Linking your Aadhaar card with your mobile number helps you access several Aadhaar-based services more conveniently. A registered mobile number is also important for receiving OTPs during Aadhaar authentication, downloading Aadhaar-related documents, and using online services provided by the Unique Identification Authority of India (UIDAI).
If your mobile number is not registered with Aadhaar, you generally need to visit an Aadhaar Seva Kendra or an authorised Aadhaar enrolment/update centre. The process is simple, but carrying the required documents and following the correct steps can save time.

Why Link Aadhaar with Mobile Number?
Aadhaar-linked mobile numbers provide an additional layer of convenience and security. Many Aadhaar services require OTP verification, which is sent to the mobile number registered with your Aadhaar.
A registered mobile number can help you:
- Receive Aadhaar OTPs
- Download an electronic Aadhaar copy
- Use online Aadhaar services
- Complete Aadhaar authentication
- Check certain Aadhaar service requests
- Receive important Aadhaar-related notifications
Keeping your registered mobile number active also makes it easier to manage Aadhaar services securely.
How to Link Aadhaar with Mobile Number
If you have never registered a mobile number with your Aadhaar, you generally need to complete the update through an Aadhaar centre.
Find an Aadhaar Enrolment Centre
Visit an authorised Aadhaar Seva Kendra or Aadhaar enrolment/update centre. You can use the UIDAI website to locate a suitable centre near you.
Request a Mobile Number Update
Tell the operator that you want to add or update your mobile number in your Aadhaar record. You may need to complete the Aadhaar update form with your details and the mobile number you want to register.
Provide Your Aadhaar Details
Give your Aadhaar number and the required information to the authorised operator. Make sure the details entered into the form are correct.
Complete Biometric Verification
The operator may verify your identity using your biometrics. This verification helps protect your Aadhaar information and prevents unauthorised changes.
Pay the Applicable Fee
A nominal fee may apply for updating Aadhaar details. The exact charges can change, so check the current fee before completing the request.
Collect the Acknowledgement
After submitting the request, you should receive an acknowledgement containing details such as the update request number. Keep this information safe so you can track the status of your request.
Can You Link Aadhaar with Mobile Number Online?
A common question is whether a new mobile number can be added to Aadhaar completely online. For security reasons, adding or changing the registered mobile number generally requires identity verification at an Aadhaar enrolment/update centre.
Online Aadhaar services can be used for several other tasks, but a new mobile number may require an in-person biometric verification process. Therefore, if your Aadhaar does not have a registered mobile number, visiting an authorised centre is usually the appropriate option.
How to Check Whether Your Mobile Number Is Linked with Aadhaar
You can use UIDAI’s official online services to check Aadhaar-related information and verify whether your mobile number is registered.
If you are unsure about your registered mobile number, use the official UIDAI portal rather than relying on unofficial websites or third-party applications.
What If Your Old Mobile Number Is No Longer Active?
If the mobile number previously registered with your Aadhaar is lost, inactive, or unavailable, you should update it with your new number through an authorised Aadhaar centre.
You should not share your Aadhaar OTP, biometric information, or other sensitive details with unknown people. Always use official UIDAI services or authorised centres for Aadhaar updates.
Documents Required for Mobile Number Update
For a mobile number update, the centre may primarily require your Aadhaar details and identity verification. Requirements can vary depending on the type of update and current UIDAI rules. Before visiting the centre, check the latest requirements and service charges through the official UIDAI website.
How Long Does Aadhaar Mobile Number Update Take?
The processing time can vary depending on the type of request and UIDAI processing. Your acknowledgement slip or update request number can help you track the progress of the request. Avoid making repeated requests unless necessary, as this can create confusion or additional costs.
