Aadhaar mobile number update online through the official app and offline at an authorised centre

How to Update Mobile Number in Aadhaar Online or Offline

Your mobile number linked to Aadhaar is important for receiving OTPs and accessing various Aadhaar-related services. If you have changed your SIM card, lost your old number, or want to register a new number, you should check the current process provided by the Unique Identification Authority of India (UIDAI).

The good news is that the process has changed. UIDAI’s official Aadhaar app now provides a mobile-number update facility for eligible users. However, not everyone can complete the process through the app. Some people must visit an authorised Aadhaar centre, particularly if they no longer have access to their old registered number or are registering a mobile number for the first time.

This guide explains the Aadhaar mobile number update process, online and offline options, applicable charges, documents, verification steps, and how to check the status of your request.

Why Is Your Mobile Number Linked to Aadhaar Important?

Your registered mobile number helps you receive OTPs and access services that require mobile verification. If your old number is inactive or belongs to someone else, you may face difficulty using services that depend on that number.

You may need an Aadhaar mobile number update if:

You have changed your mobile network or phone number.
Your old SIM card has been lost or damaged.
Your old mobile number has been disconnected.
You want to register a new number with Aadhaar.
You cannot receive OTPs on the number currently registered.
You need to use Aadhaar-related digital services that require mobile verification.

Before starting an Aadhaar mobile number update, check whether you can still access the old registered number. This matters because the verification process through the official app depends on your circumstances.

Can You Update Your Aadhaar Mobile Number Online in 2026?

Yes, in eligible cases. UIDAI’s current Aadhaar app FAQ explains how users can update their mobile number through the official app. Depending on whether the app is registered with the old Aadhaar-linked number, you may need to verify the new number or both the old and new numbers using OTPs, complete face authentication, and pay the prescribed charge.

However, the app is not a universal solution for every applicant.

You generally need to visit an authorised centre if:

You do not have access to your old registered mobile number.
No mobile number has ever been registered with your Aadhaar.
The app cannot complete the required verification.
UIDAI directs you to an Aadhaar centre for your particular case.

The Aadhaar mobile number update process therefore depends on your existing registration and your ability to complete the required authentication.

Use the official UIDAI website, uidai.gov.in, to find current instructions and links to official Aadhaar services. Avoid unofficial apps or websites that ask for sensitive information while claiming to update Aadhaar instantly.

Method 1: Aadhaar Mobile Number Update Through the Official App

UIDAI’s official Aadhaar app includes a facility for updating a mobile number without visiting an Aadhaar Seva Kendra in eligible cases. The app’s current FAQ describes different verification steps depending on which number is registered with the app.

Follow these steps.

Step 1: Install or open the official Aadhaar app

Find the official Aadhaar app through a trusted app store and verify the publisher before installing it. You can start from UIDAI’s official website if you are unsure which app is genuine.

Do not enter your Aadhaar details into an unfamiliar app that claims to provide the same service.

Step 2: Register or log in

Open the app and follow the registration or login instructions. Complete any requested verification using the number and credentials associated with your current app registration.

The Aadhaar mobile number update process may differ depending on whether the number used to register the app is the same as the mobile number currently linked to Aadhaar.

Step 3: Open the mobile-number update service

Look for the mobile-number update option in the app’s services section. Read the displayed instructions before proceeding.

If the option is unavailable for your circumstances, check the app’s latest FAQ or use the authorised centre route.

Step 4: Enter the new mobile number

Enter the mobile number you want to link to Aadhaar. Check every digit before continuing because an incorrect number can delay the process.

Step 5: Complete OTP verification

UIDAI describes different cases:

If the app is registered with the same number currently linked to Aadhaar, you must verify the new number with an OTP.
If the app is registered with a different number from the one currently linked to Aadhaar, the app may require OTP verification for both the old registered number and the new number.

Follow the exact verification instructions shown in your app.

Step 6: Complete face authentication

The app’s documented process includes face authentication. Follow the instructions on your screen and make sure your face is clearly visible in suitable lighting.

Do not attempt to bypass the verification step or use another person’s identity to complete an Aadhaar mobile number update.

Step 7: Pay the prescribed charge

The official app FAQ says that the prescribed charges apply to mobile-number updates through the app. Check the amount displayed by the official service before making payment.

Avoid paying a separate, unofficial agent fee for an online process you can complete yourself.

Step 8: Save the request details

After submitting the request, save the acknowledgement or request reference displayed by the app. Use the available tracking facility to follow the request.

The app process is useful when your situation meets the required verification conditions. If verification fails or the app tells you to visit a centre, use the offline method described below.

Method 2: Aadhaar Mobile Number Update Offline at an Aadhaar Centre

If you cannot access the old registered number, or if you are registering a number for the first time, visiting an authorised centre is the appropriate route according to UIDAI’s guidance.

Step 1: Find an authorised Aadhaar centre

Use the official Bhuvan Aadhaar portal to locate a nearby enrolment or update centre.

You can also visit UIDAI’s Aadhaar Seva Kendra page for information about services and appointment booking.

Step 2: Check the available service

Before travelling, check whether the selected centre handles mobile-number updates. If an appointment facility is available for your chosen centre, you can book an appointment using the official process.

Step 3: Visit the centre

Go to the centre with your Aadhaar number or Aadhaar details available for identification. Follow the operator’s instructions.

UIDAI’s enrolment and update guidance states that a separate supporting document and the old mobile number are not required for a mobile-number update at an authorised centre. However, carry your Aadhaar details and any information the centre asks you to bring.

Step 4: Request the mobile-number update

Tell the operator that you want to change the registered mobile number or register one for the first time.

Check the new number carefully before confirming the request. The operator will follow the prescribed verification process.

Step 5: Complete biometric verification if required

The centre will authenticate the request according to UIDAI’s procedure. Follow the operator’s instructions for the required verification.

Do not leave the centre without confirming that the correct mobile number has been entered.

Step 6: Pay the applicable fee

UIDAI’s current Aadhaar Seva Kendra page lists a charge of ₹75 for a demographic update performed separately, which includes a mobile-number update. If the demographic update is carried out at the same time as a biometric update, the current listed charge is different. Check the latest official fee schedule and the amount displayed at the centre before paying.

Step 7: Collect the acknowledgement slip

After the request is submitted, keep the acknowledgement slip or update reference number. You may need it to check the status of your Aadhaar mobile number update.

The acknowledgement is important even if the operator tells you that the request has been submitted successfully. Submission does not mean the update has already been approved.

What Documents Are Required for an Aadhaar Mobile Number Update?

One useful feature of the standard mobile-number update process is that UIDAI’s guidance says you do not need to provide a separate supporting document or the old mobile number when updating your number at an authorised enrolment centre.

Before your Aadhaar mobile number update, consider keeping these details ready:

Your Aadhaar number or Aadhaar details.
The new mobile number you want to register.
Your acknowledgement or request number, if you are following up on an existing request.
Any additional information requested by the authorised centre or official app.

For an app-based update, you need to complete the required app registration, OTP and face-authentication steps. The specific verification requirements depend on your circumstances.

Do not confuse mobile-number updates with name, date-of-birth, or address corrections. Those services may have different supporting-document requirements.

How Much Does an Aadhaar Mobile Number Update Cost?

UIDAI publishes charges for Aadhaar update services. The current Aadhaar Seva Kendra information lists the following relevant demographic-update charges:

Service	Published charge
Separate demographic update, including mobile number	₹75
Demographic update carried out with a biometric update	Free under the listed combined-update rule

Source: UIDAI’s official Aadhaar Seva Kendra information.

The official app FAQ also says that the app-based mobile-number update requires payment of prescribed charges. Check the amount shown in the app before submitting your request.

For an Aadhaar mobile number update, always ask for the official fee and acknowledgement. Do not assume that a private agent’s service charge is a UIDAI fee.

How Long Does an Aadhaar Mobile Number Update Take?

Processing time can vary depending on verification and the status of the request. UIDAI’s enrolment and update page states that normally 90% of update requests are completed within 30 days. This is a general processing benchmark, not a guarantee that every request will finish within that period.

After submitting an Aadhaar mobile number update, keep your reference number and check the official tracking facility for the latest status.

If the request remains pending, follow the instructions on the UIDAI portal or contact UIDAI support. Do not submit repeated applications without first checking the status of the existing request.

How to Check Aadhaar Mobile Number Update Status

After submitting your request through the official app or at a centre, follow the tracking instructions provided by UIDAI.

Open the official UIDAI website or the Aadhaar app used for your request.
Find the update-status or request-tracking option.
Enter the acknowledgement or request reference details if requested.
Complete any required verification.
Read the current status and follow any instructions shown.

If you submitted your request at a centre, use the reference number printed on your acknowledgement slip. If you used the app, check the request-tracking option available there.

A submitted request may still be under verification. Your Aadhaar mobile number update should be treated as complete only when the official status confirms the update has been processed.

What If You Have Lost Your Old Mobile Number?

Losing access to your old number is a common reason for updating Aadhaar details. The appropriate process depends on whether you can complete the app’s required authentication.

UIDAI’s app FAQ states that people who cannot access their old registered mobile number should visit the nearest Aadhaar Seva Kendra or authorised enrolment and update centre.

In this situation:

Find an authorised Aadhaar centre through the Bhuvan Aadhaar portal.
Visit the centre and request a mobile-number update.
Complete the verification process.
Pay the applicable official charge.
Save your acknowledgement and track the request.

You do not need to keep an active old SIM just to request the standard update at an authorised centre. Do not pay anyone who claims they can bypass UIDAI’s verification requirements.

Can You Register a Mobile Number in Aadhaar for the First Time?

Yes, you can register a mobile number for the first time, but UIDAI’s current Aadhaar app FAQ says that first-time registration cannot be completed through the app. You must visit an Aadhaar Seva Kendra or an authorised enrolment and update centre.

At the centre, tell the operator that no mobile number is currently registered and provide the new number you want to use. Follow the prescribed verification process, pay the applicable charge, and keep the acknowledgement.

If this is your first registration, do not try to use the app’s change-number process as a substitute for the required centre visit.

Common Mistakes to Avoid

Before completing an Aadhaar mobile number update, avoid these common mistakes:

Using an unofficial app: Install the official Aadhaar app only from a trusted source.
Entering the wrong number: Double-check all digits before confirming.
Ignoring old-number access requirements: The app’s verification process depends on your circumstances.
Assuming the update is free: Check the current fee displayed by UIDAI.
Losing the acknowledgement: Save your reference number until the update is complete.
Expecting immediate completion: Processing can take time, so track the request.
Sharing OTPs with agents: Never disclose OTPs or other authentication credentials to unknown people.
Submitting duplicate requests unnecessarily: Check the existing request’s status before applying again.

A careful Aadhaar mobile number update helps you avoid delays and ensures you use the correct route for your situation.

Conclusion

Updating your registered mobile number is important if your old number is no longer active or you want to use a different number for Aadhaar-related services. UIDAI now documents an app-based update process for eligible users, while people who cannot access their old number or need to register a number for the first time must visit an authorised Aadhaar centre.

For an Aadhaar mobile number update, first check whether the official app can handle your situation. If not, locate a centre through UIDAI’s official channels, complete the required verification, pay the prescribed fee, and save your acknowledgement.

Use only official UIDAI services, follow the latest instructions, and track your request until the status confirms that the update has been completed.
