Aadhaar Card Complete Guide

Aadhaar is a 12-digit unique identification number issued by the Unique Identification Authority of India (UIDAI) to all Indian residents. It serves as proof of identity and address for accessing various government and private services across India.

The Aadhaar card contains basic demographic information (name, date of birth, gender, address) along with biometric data (fingerprints, iris scan, photograph). It's linked to an individual's unique biometric identity, making it one of the world's largest biometric identification systems.

The Aadhaar enrollment process involves visiting an authorized enrollment center with necessary documents for identity and address verification. Here's the complete step-by-step procedure:

• Step 1: Locate nearest Aadhaar Enrollment Center using UIDAI website or mAadhaar app
• Step 2: Carry original documents for identity proof and address proof
• Step 3: Fill the enrollment form with accurate personal details
• Step 4: Provide biometric data (fingerprints of all 10 fingers and iris scan)
• Step 5: Take photograph at the enrollment center
• Step 6: Verify all entered details on screen before submission
• Step 7: Receive acknowledgment slip with Enrollment ID (EID)
