How to Change Mobile Number in FASTag

Keeping the mobile number registered with your FASTag account up-to-date is important, it ensures you receive toll deduction alerts, low-balance notifications, and account-related OTPs. The process varies slightly across issuers but follows a consistent pattern.

Step 1: What You Need Before You Update

• FASTag account details: issuing bank, wallet or tag ID.
   
• New mobile number that is active and preferably in your name.
   
• Valid identity proof (Aadhaar, PAN, driving licence, etc.).
   
• Vehicle registration certificate (sometimes required).
   
• Login access to your FASTag issuer’s portal or app, or ability to visit a branch.
   

Step 2: How to Change the Mobile Number

Online Method

• Log into your FASTag issuer’s web portal or mobile app.
   
• Navigate to Profile / My Account / Service Request (or equivalent) and select “Update Mobile Number.”
   
• Enter the new mobile number and submit the request.
   
• You’ll receive OTP(s) — often to the new number, and in some cases to the old number for verification.
   
• After verification, you will get a confirmation SMS on the new number.
   

Offline Method

• Visit a branch of your FASTag issuer bank or authorised sales point.
   
• Ask for a “Mobile Number Update” form or KYC update form.
   
• Fill in your old and new mobile numbers and attach ID proof, vehicle RC if required.
   
• Submit the form; the bank processes the change and sends confirmation SMS once complete.
   

Step 3: Key Notes & Tips

• Ensure the new mobile number is active and capable of receiving SMS/OTP.
   
• Some issuers won’t allow updating to a number already linked to another FASTag wallet.
   
• While many banks support online updates, some may still require offline steps depending on your account or tag type.
   
• After the update, check that you continue receiving alerts for toll deductions — this confirms linkage is correct.
   
• Retain copies of any submitted documents or forms until you get confirmation.

Conclusion

Updating the mobile number linked to your FASTag is a straightforward but necessary step to maintain smooth toll payments, alert delivery, and account security. Use the online method where available for speed; otherwise, visit your issuing bank branch. Follow the issuer’s specific steps, verify OTPs carefully, and you’ll be back on the road with full notifications in no time.
