In India, the Aadhaar Card has become the most widely used identity document for citizens. It serves as a proof of identity and address for various public and private services — from bank accounts and SIM cards to government benefits and tax filings. Given its importance, knowing how to apply for an Aadhaar card and how to update key details like name, address, phone number, mobile number, and age is essential.
What Is Aadhaar?
Aadhaar is a 12-digit unique identity number issued by the Government of India to Indian residents based on their biometric and demographic data.
It includes:
- Name
- Photo
- Address
- Date of Birth
- Gender
- Biometrics (Fingerprints & Iris Scan)
Aadhaar is linked with several government and private services and is often used for verification, authentication, subsidies, and digital identity.
