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

If you do not have a mobile number registered with your Aadhaar, you will not be able to access most of the online services provided by the app. In this article, we will explain how to update and register a mobile number with your Aadhaar card.
