Overview

What is an Aadhaar Card?

Aadhaar Card is a widely recognized identity document provided to residents of India. It features a unique 12-digit identification number issued by the Unique Identification Authority of India (UIDAI), which serves as a reliable proof of identity for accessing numerous government and private sector services.


Along with personal details such as the individual's name, date of birth, gender, and address, Aadhaar securely stores biometric information, including fingerprints, iris scans, and a photograph, to enable accurate and secure identity verification.


Today, Aadhaar is widely used for opening bank accounts, applying for passports, filing income tax returns, receiving government subsidies, obtaining SIM cards, and accessing various financial and welfare schemes.

Unlike many other identification documents, Aadhaar remains valid throughout the lifetime of the holder. Residents can also update their personal information whenever required to ensure that the details remain accurate and current.
