Aadhaar and UIDAI

To create a strong and effective system to fight and eliminate fake/duplicate identities in a cost-effective way, the Government of India introduced the Aadhaar Card. Every Aadhaar Card contains an Aadhar Number or Aadhar ID which is unique to every resident of India and is issued to every resident of India.

To make the process of Aadhar issuing smooth and easy, the government established the Unique Identification Authority of India. UIDAI is responsible for all of the matters related to Aadhaar including Aadhar issuing, Aadhar enrolment, and authentication, the establishment of Aadhar policy, procedure and system for issuing Aadhaar numbers to people, verify and authenticate people’s identity information and other related functions.

Functions of UIDAI

Aadhar acts as a Proof of Identity for people and the government is trying to link all the identity cards and accounts with Aadhaar including PAN, Voter ID, Passport, Driving License, Bank Accounts, etc.

Government is trying to do all this in a step-by-step manner and currently, it is mandatory to link both the PAN and bank accounts with the Aadhar Card and the deadline for linking Aadhar to PAN is September 30th, 2019. All the PAN Cards not linked within that time frame will be deactivated!
