Registered mobile number is essential to access Aadhaar Online Services. The Aadhaar number and registered mobile number of the resident are required to login to the portal. The resident is authenticated using OTP on his/her registered mobile number.
If you have not registered your Mobile number while enrolling for Aadhaar, you are required to visit a Permanent Enrolment Centre to get it registered.
