The UIDAI (Unique Identification Authority of India) is the statutory body responsible for handling all Aadhaar-related services in India. It was established under the Aadhaar Act of 2016 (Targeted Delivery of Financial and Other Subsidies, Benefits and Services). The MeitY (Ministry of Electronics and Information Technology) under the Government of India established the UIDAI on 12th July 2016. The Aadhaar Act of 2016 has been amended to the Aadhaar and Other Laws Act of 2019, with effect from 25-7-2019.

Before the UIDAI was established as a statutory body, it was initially functioning as an office attached to the Planning Commission (which is now known as NITI Aayog). On 12th September 2015, the government revised it to bring the UIDAI under the DeitY (Department of Electronics and Information Technology).

The UIDAI was created to issue Unique Identification Numbers (UID) popularly known as Aadhaar number to all residents of India. The UID serves to eliminate fake and duplicate identities while providing government services and service providers with an easy and cost-effective way to verify authentication.

The first UID number in India was issued way back in 2010. On 29th September 2010, a resident in the rural district of Nandurbar, Maharashtra, became the first Indian to receive a UID. As of July 2018, 1.22 billion Indians were enrolled in Aadhaar.

The Aadhaar number provides residents with a unique identity. It prevents fake and duplicate identities. It can be easily authenticated and verified anytime and from anywhere. The Government of India issued a letter on 16th December 2010, stating that the Aadhaar number issued by the UIDAI serves as a valid document for identity proof and address proof. However, you have to note that the Aadhaar was not intended to replace any of the present government-issued documents. It does not give rights to citizenship to cardholders.
