Aadhaar, which means "foundation" in many Indian languages, is the term for the unique identity number issued by the UIDAI. No resident can have a duplicate number since it is linked to their individual biometrics; thereby identifying fake and ghost identities which result in leakages today. Savings from eliminating duplicates and fakes through Aadhaar-based identification will further enable governments to expand benefits to other eligible residents.
It is a 12 digit individual identification number issued by the Unique Identification Authority of India on behalf of the Government of India. This number will serve as a proof of identity and address, anywhere in India. Aadhaar letter received via India Post and e-Aadhaar downloaded from UIDAI website are equally valid.
