What is Aadhaar & Who Needs to Enrol?

Aadhaar is a 12-digit unique identification number issued by the Unique Identification Authority of India (UIDAI) to all residents of India. It is linked to your biometric data — fingerprints, iris scans, and photograph — making it one of the most secure identity systems in the world. With over 1.38 billion Aadhaar holders, it is the world’s largest biometric ID system.

You need one Proof of Identity (POI) and one Proof of Address (POA) in original with photocopies. Optionally, carry Proof of Date of Birth (PDB). All documents are returned to you after scanning at the centre.
