  • Aadhaar refers to the 12-digit Unique Identification number (UID) issued by the Unique Identification Authority of India (UIDAI).
  • The UIDAI is a statutory authority. It was established on 12 July 2016 under the Aadhaar Act 2016 by the Government of India, under the Ministry of Electronics and Information Technology (MeitY).
  • The UIDAI is responsible for Aadhaar authentication, enrolment and ensuring security of identity information.
  • The UIDAI issued the first Aadhar number on 29 September 2010.
    The vision of UIDAI is to empower Indian residents with a unique identity and a digital platform to authenticate anywhere and at any time.
  • The Aadhaar number for each individual enables efficient delivery and monitoring of various programs and welfare schemes of the Government.

Documents Required

  • UIDAI process accepts 18 Proof of Identity (PoI) and 33 Proof of Address (PoA) documents. These include Ration card, driving license, election photo ID card, passport and photo IDs such as PAN Card. Water, electricity and telephone bills from the last three months can also be submitted as address proof.
  • In case you do not have any of these documents, a Certificate of Identify with your photo, issued by Gazetted Officer/Tehsildar on letterhead is also accepted as PoI.
  • Similarly a Certificate of Address with your photo, issued by an MP/ MLA /Gazetted Officer/Tehsildar on letterhead or by Village Panchayat head /other equivalent authority (for rural areas) is accepted as valid PoA.
  • If an individual does not have valid documents he/she can still enroll if his/her name exists in family entitlement document. The Head of Family in entitlement document must be enrolled first with valid PoI and PoA documents. He can then introduce other family members who wish to enroll. UIDAI accepts 8 document types as Proof of Relationship.
    In absence of valid documents, a resident may also take the help of Introducers. Introducers are notified by the Registrar. They are present at all enrolment centers.


Since Aadhaar is a unique number that is linked to individual biometrics, no resident can have a duplicate number. Duplicate/ghost identities can thus be identified and eliminated. This will help prevent leakages in the system and benefits of various government schemes and policies will reach the targeted individuals. Aadhaar can also be used by residents to demand services, redress grievances and access up-to-date information about their entitlements. All this can be done directly from their mobile phone or from nearby kiosks.
