Aadhaar Card Mobile Number Link is an important service for keeping Aadhaar information updated and making Aadhaar-based online services easier to access. A registered mobile number can be used for OTP-based authentication and several Aadhaar-related services. UIDAI states that the registered mobile number is essential for accessing Aadhaar online services.
The process for updating or registering a mobile number has also changed with the introduction of the updated Aadhaar App. Eligible Aadhaar holders can now use the app for mobile number updates in certain situations, while people who have never registered a mobile number or who cannot access their old registered number may need to visit an Aadhaar Seva Kendra or authorised enrolment and update centre.
This article explains the Aadhaar Card Mobile Number Link process, online options, Aadhaar App procedure, centre-based update, required details, charges, status, OTP issues and other important points.
Why Link a Mobile Number With Aadhaar?
A mobile number linked with Aadhaar provides an important communication and authentication channel. Several Aadhaar services use OTP-based verification, so keeping the registered number active can make it easier to use online facilities.
A registered mobile number may be useful for:
- Receiving Aadhaar-related OTPs.
- Accessing eligible online Aadhaar services.
- Downloading or accessing certain Aadhaar services that require mobile authentication.
- Tracking update-related requests.
- Completing identity verification where Aadhaar OTP is supported.
- Receiving notifications related to Aadhaar services.
- Using the Aadhaar App and its available services.
UIDAI specifically notes that the registered mobile number is essential for Aadhaar online services.
Can Mobile Number Be Linked With Aadhaar Online?
The answer depends on what is meant by “online.”
The traditional MyAadhaar online update facility does not permit mobile number updates in the same way as an online address update. UIDAI’s enrolment and update FAQs state that mobile number update is not permitted through the older online update mode and can be done at an Aadhaar Enrolment Centre.
However, UIDAI’s current Aadhaar App provides a mobile number update facility. The process depends on whether the applicant has access to the existing registered number and how the Aadhaar App account is registered.
Therefore, Aadhaar holders should distinguish between the MyAadhaar portal and the current Aadhaar App when looking for Aadhaar Card Mobile Number Link options.
Aadhaar Card Mobile Number Link Through Aadhaar App
The Aadhaar App now provides mobile number update functionality. UIDAI has specified different procedures according to the applicant’s existing mobile-number situation.
When the Aadhaar App Uses the Same Registered Mobile Number
If the Aadhaar holder is registered on the Aadhaar App using the same mobile number that is already registered with Aadhaar, the new mobile number can be processed through the app.
The user needs to:
- Open the Aadhaar App.
- Access the mobile number update service.
- Enter the new mobile number.
- Verify the new number through OTP.
- Complete Face Authentication.
- Pay the applicable prescribed charge.
- Submit the request.
- Save the acknowledgement or request details for future reference.
UIDAI confirms that OTP verification of the new number and Face Authentication are required in this scenario.
When the Aadhaar App Uses a Different Mobile Number
A different situation applies when the number used for Aadhaar App registration is not the same as the mobile number currently registered with Aadhaar.
In this case, UIDAI requires verification of both the old registered mobile number and the new mobile number through OTP, followed by Face Authentication and payment of the applicable charges.
This additional verification helps establish control over the existing registered number before the new number is submitted for updating.
How to Link Mobile Number With Aadhaar Through the Aadhaar App
The general process can be understood through the following steps:
- Install and open the official Aadhaar App.
- Register or log in using the Aadhaar details and authentication method supported by the app.
- Open the available services section.
- Select the mobile number update option.
- Enter the mobile number that you want to register with Aadhaar.
- Complete the required OTP verification.
- Follow the Face Authentication instructions shown by the app.
- Pay the applicable update charge.
- Submit the request.
- Keep the request or acknowledgement details safely.
UIDAI says the Aadhaar App supports mobile number updates along with other services such as address update, biometric lock or unlock, authentication history and e-Aadhaar access.
The exact screens or wording displayed in the app may change as UIDAI updates the application, so applicants should follow the options currently shown inside the official app.
Mobile Number Link Through Aadhaar Enrolment Centre
Aadhaar holders can also update or register their mobile number by visiting an Aadhaar Enrolment or Update Centre.
This option is particularly important for people who cannot use the Aadhaar App process.
The centre-based process generally involves:
- Visit an Aadhaar Enrolment or Update Centre.
- Provide your Aadhaar number and request a mobile number update.
- Tell the operator the new mobile number.
- Complete the required identity and biometric authentication.
- Review the details entered by the operator.
- Pay the applicable fee.
- Collect the acknowledgement slip.
- Use the acknowledgement information to track the request where applicable.
UIDAI confirms that mobile number updates can be completed at Aadhaar Enrolment Centres. It also states that the same centre where the original Aadhaar enrolment was completed is not required, meaning an Aadhaar holder can use another authorised centre for an update.
Can I Link Aadhaar With a Mobile Number Without the Old Number?
Yes, an old mobile number is not always required for the centre-based update process.
If you no longer have access to the mobile number previously registered with Aadhaar, UIDAI says you should visit an Aadhaar Seva Kendra or authorised Aadhaar enrolment and update centre. The current Aadhaar App guidance also directs users without access to the old registered number to use an authorised centre.
At the centre, the applicant can request an update to the new mobile number and complete the required verification process.
This means losing an old SIM card does not permanently prevent a person from changing the mobile number associated with Aadhaar.
Aadhaar Mobile Number Link Without OTP
If the old registered mobile number is unavailable, the applicant may not be able to complete the OTP-based app procedure that requires verification of the old number.
In such a situation, visiting an Aadhaar Seva Kendra or authorised Aadhaar enrolment and update centre is the appropriate route under UIDAI’s current guidance.
The centre-based process uses the required identity and biometric verification instead of relying solely on access to the old mobile number.
Applicants should avoid unofficial websites or people claiming that they can change the Aadhaar mobile number remotely without authentication.
Is Any Document Required for Aadhaar Mobile Number Update?
For a standard mobile number update, UIDAI’s FAQ states that no document or old mobile number is required when the update is submitted through an Aadhaar Enrolment Centre or through the supported postman service.
However, applicants should carry their Aadhaar details and follow the identity verification instructions given at the centre.
The operator will enter the requested mobile number into the Aadhaar update system and complete the applicable authentication process.
It is always sensible to check the current requirements displayed at the authorised centre before submitting the request because service procedures can be revised by UIDAI.
Aadhaar Mobile Number Update Charges
Mobile number is classified by UIDAI as demographic information. UIDAI’s current Aadhaar service charge information states that a demographic update, including mobile number, costs ₹75 when performed separately at an Aadhaar centre. If demographic information is updated at the same time as a biometric update, different fee rules may apply.
The applicable charge should be checked before submitting the request, and the amount should appear on the acknowledgement slip issued by the centre.
Aadhaar holders should be cautious if someone asks for an unusually high amount for a normal mobile number update.
What Information Is Updated in Aadhaar?
A mobile number is part of Aadhaar’s demographic information.
UIDAI identifies the following among the demographic details that can be updated:
- Name
- Address
- Date of Birth or Age
- Gender
- Mobile Number
- Email Address
- Other applicable demographic information
Biometric information is handled separately and includes fingerprints, iris information and facial photograph.
Changing a mobile number does not create a new Aadhaar number. UIDAI confirms that the Aadhaar number remains the same after an update.
How to Check Whether Mobile Number Is Registered With Aadhaar
UIDAI provides a facility to verify the mobile number declared with Aadhaar.
Aadhaar holders can use the official Aadhaar services and follow the mobile-number verification option. The purpose of this facility is to help determine whether the mobile number associated with the Aadhaar record is the number currently being used.
If OTP-based services are not working, checking the registered mobile number can help identify whether the issue is related to an outdated number.
How Long Does Aadhaar Mobile Number Update Take?
Aadhaar updates are subject to processing and validation. UIDAI states that normally 90% of update requests are completed within 30 days.
This should not be treated as a guaranteed fixed processing period for every request.
The request may take additional time if verification or processing requirements apply. Applicants should therefore keep their acknowledgement details until the update has been successfully reflected.
How to Check Aadhaar Mobile Number Update Status
After submitting the update request, keep the acknowledgement or request details supplied during the process.
Depending on the service used, the available tracking facility can be used to check the progress of the request.
The general process is:
- Open the official Aadhaar service.
- Select the update status option.
- Enter the required request or enrolment details.
- Complete any authentication requested.
- View the current status.
- Wait for completion if the request is still under processing.
UIDAI’s MyAadhaar services include facilities for checking Aadhaar update status.
What Happens After the Mobile Number Is Updated?
Once the mobile number update has been successfully processed, the new number becomes the registered mobile number associated with the Aadhaar record.
No new Aadhaar number is issued because of a mobile number change. UIDAI also states that an Aadhaar letter is not delivered after updating only the mobile number or email address.
The updated number can subsequently be used for eligible Aadhaar services requiring mobile authentication.
Applicants should make sure that the new SIM is active and capable of receiving SMS messages.
Can One Mobile Number Be Used With Multiple Aadhaar Numbers?
Yes, UIDAI’s current FAQ states that a maximum of nine Aadhaar numbers can be linked with a single valid mobile number.
This can be useful in households where family members use a common mobile number for Aadhaar-related purposes.
However, each person’s Aadhaar record remains separate. Linking the same mobile number with multiple Aadhaar numbers does not combine the Aadhaar records or change their individual identity information.
Aadhaar Mobile Number Link for Children
A child’s Aadhaar record can also contain demographic information, including a mobile number where applicable.
Parents or guardians should ensure that the information supplied during enrolment or update is accurate and belongs to the appropriate person.
For any child-related Aadhaar update, the applicable enrolment and update procedure should be followed at an authorised centre or through the Aadhaar App where the service is available.
Common Reasons for Mobile Number Update Problems
A mobile number update may not proceed smoothly for several practical reasons.
OTP Is Not Received
Check whether the relevant mobile network is working and whether the correct number was entered. If the required old number is unavailable, use the centre-based process instead of repeatedly trying an OTP-based method.
Old Number Is No Longer Active
If the old registered mobile number cannot receive OTPs, the current Aadhaar App rules direct the user to an Aadhaar Seva Kendra or authorised enrolment and update centre.
Face Authentication Fails
When using the Aadhaar App, make sure the face is clearly visible and follow the instructions shown during authentication. Poor lighting or incorrect positioning can interfere with the process.
Update Is Still Pending
An update request may remain under processing because UIDAI validates submitted information before completing the update. Submission of a request does not automatically guarantee acceptance.
Mobile Number Was Entered Incorrectly
Always review the new number before final submission. A mistake in the number can prevent OTPs and Aadhaar notifications from reaching the intended mobile device.
Aadhaar Mobile Number Update: App vs Centre
| Feature | Aadhaar App | Aadhaar Enrolment Centre |
|---|---|---|
| Mobile number update | Available in supported scenarios | Available |
| Face Authentication | Required in app process | Centre-based authentication applies |
| Old mobile number unavailable | Centre is required | Available |
| First-time mobile registration | Centre is required | Available |
| OTP verification | Required according to scenario | Not dependent solely on old mobile OTP |
| Physical visit | Not required for eligible app scenarios | Required |
| Applicable fee | Prescribed charge | Prescribed centre charge |
The important point is that not every applicant will qualify for the same digital route. UIDAI’s current guidance specifically separates app-based cases according to access to the old registered number and previous app registration.
