Keeping the mobile number linked with Aadhaar updated is important because the registered number can be used for Aadhaar-related authentication and notifications. If you have changed your SIM, lost your previous number, or simply want to link a different number with your Aadhaar, you can now use the official Aadhaar App for mobile-number updating.
UIDAI has introduced mobile-number update functionality in its Aadhaar App. Depending on your existing Aadhaar-linked mobile number, the app may ask you to verify the old and new numbers through OTP, complete Face Authentication, and pay the applicable fee.
Can You Update the Aadhaar Mobile Number Online?
Yes. As per the latest UIDAI information, the official Aadhaar App provides a facility to update the mobile number without visiting an Aadhaar Seva Kendra in supported cases. The app currently provides services including mobile-number and address updates, Aadhaar download, authentication history and request tracking.
This is different from the older Aadhaar online-update process, under which mobile-number updates were generally handled at an Aadhaar Enrolment or Update Centre.
Steps to Update New Mobile Number in Aadhaar Online
Follow these steps to request a mobile-number update through the official Aadhaar App.
Step 1: Download the Official Aadhaar App
Install the official Aadhaar App on your Android or iOS smartphone.
Make sure you download the genuine app provided by UIDAI rather than an unofficial Aadhaar-related application.
Step 2: Register on the Aadhaar App
Open the app and select your preferred language.
Enter your Aadhaar number and agree to the applicable terms and privacy conditions. You will then need to select the SIM card and complete Face Authentication.
After successful registration, you can create a 6-digit PIN to secure access to the application.
Step 3: Open the Mobile Number Update Service
After logging into the Aadhaar App, look for the service related to Mobile Number Update.
Select it and enter the new mobile number that you want to link with your Aadhaar.
Step 4: Verify the Mobile Number
The verification process can depend on whether you are already registered on the Aadhaar App with the mobile number currently linked to Aadhaar.

According to UIDAI:
- If the Aadhaar App is registered using the same mobile number already registered with Aadhaar, you need to verify the new mobile number through OTP.
- If the Aadhaar App is registered using a different mobile number, you may need to verify both the existing Aadhaar-linked mobile number and the new mobile number through OTP.
Step 5: Complete Face Authentication
The next step is Face Authentication.
Follow the instructions displayed by the Aadhaar App and position your face correctly for authentication. The purpose of this step is to verify the Aadhaar number holder before the mobile-number update request is submitted.

Step 6: Pay the Applicable Fee
After completing the required verification, you will be asked to pay the prescribed charge for the update.
The applicable fee can be checked through the official UIDAI service before completing the transaction.
Step 7: Submit the Update Request
Once OTP verification, Face Authentication and payment have been completed, submit the request.
Keep the request or transaction details shown by the app for future reference.
Step 8: Track Your Aadhaar Update
UIDAI provides facilities for tracking Aadhaar service requests. The Aadhaar App itself also includes a Track my request facility.
Remember that submission of a request does not automatically mean that the update has been approved. UIDAI processes update requests after verification and validation.

What If You Have Lost Your Old Mobile Number?
If your old Aadhaar-registered mobile number is no longer available, the process can be different.
UIDAI’s Aadhaar information states that a person who has lost or does not possess the mobile number registered with Aadhaar can submit a mobile-number update request at an Aadhaar Enrolment Centre. The older UIDAI FAQ also states that no old mobile number or document is required for this centre-based mobile update.
Therefore, if the Aadhaar App asks for verification of your old number and you cannot access it, visiting an Aadhaar Enrolment/Update Centre may be necessary.
Can You Update Aadhaar Mobile Number From the MyAadhaar Website?
The traditional MyAadhaar online services have not historically allowed mobile-number updates through the website. UIDAI’s online-services information states that mobile-number updates can be carried out at an Aadhaar Enrolment Centre.
The newer Aadhaar App has introduced a separate mobile-number update facility. Therefore, users should not confuse the MyAadhaar website’s online update services with the new Aadhaar App-based mobile-number update service.
Do You Need Any Document to Change the Mobile Number?
For the app-based mobile-number update, UIDAI’s current instructions focus on OTP verification, Face Authentication and payment rather than uploading a supporting document for the mobile number itself.
If you update the mobile number through an Aadhaar Enrolment Centre, the centre will process the request according to the applicable UIDAI procedure.
How Long Does Aadhaar Mobile Number Update Take?
An Aadhaar update request is subject to UIDAI’s verification and validation process.
UIDAI states that normally 90% of Aadhaar update requests are completed within 30 days, although individual requests can take different amounts of time.
Therefore, users should not assume that the new number will become active immediately after submitting the request.
Will Your Aadhaar Number Change After Updating the Mobile Number?
No. Updating your mobile number does not change your 12-digit Aadhaar number.
The update changes the relevant information associated with your Aadhaar record, while the Aadhaar number remains the same.
Will You Receive a New Aadhaar Letter?
No new physical Aadhaar letter is normally sent simply because you have updated your mobile number.
UIDAI states that for mobile-number or email-ID updates, a notification is sent rather than a new Aadhaar letter.
Important Points Before Updating Your Aadhaar Mobile Number
Keep these points in mind before starting the process:
- Use the official Aadhaar App downloaded from the authorised app store.
- Enter the new mobile number carefully.
- Keep access to the required mobile number for OTP verification.
- Complete Face Authentication as instructed.
- If your old Aadhaar-linked number is unavailable, you may need to visit an Aadhaar Enrolment/Update Centre.
- Save your request or transaction details after submission.
- Check the status of the update instead of assuming that the request has already been approved.
- Never share Aadhaar OTPs or authentication details with unknown persons.
