How to Update Your Aadhaar Details Online and Stay Safe Doing It

What can you update online versus in person?

UIDAI, the authority that manages Aadhaar, allows certain demographic updates through its self-service portal myaadhaar.uidai.gov.in. Here is a quick reference:

• Can be updated online: Address, Name, Date of Birth (limited to once, with supporting proof), Gender, Email address
• Requires Aadhaar Enrolment Centre visit: Mobile number, Biometrics (fingerprints and iris scan)

For mobile number updates, locate your nearest centre using the centre-locator at appointments.uidai.gov.in. The fee at the centre is Rs 100 including GST.

Documents you will need

Each field update requires a specific proof document. Here are the most commonly needed ones:

• Address update: Bank statement or passbook (last 3 months), utility bill (electricity/water/gas, last 3 months), rental agreement, or any government-issued letter with your address
• Name update: PAN card, passport, driving licence, voter ID, or any government certificate showing the correct legal name
• Date of birth update: Birth certificate, SSLC/10th marksheet, passport (only documents with your printed DoB are accepted)
• Gender update: No document required — declaration is sufficient
• Email update: No document required — your email address is verified by OTP

Documents must be scanned as clear, uncompressed JPEG or PDF files under 2 MB each. Handwritten documents are not accepted.

Step-by-step: updating address online

Address is the most commonly updated field. The steps below cover address; the process for other fields is similar.

Common problems

• OTP not received: This usually means your mobile number is not linked to Aadhaar, or the number is inactive. In this case, you must visit an Aadhaar Enrolment Centre to update your mobile number first, then return online.
• Update request rejected due to document mismatch: UIDAI’s system checks the address or name text against your uploaded document using OCR. If your bank statement shows Bengaluru but you typed Bangalore, it may reject the request. Use exactly the spelling shown in your document.
• Payment made but URN not received: Wait up to 2 hours. If still not received, contact UIDAI at 1947 (toll-free, available 7 AM to 11 PM) with your payment transaction ID.
• Portal showing Update limit reached for name or DoB: UIDAI currently allows name updates a maximum of two times and date-of-birth updates only once over your lifetime. If you have reached the limit, a visit to an Enrolment Centre with an affidavit may be required.

How to protect yourself from Aadhaar scams

UIDAI has confirmed that it never calls, messages, or emails residents asking for an OTP, Aadhaar number, or bank details. If you receive such a call, disconnect immediately. Common scam patterns to watch for:

• Callers claiming your Aadhaar is suspended or blocked and asking you to share an OTP to reactivate it
• WhatsApp messages with a link to an unofficial Aadhaar update portal
• Local agents at photocopy shops who offer to update Aadhaar for Rs 300-500 — if they insist on your OTP, they are committing identity theft

You can lock your Aadhaar biometrics at any time from the myAadhaar portal under Lock/Unlock Biometrics — this prevents anyone from using your fingerprints at a banking kiosk without your permission.
