Aadhaar Update Guide: How to Change Address, Mobile Number, Name and Date of Birth

Aadhaar is the base identity document for banking, tax, subsidies and many services, so wrong details can cause real problems with KYC, PAN linking and OTP delivery. UIDAI, the authority that issues Aadhaar, allows you to update most details. Some updates can be done online from home, while others need a visit to an enrolment centre because they involve biometrics or verification. This guide sets out what can be done where.

What you can update, and how

UIDAI revises its rules and facilities over time, so check the current options on the official website before you start.

Updating your address online

1. Go to the official myAadhaar portal and log in with your Aadhaar number and an OTP sent to your registered mobile. This is why keeping your mobile linked matters.
2. Choose the address update option and enter the new address.
3. Upload a scanned copy of a valid proof of address in the new name and address, such as a passport, bank statement, utility bill, rent agreement or other accepted document.
4. Review the details and submit. You get an update request number (URN).
5. Track the status with the URN, and download the updated Aadhaar once it is approved.

If you do not have any document in your name, a head of family option or an address verification letter route is available in some cases, where a family member or a verifier consents. Use only the procedures on the official site.

Updating details at an enrolment centre

1. Find a centre using the "locate an enrolment centre" tool on the UIDAI website or at a bank or post office that offers Aadhaar services.
2. Fill in the correction form, carry your original Aadhaar and original supporting documents, and expect a biometric check.
3. Pay the fee. The fee for biometric or demographic updates at a centre is a small fixed amount, such as ₹50 plus GST at the time of writing, and different for new enrolment, which is free.
4. Collect the acknowledgement slip with the update request number and track it online.

Updating documents after ten years

UIDAI encourages everyone whose Aadhaar was issued more than ten years ago and never updated to submit proof of identity and address once, so that records are current. The online document update facility has been offered free for a limited period from time to time, so check whether the free window is still on. After that a fee applies.

Children

For children, biometrics are not captured until the age of five, so a "Baal Aadhaar" is issued initially. The child's biometrics must be updated when they turn five and again at fifteen, and the updates are free for children within the age bands. Missing them can lead to the Aadhaar being deactivated, which affects school and scholarship services, so do not skip them.

Limits on changes

• Name, date of birth and gender can only be changed a limited number of times.
• Any change must be supported by an official document.
• Some changes need the exact spelling that appears on your other documents, so keep identity documents consistent.

Why your Aadhaar and mobile must match

Many services send an OTP to your Aadhaar-linked number. If your number changed, update it at a centre so you can use the online services described here. Linking also applies to PAN and bank accounts, so use the same name and date of birth. See our guide to applying for a PAN for the linking steps.

Staying safe

• Use only the official UIDAI website and app. Fake websites and agents ask for large fees or personal data.
• Do not share OTPs or your full Aadhaar number with strangers. Use a masked Aadhaar where an organisation permits it.
• Lock your biometrics on the myAadhaar portal when you are not using biometric authentication, and unlock only when you need to.
• Check the authentication history on the portal for unknown use.

This guide is for general information and processes change. Always confirm the latest procedure, fees and accepted documents on the UIDAI website.
