Find FASTag ID & Customer ID By Vehicle No., Mobile, SMS & Tag

As FASTag usage experiences widespread adoption in India towards facilitating easy toll payment, it goes without saying that owners will at some time have to pull up information such as their FASTag ID or Customer ID as soon as they can.

All of that, of course, can be accessed as you try to log in to the official FASTag issuing portal website, verify your tag’s NETC status, or reach customer care; finding where to look up these identifiers is important.

Having said all that, yes, it can get confusing. There are customers with only a vehicle number, others with their smartphone or SMS notifications and then many of them are confused about the difference between their FASTag ID and their Customer ID.

This in-depth guide will clarify what these identifiers are, how to find them, and how to use them—whether it is on your windshield, sorting through old emails, or trying to pull information using the issuer’s app or support.

Before discussing the procedures to obtain your FASTag details, it is important to clarify the two widely employed identifiers. Preventing misconceptions in the long term, let’s first identify what each of these IDs actually is.

FASTag ID is the account or tag identifier of your specific FASTag device. Occasionally, it is needed to check the status of your tag through the NETC portal, to reach customer support at your issuer, or on first setup and provisioning. The ID might be visible in your issuer’s app or online portal or sometimes on the sticker on the tag itself. 

At other times, it might be found by reading the QR code on your FASTag. That’s just the way things work.

On the other hand, Customer ID is the login or wallet ID assigned to each individual user specifically by your FASTag provider. It’s typically how you would log in to your FASTag profile on the provider’s website or app. You are usually sent it on SMS or email upon initial activation of the tag, and it’s linked to your profile, vehicle, and transaction history.

Note: The naming conventions vary across providers. Some call it “Wallet ID,” others say “Tag ID,” “Customer ID,” or “Account ID.” Always confirm from official communications and record both identifiers for future use.

If you need these IDs quickly for login or support, start with these simple methods:

1. Check Your Issuer App or Portal

• Log into your bank or issuer’s FASTag app (e.g., Paytm, HDFC, ICICI, Airtel Payments Bank).
• Navigate to:
  • Profile
  • FASTag Section
  • Tag Management or Account Information
• Your Customer ID and FASTag ID are typically displayed here.

2. Search Your SMS and Email Inboxes

• Look for welcome messages or alerts from your FASTag issuer.
• Search for keywords like:
  • “FASTag ID”
  • “Customer ID”
  • “Tag Account”
• Your issuer’s name (e.g., “Equitas FASTag”).
• Check both SMS and email, including spam or promotions folders.

3. Inspect the Physical FASTag Sticker

• Look at the FASTag affixed to your windshield.
• You may see:
  • Printed numbers (FASTag ID or Wallet ID).
  • A QR code, which can be scanned using the issuer’s mobile app to display tag/account information.

4. Contact Your FASTag Issuer

• Call the issuer’s customer care number (available on the FASTag portal).
• Provide:
  • Your Vehicle Registration Number (VRN).
  • Registered mobile number.
• After verifying your identity, the support team will help retrieve the required IDs.

Looking to gain instant access to your FASTag ID? Here’s what you have to do:

1. Use the Issuer’s Portal or App

• Many FASTag issuers allow you to recover or track your FASTag ID using your Vehicle Number.
• Look for options like:
  • “Forgot ID”
  • “Manage My FASTag”
  • “Track My Tag”
• You’ll need to enter:
  • Vehicle number (VRN).
  • Registered mobile number.
  • OTP for verification or KYC details.

2. Check NETC Portal

The National Electronic Toll Collection (NETC) portal allows you to check your FASTag status.

How to use:

• Go to https://www.npci.org.in
• Navigate to Check FASTag Status.
• Enter:
  • Your Vehicle Registration Number (VRN) or FASTag ID, depending on the option.
• It will show:
  • FASTag status (active/inactive).
  • Issuing bank.
  • Some linked account information (if available).

Note: The NETC portal does not issue or retrieve Customer IDs. It’s only for checking tag status.

In some contexts, especially during FASTag provisioning or account linking, you might encounter a 24-digit FASTag ID. This long identifier is used behind the scenes to map the physical tag to your issuer’s systems.

You may come across it during:

• Initial tag setup.
• Scanning the QR code with your issuer’s app.
• Communications from the issuer (in email or portal).

While this 24-digit number isn’t always needed for day-to-day use, it’s a good idea to note it down if it’s visible during setup. Just like the shorter FASTag and Customer IDs, this long identifier can occasionally be useful for troubleshooting or system mapping.

If you’re ever unsure which ID is required, go by the labels in your issuer’s portal:

• Use Customer ID when logging into the app or for support calls.
• Use FASTag ID or Tag ID for NETC checks and toll-related issues.

Step-by-step Retrieval Guides for FASTag IDs

Onboard so far? Good, let’s keep on exploring more.

Now it’s time to break down each method of finding your IDs with more detail and clarity.

1. Through the Issuer Mobile App

Begin by downloading your bank or wallet provider’s FASTag application. After logging in by using your registered mobile number, go to your profile or the FASTag account. You will find details like your vehicle number, status of the tag, Customer ID, and FASTag/Tag ID. These are normally simple to copy or screenshot to keep for reference in the future.

2. Using the Issuer Website

Log in on your issuer’s FASTag portal. If you cannot remember your credentials, then use the “Forgot ID” or “Forgot Password” feature, which typically requires OTP validation on the registered mobile. Look at spaces like “My Wallet,” “Tag Management,” or “Account Summary” from inside. These are the spaces where identifiers are usually displayed.

3. Using SMS or Email

If you have access to either your phone or your email inbox, browse through older messages sent by your FASTag provider. Welcome SMS messages often include your Customer ID, but transaction or charge alerts may mention either your FASTag or Wallet ID. Double-check spam or promotional folders, too, because sometimes these messages are filtered.

4. Using the Physical Tag

See the FASTag sticker on your car’s windshield. Depending upon your issuer, either the FASTag ID may be directly printed on it. If it has a QR code, scan it through the official FASTag app of their issuer and never through a third-party app to display the associated ID. If the number printed on it appears to be other than what is being displayed by your app, believe the app’s information and get in touch with support to clarify.

FAQs and troubleshooting

1. What if I don’t have access to the app or portal?

If you’ve lost or forgotten credentials or lost access, then click on “Forgot ID” or “Forgot Password” on the app or portal. You will usually be required to input your registered phone number, and you may be required to verify the vehicle registration number, too. You may otherwise contact customer care and perform identity authentication to re-establish access.

2. The ID on my sticker doesn’t match the one in the app. What should I trust?

Make sure to always verify information on display in your issuer’s app or portal because it will reflect the active, real-time tag status. If it is mismatched, contact support to have it rectified.

3. Can the NETC portal show my Customer ID?

No. The NETC status checker is meant to validate your FASTag’s activation status and issuer info using either your FASTag ID or vehicle number. It cannot retrieve your login credentials or Customer ID.

4. My bank provided a 13-digit ID starting with “17.” What is it?

Some issuers, particularly banks like ICICI or IDFC, assign Customer IDs in specific formats. A 13-digit number beginning with “17” is likely your Customer ID and should be used for login and support purposes.

Where to Find Each FASTag ID

Identifier	Where to Find	What It’s Used For
Customer ID	Issuer app/portal, welcome SMS/email	Login to app/portal, customer support verification
FASTag/Tag ID	Issuer app/portal, on tag sticker or revealed via QR scan	NETC status check, support ticket, tag tracking
24-digit ID	Shown during tag provisioning or QR scan	Internal tag mapping, sometimes required for linking

Conclusion

Whether it is to log in to your FASTag account in order to check your toll balance or to change your vehicle information, it is necessary to know how to find your Customer ID and FASTag ID. These are utilized in order to unlock your tag, check status, and troubleshoot issues with your bank or wallet service provider.

Fortunately, these are readily available in easy ways. You are able to look up the mobile app or online portal of your issuer, check your SMS mailbox or onboarding message, or even look at the FASTag sticker on the windshield of your vehicle.

For the majority of cases, you only need your Vehicle Registration Number (VRN) to fetch your FASTag details by using the official issuing utilities or the NETC portal.
