Aadhaar is a unique 12–digit identification number that citizens or passport holders of India may voluntarily obtain on the basis of their biometric and demographic data. The information is gathered by the Unique Indian Identification Authority (UIDAI), a statutory authority created by the Government of India in January 2009 under the jurisdiction of the Ministry of Electronics and Information Technology, pursuant to the provisions of the Aadhaar Act, 2016.
Aadhaar is the largest biometric identification system in the world. Perceived a proof of residence and not a proof of citizenship, Aadhaar itself does not grant any domicile privileges in India. The Home Ministry explained in June 2017 that Aadhaar is not a valid identification card for Indians who fly to Nepal and Bhutan.
The UIDAI had functioned as an attaché of the Planning Commission (now NITI Aayog) since 28 January 2009 before the Law was enacted. A money bill to offer Aadhaar legal backing was introduced in Parliament on 3 March 2016. The Aadhaar Act, 2016, was adopted in the Lok Sabha on 11 March 2016.
How to Register for Aadhar Card
Before applying for an Aadhaar, the first step a applicant should keep in mind is to have all the documents required for the Aadhaar card ready while visiting the enrolment centre. The Aadhaar card application process is the same for all Indian nationals including minors and senior citizens.
At the time of enrolment they only have to provide relevant documents. Here’s how the person can do it:

- The Acknowledgement slip should be kept safely till you get your Aadhaar card.
Get Your e–Aadhar
Once all the documents and biometric data required for the Aadhaar card are submitted, sending the Aadhaar card to your residential address can take up to 90 days, i.e. 3 months. The card will be sent via India Post, and it may take more than 90 days to reach the respective card holder due to the high number of people applying for the Aadhaar card.
