An online portal is available for Aadhaar cardholders on the official Unique Identification Authority of India website, as of 2015. The website offers many services associated with Aadhaar cards.
The gateway lets cardholders update their personal identifying information, such as name, address and date of birth, through the kiosk or via a registered mobile phone number. Additionally, if cards are lost, the website allows customers to download their Aadhaar numbers electronically from the system after verification of personal information.
The Aadhaar is a unique number given to India residents, and it is used to apply for and receive state benefits and services.
