Link Your Mobile Number to Aadhaar Before the Next OTP Fails

Mobile number can only be added or changed at an Aadhaar enrolment centre, not on the myAadhaar website

The fee is ₹75 as a standalone demographic update; it's free if done alongside a biometric update

No document is needed — just your Aadhaar and your fingerprint or face at the centre

Almost every Aadhaar OTP, DigiLocker login and bank KYC depends on the number UIDAI has on file

Linking your number to Aadhaar's record is different from Aadhaar-SIM linking for your telecom KYC
