smooth functioning of the FASTag system. When the FASTag is affixed to the vehicle's windshield, it allows for seamless toll payments as the vehicle passes through toll plazas equipped with RFID readers.

Steps to Find the FASTag Customer ID Using the Vehicle Number

If you are wondering how to find your FASTag ID number using the vehicle number in India, these are some of the ways:

  1. Visit the official FASTag website: On the official website of the National Highways Authority of India (NHAI), you can find the customer ID by entering the vehicle number and other details.
  2. Contact the issuing bank: If you have a FASTag account with a bank, you can contact the bank's customer service department, and they will be able to provide you with your Customer ID.
  3. Check the FASTag physical tag: The FASTag physical tag, which is affixed to your vehicle's windshield, will have the customer ID and other details printed on it.
  4. Call the customer service number: You can call the FASTag customer service number provided by the NHAI, and they will assist you in finding your Customer ID.

It's important to have your Customer ID handy as it is required for various transactions, such as checking the account balance and updating personal details. If you choose to visit the NHAI website to find your FASTag customer ID, these are the steps you can follow:

  • Visit the official website of the issuing authority of the FASTag, such as the National Highways Authority of India (NHAI) or the Indian Highways Management Company Limited (IHMCL).
  • Look for the "FASTag" section on the website and find the option to "Track FASTag.
  • Enter the vehicle number in the designated field.
  • Provide other required information, such as the state of registration and the type of vehicle.
  • Click on "Track" or "Submit" to initiate the search.
  • The FASTag customer ID will be displayed on the screen, along with other details related to the account.

If you want to change your vehicle number under the same FASTag, all you need to do is follow these steps:

  • Contact the issuing bank or the point of sale (POS) where you purchased the FASTag.
  • Provide the new vehicle number and other required details, such as your FASTag number, personal details, and old vehicle number.
  • The bank or POS will verify the information and update the details in their system.
  • You may be required to pay a fee for the change.
  • Once the change is complete, you can use the FASTag with the new vehicle number.

Is FASTag Important for Car Insurance?

The Ministry of Road Transport and Highways had proposed that a FASTag is a mandatory requirement for buying a third-party car insurance policy. This means the FASTag details will be documented in your car insurance policy. While having third-party car insurance for your vehicle is a legal and compulsory requirement and may also be necessary for receiving FASTag, the liability-only coverage will only protect you against the financial losses arising from third-party damages caused by your insured car.

For this reason, purchasing a comprehensive four-wheeler insurance policy is advisable to safeguard your four-wheeler against a range of damages. These can be due to natural calamities such as floods, landslides, etc., human causes like terror strikes, rioting and others and accidental means such as fires, explosions, implosions and the like.

Moreover, comprehensive car insurance plans, like the ones at Tata AIG, are quite customisable. You can compare car insurance policies and add a Personal Accident Cover and a range of other optional add-ons to your car insurance plan for enhanced coverage.


As you can see, the process of finding your FASTag customer ID online can be really simple. Moreover, the use of FASTag can be beneficial, especially if you travel regularly between different towns or cities quite frequently.
