Why UIDAI Mobile Number Link is Important
The UIDAI Mobile Number Link ensures that your Aadhaar can be verified through OTP. Without a linked number, many services stop at the verification stage.
For example, if a student in Mumbai tries to download e-Aadhaar or update address after shifting to a hostel, the request will not complete without OTP authentication on the registered number.
Who Should Complete Mobile Number Link
You should go for the Mobile Number Link or update if:
- Your old number is switched off or lost
- You have changed your SIM recently
- Your Aadhaar was created without a mobile number
This situation is common among people who enrolled for Aadhaar many years ago and are now trying to use online services.
