What Is Aadhaar?
Aadhaar is a 12-digit unique identity number issued to Indian residents by the Unique Identification Authority of India (UIDAI). It is based on biometric and demographic data, including:
- Fingerprint
- Iris scan
- Photograph
- Name, date of birth, gender, address
Aadhaar is not a proof of citizenship, but it is the most widely accepted proof of identity and address in India.
It is used for:
- Opening bank accounts
- Applying for PAN card
- Availing government subsidies (LPG, food rations)
- Filing income tax returns
- Boarding flights and trains
- Mobile SIM verification
Why Is Aadhaar Slot Booking Required?
Before 2023, people could walk into any Aadhaar center and wait in long queues. This led to:
- Overcrowding
- Wasted time
- Risk of data theft
- Inefficient service delivery
To solve these issues, UIDAI made online slot booking mandatory in 2023. Now, you cannot get Aadhaar services without a prior appointment.
Benefits of Aadhaar Slot Booking:
✅ No long queues – You arrive at your scheduled time
