Unique Identification Authority of India (UIDAI)

On July 12, 2016, in accordance with the Aadhaar Act 2016, the Indian government founded the Unique Identification Authority of India (UIDAI) as a formally recognized statutory authority. The UIDAI’s headquarters are located in New Delhi, and it additionally maintains approximately eight regional offices distributed across India.

This blog will explain everything you need to know about UIDAI and the Aadhaar UID Card.

What is UIDAI?

The UIDAI full form is the Unique Identification Authority of India. It is an organization established by the Indian government in January 2009. Its primary objective is to furnish individuals with a distinctive identification and a digital authentication platform usable globally and at any moment. This authority is responsible for collecting both biometrics (such as iris scans, fingerprints, and photographs) and demographic information from Indian residents. All of this data is stored centrally. The resulting Aadhaar consists of a 12-digit distinctive number, signifying the world’s most extensive project for a National Identification Number. The UID’s data center is situated in Model Township, Manesar, Haryana.

Concise History of UIDAI

Initially under the purview of the Planning Commission, now known as the NITI Aayog, UIDAI’s jurisdiction shifted in 2015 through amendments to the “Allocation of Business Rules.” It was brought under the governance of the Department of Electronics and Information Technology. The first UID number also referred to as Aadhaar, was issued to a resident in Nandurbar, Maharashtra, in 2010. The agency presently oversees enrollment, authentication, and the complete life cycle management of Aadhaar cards.
