Update Mobile Number in Aadhar Card

The Government of India has created an official website and app for Aadhaar, India’s national identification program. With these resources, users can make changes to their Aadhaar information, check its status, and verify it online. To use the Aadhaar website or app, however, you must have a mobile number registered with your Aadhaar. This is because a one-time password (OTP) is sent to the registered mobile number for authentication purposes. 

Without a mobile number registered with your Aadhaar, you will be unable to access most online services provided via the portal or app. In this article, we will explain how to update and register a mobile number with your Aadhaar card.

How to Register Mobile Number with Aadhaar Card?

You can add or register your mobile number with your Aadhaar card by following the steps below:

  • Go to the official website of UIDAI (Unique Identification Authority of India)
  • Navigate to the “My Aadhaar” section and select “Locate an Enrolment Center”
  • Search for your nearest enrolment centre using the state, postal code, or search box options
  • Visit the nearest enrolment centre and fill out the form, including your mobile number
  • Provide your biometric details for authentication purposes
  • Review and verify all the information you have provided
  • Pay a fee of Rs. 50 to have your mobile number updated
  • Collect your acknowledgement slip to track the status of your Aadhaar update
  • Your mobile number will be registered with your Aadhaar card once the process is complete.

How to Update a Mobile Number with an Aadhaar Card?

If your registered mobile number has changed or is no longer in use, you can update it with your Aadhaar card by visiting an official enrolment centre. This requires a personal visit to an enrolment centre, where you will provide necessary documentation and biometric details for authentication. Once the update is complete, your new mobile number will be registered with your Aadhaar card.

To find the nearest Aadhaar enrolment centre, follow the given instructions: 

  • Go to the official website of UIDAI (Unique Identification Authority of India)
  • Navigate to the “My Aadhaar” section and select “Locate an Enrolment Center”

  • Fill out the form with the appropriate information and click the “Search” button to find your nearest enrolment centre.

Points to be noted:

  • The mobile number associated with your Aadhaar is used to keep you informed about any updates or changes related to your Aadhaar.
  • A one-time password (OTP) will be sent to your registered mobile number when you need to download an e-Aadhaar card.
