Aadhar 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. Aadhar letter received via India Post and e-Aadhar downloaded from UIDAI website are equally valid.

Any individual, irrespective of age and gender, who is a resident in India and satisfies the verification process laid down by the UIDAI can enrol for Aadhar.

Each individual needs to enroll only once which is free of cost.

Each Aadhar number will be unique to an individual and will remain valid for life. Aadhar number will help you provide access to services like banking, mobile phone connections and other Govt and Non-Govt services in due course.

Some other information about Aadhar:

Aadhar will be:

  • Easily verifiable in an online, cost-effective way
  • Unique and robust enough to eliminate the large number of duplicate and fake identities in government and private databases
  • A random number generated, devoid of any classification based on caste, creed, religion and geography

The brand name of the Unique Identification number (UID) will be Aadhar. The name and logo for the unique numbers to be issued by the UIDAI have been developed keeping in mind the transformational potential of the program.

Together, they communicate the essence and spirit of the UIDAI’s mandate to people across the country.

The UIDAI’s mandate is to issue every resident a unique identification number linked to the resident’s demographic and biometric information, which they can use to identify themselves anywhere in India, and to access a host of benefits and services.

As Mr. Nandan Nilekani, Ex Chairman of the UIDAI notes, “The name Aadhar communicates the fundamental role of the number issued by the UIDAI the number as a universal identity infrastructure, a foundation over which public and private agencies can build services and applications that benefit residents across India.”

  • Aadhar’s guarantee of unique and centralised, online identity verification would be the basis for building these multiple services and applications, and facilitating greater connectivity to markets.
  • Aadhar would also give any resident the ability to access these services and resources, anytime, anywhere in the country.
  • Aadhar can for example, provide the identity infrastructure for ensuring financial inclusion across the country – banks can link the unique number to a bank account for every resident, and use the online identity authentication to allow residents to access the account from anywhere in the country.
  • Aadhar would also be a foundation for the effective enforcement of individual rights. A clear registration and recognition of the individual’s identity with the state is necessary to implement their rights –to employment, education, food, etc. The number, by ensuring such registration and recognition of individuals, would help the state deliver these rights.
