From document verification to authentication, the process can differ depending on the information you want to update. Here is what Aadhaar holders need to know.

Aadhaar Date of Birth Update: What Are the Rules?

The Unique Identification Authority of India, or UIDAI , has clarified that there is no fixed limit on updating the Date of Birth (DoB) in Aadhaar. However, if the date of birth has already been changed once, any further request is subject to a strict verification process.


To request an Aadhaar DOB update , you may need to:

  1. Visit an Aadhaar Enrolment or Update Centre.
  2. Submit the required supporting documents.
  3. Complete the necessary biometric verification.
Online options may be available in certain situations, but supporting documents and their verification remain important.


Check the Required Documents Before Applying

Before starting an Aadhaar update , it is important to check the accepted documents and applicable procedures. UIDAI provides a detailed list of approved documents and standard operating procedures.

Having the correct documents ready can help reduce the possibility of delays or rejection during the update process.

Aadhaar Address Update : What You Need to Know

Aadhaar holders can update their address using the available Aadhaar services, subject to the applicable process and requirements. A valid Proof of Address (PoA) document is required.

The process described includes selecting the address update option, entering the new address, uploading the required proof, completing face authentication and paying the applicable processing fee.


Examples of address proof can include documents such as a utility bill, bank statement, passport or rental agreement, subject to the applicable requirements.

After submitting the request, an Update Request Number (URN) may be provided to track its status.

Aadhaar Mobile Number Update

Your registered mobile number is important because it can be used for OTP verification and various digital services. If your mobile number has changed, updating the Aadhaar-linked number can help ensure you receive important authentication messages.

The Aadhaar app process described involves logging in with your Aadhaar details and registered mobile number, setting a six-digit PIN and selecting Update My Aadhaar.

You can then select the mobile number update option, verify the existing and new mobile numbers through OTPs, and complete face authentication. The applicable processing fee is then paid to submit the request.


Keep Your Aadhaar Details Updated

Whether you need an Aadhaar DOB update, address change or mobile number update, check the latest UIDAI requirements before submitting your request. Keep the necessary documents ready and enter your information carefully to avoid unnecessary delays.
