To establish unique identification of every single person, UIDAI (Unique Identification Authority of India), on behalf of the government of India, created a centralized database for collecting biometric and demographic data of residents and issued a unique 12-digit number known as AADHAAR Number.

Aadhaar is proof of identity and address, valid for a lifetime. It is issued in the form of a letter delivered via post to the address mentioned in the application.

What is Aadhaar Card?

Aadhaar Card is a unique identification number issued by the Indian government to residents of India. It is a 12-digit number that serves as proof of identity and address. Aadhaar is issued by the Unique Identification Authority of India (UIDAI), a statutory authority established in January 2009 under the provisions of the Aadhaar Act, 2016.

The Unique Identification Authority of India (UIDAI) is the main agency that operates under the Government of India and is tasked with issuing Aadhaar Cards to individuals. UIDAI collects the biometric and demographic data of the applicants and stores it in a centralized database. After the data is collected and verified, a unique Aadhaar number is issued and printed on the Aadhaar Card. The Aadhaar card contains the following information:

  • Full name of the individual
  • Unique 12-digit Aadhaar number
  • Address
  • Gender
  • Date of birth
  • Photograph
  • Biometric data (fingerprints and iris scan)

Moreover, there is a QR code on the card which can be scanned to access the details of the cardholder easily.

What is Baal Aadhaar?

"Aadhaar for kids" or "Aadhaar for children." This is a blue-colored Aadhaar card and is known as the "Baal Aadhaar".

  • Baal Aadhaar does not contain the biometric information of the child.
  • When a child attains the age of five, it is mandatory to get Baal Aadhaar updated with biometric information
