How to Update Aadhaar Address or Phone Number

Updating your Aadhaar address or mobile number is important because it keeps your identity details consistent across banks, SIM cards, government services, and travel bookings. The good news is that UIDAI has made the process straightforward if you have the right documents and follow the correct steps. In the following sections, you’ll find what you need to keep ready and a simple, step-by-step guide to update your Aadhaar details.

Documents Needed to Update Aadhaar Details Online

To update your Aadhaar address online, you’ll need a valid Proof of Address (PoA) document in your name. Commonly accepted documents include a Passport, Voter ID, Driving Licence, bank passbook, ration card, or recent utility bills—provided they match UIDAI’s accepted list. Make sure the document is clear, readable, and up to date so your request doesn’t get rejected during verification.

If your address proof is not directly in your name (for example, it’s in a family member’s name), you may still be able to update your address using alternative options like a Head of Family (HoF) declaration, where applicable. In such cases, additional relationship proof may be needed depending on the method used. It’s a good idea to check the latest accepted documents on the official UIDAI portal before you apply, because the list can change.

For updating your mobile number (phone number), note an important point: UIDAI typically requires mobile number updates to be done at an Aadhaar Enrolment/Update Centre, not fully online. This is because your biometric verification is usually required. So while you can prepare for the process online (finding the nearest centre, checking fees, and understanding the steps), you should keep your Aadhaar number and identity details ready for in-person verification.

Step-by-Step: Change Aadhaar Address or Mobile Number

1) How to change Aadhaar address online (via UIDAI portal)

First, visit the official UIDAI website and look for the Aadhaar update option meant for address update. Log in using your Aadhaar number and OTP received on your registered mobile number. Once you’re inside the update section, select the “Address” field and enter your new address exactly as you want it to appear on your Aadhaar (including spelling, PIN code, state, and any landmarks).

Next, upload a scanned copy or clear image/PDF of your Proof of Address document. Ensure the file meets the size and format rules shown on the portal; unclear images, cut-off pages, or mismatched details are common reasons for rejection. Carefully review the preview before submitting, because even small errors (like a wrong PIN code or misspelled locality) can create problems later.

After submission, you will receive an Update Request Number (URN). Save it to track the status of your request. Once the update is approved, you can download your updated e-Aadhaar online. In many cases, UIDAI also sends an SMS confirmation when the change is processed, and a printed Aadhaar letter may be delivered if you choose that option.

2) How to change Aadhaar mobile number (usually at an Update Centre)

To update or change your Aadhaar phone number, locate a nearby Aadhaar Enrolment/Update Centre using the UIDAI “Locate an Enrolment Center” tool. Visit the centre with your Aadhaar number (or a copy of Aadhaar/e-Aadhaar). You’ll fill out an Aadhaar update form and provide the new mobile number you want to register.

At the centre, the operator will verify your identity using biometric authentication (fingerprint/iris), which is why this process is generally not available fully online. After verification, you will be given an acknowledgement slip containing an Update Request Number (URN). Keep this safe until the change reflects in UIDAI records.

Once your new number is updated, you can start receiving OTPs on it for Aadhaar services such as downloading e-Aadhaar, using Aadhaar-based verification, and accessing other linked services. If you’re changing numbers because the old one is lost or inactive, this update is especially important—without a registered number, many online Aadhaar services become difficult to use.

3) Tips to avoid delays and rejections

For address updates, the most important factor is document accuracy. Your entered address should align with your Proof of Address document; if the document shows “Road” and you enter “Rd,” or the house number differs, it can sometimes trigger a mismatch. Also, upload a complete document (all relevant pages) and ensure the image is sharp, well-lit, and not cropped.

For mobile number updates, double-check the number before submitting at the centre, because a single digit mistake can cause major inconvenience later. Also, remember that an OTP will go to the newly registered number for many Aadhaar services—so choose a number that you’ll keep active for the long term.

Finally, track your URN status online if the update seems delayed. If your request is rejected, the portal usually shows a reason, and you can reapply with corrected information or better documentation. Following the correct steps from the start saves time and reduces the need for repeat visits or submissions.

Keeping your Aadhaar address and mobile number updated helps you avoid service disruptions and makes verification smoother across many essential tasks in India. Address changes can often be done online with valid proof, while mobile number updates generally require a visit to an Aadhaar Update Centre for biometric verification. Use the document checklist, follow the steps carefully, and keep your URN handy to track progress until the update is completed.
