Let us give you the straight answer first.
No official tool takes a vehicle registration number and returns a FASTag Customer ID properly.
HDFC Bank and Axis Bank let you log in with the car number and an OTP, which is a one-time password sent to your registered mobile number, but other banks do not. The National Payments Corporation of India (NPCI) has a status page that accepts a car number too, yet it shows the state of your tag and not an ID.
So does the blog end here ?
Don’t Worry… You still have a workable route, and we will walk you through it together.
This guide covers what a customer ID is, which banks let you start with a car number, the steps to follow and what to do if the bank's page turns you away.
What a FASTag Customer ID Is and Why Banks Name It Differently
Three numbers often get mixed up, so let us separate them.
Vehicle registration number: This is the number on your number plate, for example MH04BB1234. It is public, so it does not work like a password.
Tag ID: This is a 24-character code for the sticker itself, such as 34161FA820327FA4C81A1820. The NPCI status page accepts it.
Account ID: This identifies your account with the issuer, which is the bank that sold you the tag. Banks call it a Customer ID, a Wallet ID or a User ID.
The third number is where the confusion starts. Data sourced from the NPCI and IHMCL websites shows no national definition of a Customer ID, so each bank sets its own label.
HDFC Bank issues a Customer ID and a separate FASTag Wallet ID, and it sends both to your registered email and mobile number.
ICICI Bank calls its login name a User ID. In short, the FASTag Customer ID you need depends on your bank, and at HDFC Bank it is a different number from the Wallet ID.
Which Banks Accept a Car Number Login
The table below shows how six issuers handle a FASTag login, which is the first step towards your FASTag Customer ID.
| Issuer | Car number accepted | What the login page asks for |
|---|---|---|
| HDFC Bank | Yes, with OTP | Mobile number, car number or Wallet ID |
| Axis Bank | Yes, with OTP | Mobile number, car number or Wallet ID |
| ICICI Bank | No | Mobile number or User ID, then OTP |
| SBI | No | Mobile number, password and captcha |
| Airtel Payments Bank | No | Mobile number, then OTP |
| NHAI FASTag portal | No | Mobile number, then password or OTP |
Note: The table reflects the login pages as on October 29, 2026. They carry no date and can change, so please confirm the login box on your own bank's page. The table covers six of the 26 issuer banks that IHMCL has certified.
Step by Step to Your FASTag Customer ID
Shall we begin? Five steps cover most owners.
Find your issuer: Look for the SMS or welcome email from the day you bought the tag, because it names the bank.
Open the bank's own page: Type the bank's official address or use its app, and avoid advertisements and "finder" sites.
Use the FASTag login your bank offers: Enter your car number if the box accepts it, or the mobile number or User ID if it does not.
Complete the OTP or password step: The page sends the OTP to the mobile number registered with the bank, so please keep that phone beside you.
Note the ID: If the account screen shows an ID, write it down. The label may read Customer ID, Wallet ID or User ID.
If your bank is HDFC Bank or Axis Bank
At HDFC Bank, type your car number in the login box and request the OTP. The login opens your account, yet the Customer ID arrives as a separate number in the email and SMS the bank sent at purchase, so please search your inbox and messages for it.
At Axis Bank, stay on the "Login with OTP" tab, type your car number and the verification code shown in the image, then request the OTP. First-time users should keep their FASTag Wallet ID and date of birth ready to set up online access.
If your bank is another issuer
ICICI Bank: Choose "Individual Login", then enter the registered mobile number or the User ID, followed by the OTP.
SBI: Enter the registered mobile number, the password and the captcha. The page has a "Forgot Password" link if you need it.
Airtel Payments Bank: Enter the registered mobile number and the OTP, then open the FASTag section, which sits in the Airtel Thanks app.
NHAI FASTag portal: Enter the mobile number, then request the OTP or type the password.
When the Bank's Page Does Not Let You In
If the page rejects your details, a phone call is the official fallback. IHMCL says an owner with a bank-issued tag can call the toll-free number printed on the back of the tag and share the registered mobile number and the car number.
After verification, the bank gives the information. Owners of an NHAI FASTag can call 1033 instead.
The 1033 helpline mainly handles toll-plaza complaints. Start with your issuer's number, and use 1033 for a plaza problem or when the issuer's helpline does not answer.
Safe Habits While You Search
Four habits keep your account safe.
Avoid finder pages: NPCI, IHMCL and the banks provide the official routes, and a third-party page only adds risk.
Keep the OTP private: The OTP is the last step of the login, so a caller who asks for it can take over your account.
Skip PIN requests: No official FASTag login asks for a card PIN or a UPI PIN.
Refuse to pay for an unblock: A blacklist is an issuer action, and the issuer's helpline handles it.
A Final Word
Your car number cannot fetch a FASTag Customer ID by itself, but it opens the door at HDFC Bank and Axis Bank, and a call to your issuer settles the rest. Find the bank first, use its official page and keep your registered mobile close. Park+ is here for the next step too, whether that is a recharge or a fresh tag.
FAQs
Can I find my FASTag Customer ID with only my vehicle registration number?
No official lookup does this properly. HDFC Bank and Axis Bank accept the car number as a login with an OTP, and the account then opens. Other banks need a mobile number, a User ID or a password.
Does the NPCI FASTag status check show my Customer ID?
Not properly only the 4 digits. NPCI describes it as a status check, and IHMCL says it shows the status of the tags linked to the car. It needs a car number or a Tag ID and a captcha.
Is a FASTag Wallet ID the same as a Customer ID?
Not always, for example HDFC Bank issues them as two numbers and sends both to your registered email and mobile number.
What can I do if I cannot log in?
Call the toll-free number on the back of your tag, and share your registered mobile number and car number. For an NHAI FASTag, call 1033.
Can I still recharge an old Paytm FASTag?
No. NHAI's advisory of March 13, 2024 asked users to move to another bank, and recharge and top-up stopped after March 15, 2024. The existing balance could still pay tolls, so please check the tag's present status with Paytm or a new issuer.
