How to link Aadhaar card to phone number?

To link your Aadhaar card to a phone number, you must visit a permanent Aadhaar Enrolment Centre or Aadhaar Seva Kendra, as this process cannot be completed online. Fill out the Aadhaar correction form with your current mobile number and submit it to the executive. You will need to provide biometric authentication for verification. A fee of 50 rupees is generally applicable for this service. Once updated, you will receive an acknowledgement slip with an Update Request Number to track the status.
