The UIDAI is mandated to assign a 12-digit unique identification (UID) number (termed "Aadhaar") to all the residents of India. The implementation of the UID scheme entails generation and assignment of UIDs to residents; defining mechanisms and processes for interlinking UIDs with partner databases; operation and management of all stages of the UID life cycle; framing policies and procedures for updating mechanism and defining usage and applicability of UIDs for delivery of various services, among others. The number is linked to the resident's basic demographic and bio-metric information such as a photograph, ten fingerprints and two iris scans, which are stored in a centralized database

The UIDAI was initially set up by the Government of India in January 2009, as an attached office under the aegis of the Planning Commission via a notification in the Gazette of India. According to the notification, the UIDAI was given the responsibility to lay down plans and policies to implement the UID scheme, to own and operate the UID database, and to be responsible for its updating and maintenance on an ongoing basis.

The UIDAI data centre is located at the Industrial Model Township (IMT), Manesar, which was inaugurated by the then Chief Minister of Haryana Bhupinder Singh Hooda on 7 January 2013. Aadhaar data is kept in about 7,000 servers in Bengaluru and Manesar.
