Aadhaar is a 12-digit unique ID number given by the Indian government. It serves as proof of identity and address for services like banking, mobile connections, and government benefits.

2. How can I get an Aadhaar if I don’t have one?

Visit any Aadhaar enrollment center with documents like a birth certificate, PAN, or voter ID. Fill the form, give biometrics (photo, fingerprints, iris scan), and you’ll get your Aadhaar in 15-20 days.

3. What if I forget my Aadhaar number?

If your mobile number is linked, retrieve it via UIDAI’s website, mAadhaar app, or SMS (send "GETUID" to 1947). If not, visit a center with ID proof.

4. Can I download Aadhaar online?

Yes! Visit eaadhaar.uidai.gov.in, enter your Aadhaar number, and download the e-Aadhaar PDF. Use your birth year + name as the password (e.g., RAM1990).

5. How to update my mobile number in Aadhaar?

Go to an Aadhaar center, fill out the update form, submit ID proof, and pay ₹50. Your number will update in 5-7 days.

6. Is Aadhaar mandatory?

No, but it’s needed for many services like PAN, bank accounts, subsidies, and SIM cards. Some private companies may ask for it, too.

7. What if my Aadhaar card is lost?

No worries! Download e-Aadhaar online or visit a center to reprint it. Your Aadhaar number remains the same for life.

8. Can I change my name or address in Aadhaar?

Yes. Visit a center with proof (like a passport for name or an electricity bill for address) and submit an update request. Fees may apply.

9. Is Aadhaar linked to my bank account?

Only if you voluntarily linked it (for subsidies or KYC). Check with your bank or log in to Internet banking to see if it’s linked.

10. Is Aadhaar safe? Can someone misuse it?

Aadhaar has strong security. Never share OTPs or scans with strangers. Mask your Aadhaar (show only the last 4 digits) when sharing online.
