As you have lost your registered mobile number, you cannot update your number in Aadhaar through online. This is because, when you try to update your mobile number through online, an OTP will be send to your registered number, which you have already lost.

So you need to update the number in Aadhar by visiting the nearest Aadhaar enrollment centre. You will be asked to fill a form like this.


Earlier, there used to be a check box to indicate that Phone number is to be updated. Recent versions have removed it. Once you fill this form, ask the Data Entry Operator to only modify the telephone number. Operator will verify your biometric details before updating the new number.

It will take around 7 days to reflect the change.

  • Enrollment officer takes your biometrics to authenticate your identity
  • Officer hands over the acknowledgement slip containing URN to you
  • The URN can be used to check the status of aadhar online.
  • You have to pay a fee of INR 50/- to the executive
