UIDAI Details

What is UIDAI ?

UIDAI (Unique Identification Authority of India), It is a statutory authority established by the Indian government to issue unique identification numbers, known as Aadhaar, to residents of India. The Aadhaar number serves as a 12-digit unique identification and is used for various government and private sector services, ensuring efficient and targeted service delivery. UIDAI is responsible for the management and authentication of Aadhaar-related data, ensuring the security and privacy of citizens’ information.

The UIDAI was initially operating as an office linked to the Planning Commission (now known as NITI Aayog) before it was created as a statutory entity. The UIDAI is now a component of the Department of Electronics and Information Technology (DeitY), thanks to a government revision made on September 12th, 2015.

In India, the first UID was assigned back in 2010. The first Indian to acquire a UID was a resident of Nandurbar, a rural area of Maharashtra, on September 29, 2010. Aadhaar had 1.22 billion registered users in India as of July 2018.
