What is Aadhaar Card?
Aadhaar is a 12-digit unique identity number issued by UIDAI under the Ministry of Electronics and Information Technology (MeitY), Government of India. It was introduced under the Aadhaar (Targeted Delivery of Financial and Other Subsidies, Benefits and Services) Act, 2016.
Each Aadhaar number is linked to the individual’s biometric data — fingerprints, iris scans, and a photograph — making it virtually impossible to duplicate or forge. This makes Aadhaar the gold standard for identity verification in India.

UIDAI provides a powerful security feature — you can lock your biometrics to prevent anyone from authenticating using your fingerprints or iris scans, even if they have your Aadhaar number. This protects against identity theft and fraudulent authentication.
- Visit myaadhaar.uidai.gov.in → “Lock/Unlock Biometrics”
- Enter your 12-digit Aadhaar number and security code
- Request an OTP on your registered mobile
- Enter OTP and click “Lock Biometrics” or “Unlock Biometrics“
- Confirmation appears instantly — biometrics are locked/unlocked immediately
🔒 Best Practice: Keep your biometrics locked at all times and only unlock temporarily when you need to use biometric authentication (e.g., at a bank or government office). Re-lock immediately after use.

Frequently Asked Questions (FAQ) – Aadhaar Card 2026
Q1. What is Aadhaar card and what is its purpose?
Aadhaar is a 12-digit unique identification number issued by UIDAI (Unique Identification Authority of India) to every Indian resident. It serves as proof of identity and address for accessing government services, subsidies, bank accounts, SIM cards, passport applications, and a wide range of digital services in India. With over 1.38 billion enrolments, it is the world’s largest biometric ID system.
Q2. What documents are required for Aadhaar card enrolment?
You need one Proof of Identity (POI) and one Proof of Address (POA) from the UIDAI-approved list. Acceptable documents include Passport, PAN Card, Voter ID, Driving Licence, Bank Passbook, Electricity Bill, Ration Card, and NREGS Job Card. For children under 5, a birth certificate and a parent’s Aadhaar is sufficient.
Q3. Can NRIs apply for Aadhaar card?
No. Aadhaar is issued only to residents of India. NRIs (Non-Resident Indians) who do not permanently reside in India are not eligible for Aadhaar enrolment. Only individuals who are Indian residents — regardless of citizenship — can obtain Aadhaar.
Q4. What is e-Aadhaar and is it valid as proof of identity?
e-Aadhaar is the official digitally signed electronic version of your Aadhaar card, downloadable as a password-protected PDF from myaadhaar.uidai.gov.in. It is legally valid as proof of identity and address — exactly equivalent to the physical Aadhaar card — and is accepted by all government offices, banks, airports, and service providers across India.
Q5. Is it mandatory to link Aadhaar with bank account?
As per the Supreme Court’s ruling, it is not universally mandatory to link Aadhaar with a private bank account. However, it is mandatory for receiving government subsidies and Direct Benefit Transfer (DBT) amounts — including PM-KISAN, LPG subsidy, MGNREGS wages, and scholarships. Farmers and government benefit recipients must link their Aadhaar with their bank account to receive these payments.
Q6. How can I update my mobile number in Aadhaar?
Mobile number update in Aadhaar can only be done offline — by visiting the nearest Aadhaar Seva Kendra in person. There is no online facility for mobile number update as UIDAI requires in-person biometric verification for this change. The fee is ₹50. Book an appointment at uidai.gov.in before visiting.
Q7. What is the password to open the e-Aadhaar PDF file?
The password to open e-Aadhaar PDF is the combination of the first 4 letters of your name in UPPERCASE followed by your 4-digit birth year. Example: if your name is Sunita and you were born in 2000, the password is SUNI2000. For names shorter than 4 letters, use the full name in uppercase followed by birth year.
Q8. Why should I lock my Aadhaar biometrics?
Locking your Aadhaar biometrics prevents anyone — even if they have your Aadhaar number — from authenticating using your fingerprints or iris scans without your permission. This protects you from identity fraud, unauthorised subsidy withdrawals, and SIM cloning. UIDAI recommends keeping biometrics locked at all times and unlocking only temporarily when you need to use biometric authentication in person.
