If you moved abroad a while ago, there’s a good chance your Aadhaar card still has your old Indian mobile number and an address you haven’t lived at in years. That’s usually fine — until you need Aadhaar for something that actually matters: opening an NRE account, completing KYC for an investment, or closing a property deal in India. Suddenly an out-of-date Aadhaar becomes a real problem.

This is a plain-language guide to what you can actually fix from wherever you are right now, and what genuinely requires a trip back to India. It’s based on UIDAI’s own published rules, not forum guesses.

Key Takeaways

• Address update is fully online, through the myAadhaar portal, for a ₹50 fee, with a proof-of-address document upload.
• Mobile number update has no online option at all. It requires an in-person visit to an Aadhaar Seva Kendra in India.
• If you’ve lost access to the mobile number linked to your Aadhaar, you can’t log into most online services either — which usually means an in-person visit is unavoidable.
• Name, date of birth, and gender corrections all require an in-person visit too, and each can only be done a limited number of times in your lifetime.
• The mAadhaar app lets you view your Aadhaar, lock or unlock your biometrics, and generate an offline e-KYC file from anywhere — no visit needed for any of that.

This is general information based on UIDAI’s published rules as of July 2026. Aadhaar rules do change from time to time — always confirm current requirements on the official UIDAI website (uidai.gov.in) or by calling 1947 before you act.

What You Can Actually Update From Abroad, Right Now

Only one demographic detail can be changed fully online today: your address.

Through the myAadhaar portal, you can submit an address update from anywhere in the world. You’ll need to log in with your Aadhaar number and an OTP sent to your registered mobile number, then upload a clear, colour scan of a proof-of-address document — a passport, utility bill, or bank statement, for example. The fee is ₹50, including GST. Once submitted, you get a Service Request Number (SRN) to track the request, and you can cancel it for a refund any time before it’s picked up for processing.

A few other things are also fully self-service, with no visit required:

• Lock or unlock your biometrics through the mAadhaar app — useful if you’re worried about misuse while you’re not actively using your Aadhaar.
• Download your e-Aadhaar or check your Aadhaar PVC card status online.
• Generate a Virtual ID (VID) if you’d rather not share your actual Aadhaar number for a particular purpose.

What Needs an In-Person Visit to India

Everything else does — and this list surprises most NRIs:

• Mobile number update or registration. There is no online path for this at all. UIDAI’s own guidance is direct: if you need to change or add the mobile number linked to your Aadhaar, you must visit an Aadhaar Seva Kendra in person.
• Name correction or change — limited to twice in your lifetime.
• Date of birth correction — limited to once in your lifetime, and only with proof.
• Gender correction — limited to once in your lifetime.
• Biometric updates (photo, fingerprints, iris scan).
• First-time Aadhaar enrolment. There’s no way to enrol for Aadhaar for the first time without visiting an enrolment centre in person — your biometrics have to be captured physically.

The Catch Most NRIs Run Into: You Need Your Registered Mobile Number to Do Anything Online

Here’s the problem that catches people out. Even the one thing you can do online — updating your address — requires you to log in with an OTP sent to your Aadhaar-registered mobile number. If that’s an old Indian SIM you no longer have, you can’t get the OTP, which means you can’t log in, which means even the online option is closed to you. At that point, an in-person visit is the only way forward, specifically to get the mobile number updated first.

Two practical ways NRIs avoid this trap:

• Keep an Indian number minimally active. Prepaid plans from Jio, Airtel, and others offer long-validity recharge packs that keep a SIM alive (and able to receive SMS) for months at a time, even without regular top-ups, and many support incoming SMS while on international roaming.
• Use a trusted family member’s number as your registered mobile, and coordinate with them over WhatsApp or a call whenever you need an OTP relayed to you. This works, but it does mean someone else can technically request Aadhaar OTPs on your behalf, so only do this with someone you fully trust.
