How to Apply for Aadhaar Card Online – A Step-by-Step Guide

Aadhaar has become a fundamental part of every Indian citizen’s identity. Introduced by the Unique Identification Authority of India (UIDAI), it provides a unique 12-digit identification number based on biometric and demographic data. Whether you’re opening a bank account, filing income tax, or applying for government subsidies, Aadhaar plays a crucial role.

Although Aadhaar registration itself is not completely online (due to the requirement of biometric data), UIDAI allows users to initiate the process online by booking appointments and filling out pre-enrollment details. This guide explains how to apply for an Aadhaar card through the official channels, what documents are required, and how to track or download your Aadhaar once issued.

What Is Aadhaar?

Aadhaar is a government-issued identity number designed to provide a single, verifiable identity to every resident of India. It includes:

A unique 12-digit number

Name, gender, date of birth

Biometric data (fingerprints and iris scan)

Address and photograph

Aadhaar is not proof of citizenship but serves as valid identity and address proof for a variety of services.

Fill out the application form online

This saves time and avoids long queues at centers.
