How to Register/Update Mobile Number in Aadhaar Card Online?

Last Updated : Jan. 4, 2025, 3:58 p.m.

According to UIDAI's official website, to use the online Self Service Update Portal (SSUP) for updates, your mobile number must already be registered with your Aadhaar. If not, you can register or update your mobile number by visiting the nearest Permanent Enrollment Centre with the necessary supporting documents. This article explains how to do just that, along with detailing the required documents for the process. The government mandates linking the Aadhaar card —one of the most essential forms of identification—to various documents and financial instruments.

This linkage is crucial for receiving government subsidies directly in the beneficiaries' bank accounts under schemes such as DBT and Pahal. Registered mobile numbers receive confirmation messages, enabling beneficiaries to track their entitled benefits. Without a linked mobile number, these updates cannot be received, potentially causing you to miss out on important benefits.

How to Add Mobile Number in Aadhar Card?

Previously, the SSUP provided an online facility for registering mobile numbers with Aadhaar. However, this service has been discontinued, and applicants must now visit an Aadhaar Enrollment/Update Centre to register or update their mobile number in Aadhaar. The process of updating can take up to 90 days. To add mobile number in Aadhaar card, follow these steps:

1. Visit the UIDAI official website to find the nearest enrollment center.

2. Complete the Aadhaar Correction Form.

3. Mention your current mobile phone number that needs to be updated in Aadhaar.

4. Fill out the form and provide your biometric information for authentication.

5. The executive will hand you an acknowledgment slip containing an Update Request Number (URN), which can be used to monitor the status of your Aadhaar update request.

6. After updating your mobile number in Aadhaar, there is no need to obtain another Aadhaar card.

7. Once your mobile number is registered, you will begin receiving Aadhaar OTPs for various services.

8. You can also find out the status of your Aadhaar update by calling the UIDAI free number: 1947.

Reasons to Register Your Mobile Number in Aadhaar

There are several reasons to register your mobile number with Aadhaar:

• An OTP is sent to the registered mobile number to access the majority of Aadhaar-related services. This OTP must be provided to use the service, adding an additional layer of security to Aadhaar. If your phone number isn't linked to Aadhaar, you won't be able to use these services.

• You must register your mobile number with UIDAI to use any Aadhaar-related online services.

• To download your Aadhaar online, you must enter the OTP sent to your mobile number.

• You can only download the mAadhaar app and have Aadhaar on your phone if your mobile number is registered with Aadhaar.

Documents & Fee for Aadhar Mobile Number Registration

When you register or update your mobile number in Aadhaar, you need to pay a fee of Rs. 50 at the Aadhaar Enrollment/Update Center. This fee applies every time the mobile number is updated. However, the applicant is not required to submit any documents to update or register the mobile number in Aadhaar. Only the Aadhar Update Form with the current mobile number and the fee must be submitted.

Wrapping Up!

Adding your mobile number to your Aadhaar is crucial if you want to make the most of Aadhaar-related services. It's the key to receiving timely OTPs for authenticating transactions and services, ensuring everything runs smoothly. If you ever change your phone number, just swing by an Aadhaar Enrollment Centre to update it. Remember, a small fee of Rs. 50 will apply, but it's a straightforward process and you can track the update with the URN they give you.
