How to update a mobile number through the Aadhaar app?

Scenario 1: If the Aadhaar Number Holder is registered on the Aadhaar app using the same mobile number that is registered with Aadhaar, ANH will be required to verify the new mobile number with OTP, perform Face Authentication, and pay the prescribed charges

 Scenario 2: If the Aadhaar Number Holder is registered on the Aadhaar app using a different mobile number from the one registered with Aadhaar, ANH will be required to verify both the old registered mobile number and the new mobile number with OTP, perform Face Authentication, and pay the prescribed charges

 Scenario 3: If the Aadhaar Number Holder does not have access to the old registered mobile number or has not registered a mobile number earlier, ANH must visit the nearest Aadhaar Seva Kendra or an authorised Aadhaar enrolment and update centre to update or register their mobile number.
