The Complete Guide to Aadhaar: Eligibility, Downloading, and Updating
In today’s digital India, the Aadhaar card has become a cornerstone identification document that connects citizens to essential services and benefits. This comprehensive guide explores who is eligible for an Aadhaar card, how to obtain your digital Aadhaar, and the procedures for keeping your information current.
Understanding Aadhaar
Aadhaar is a 12-digit unique identification number issued by the Unique Identification Authority of India (UIDAI). Unlike traditional identity documents, Aadhaar uses both demographic information and biometric data (fingerprints, iris scans, and facial photographs) to create a secure, unique identity for Indian residents.
Eligibility for Aadhaar
Residents of India
The fundamental eligibility criterion for Aadhaar is residency, not citizenship. Any individual residing in India for at least 182 days in the 12 months preceding their application qualifies for Aadhaar registration. This includes:
- All citizens of India, regardless of age
- Newborns and infants (who receive a special Baal Aadhaar)
- Senior citizens
- Persons with disabilities
Non-Resident Indians (NRIs)
NRIs can also obtain an Aadhaar card if they meet the residency requirement of 182 days in India during the preceding year. They must present their valid Indian passport as proof of identity during enrollment.
Foreign Nationals
Certain categories of foreign nationals residing in India can apply for Aadhaar:
- OCI (Overseas Citizen of India) cardholders with valid foreign passports
- Individuals with Long Term Visa (LTV) documents
- Nationals of Nepal and Bhutan
- Other foreign residents who have lived in India for at least 182 days
Required Documents for Aadhaar Enrollment
To enroll for Aadhaar, applicants must provide:
- Proof of Identity (POI): Passport, Voter ID, PAN card, Driving License, etc.
- Proof of Address (POA): Utility bills, Bank statements, Rental agreements, etc.
- Proof of Date of Birth (DOB): Birth certificate, School certificate, Passport, etc.
For children below 5 years, a birth certificate and the Aadhaar cards of either parent are required. Biometric information for these children is not collected until they reach 5 years of age.
Downloading Your Aadhaar Card
The digital version of your Aadhaar card (e-Aadhaar) has the same legal validity as the physical card. Here are various methods to download your e-Aadhaar:
