Introduction to Aadhaar Card

The Aadhaar Card is one of the most important identity documents in India. It is issued by the Unique Identification Authority of India (UIDAI) and contains a unique 12-digit number that serves as proof of identity and address for every resident of India. Over the years, Aadhaar has become an essential part of government schemes, banking services, taxation, and even daily verification processes.

In 2025, Aadhaar continues to play a central role in digital India initiatives, helping citizens access multiple services seamlessly.

Aadhaar is not just an identity card but also a digital platform that enables authentication across several services. It is linked with demographic details such as:

Name

Biometric Information (Fingerprint & Iris scan)

The UIDAI ensures that each Aadhaar number is unique and cannot be duplicated.
