The Unique Identification Authority of India (UIDAI) has recently introduced a convenient way for Aadhaar holders to update their mobile numbers from the comfort of their homes. The new feature in the official Aadhaar app eliminates the need to visit an enrolment centre, which is especially helpful for senior citizens, residents living far from offices, or those who want to avoid long queues. Here’s a detailed guide on how to update your Aadhaar-linked mobile number using the official UIDAI app.

Step 1: Download or Update the Official Aadhaar App

First, ensure that you have the latest version of the UIDAI Aadhaar app installed on your smartphone. You can find it on the Google Play Store for Android or the Apple App Store for iOS. Updating the app is necessary to access the new mobile number update feature.

Step 2: Open the App and Select ‘Mobile Number Update’

Once the app is updated, open it and navigate to the “Mobile Number Update” option displayed on the home screen. This menu allows you to change the mobile number linked to your Aadhaar.

Step 3: Enter Your New Mobile Number

Type in the mobile number you wish to link with your Aadhaar. The app will send a One-Time Password (OTP) to this number for verification.

---

Step 4: Authenticate Using Face Verification

After receiving the OTP, the app will prompt you to complete face authentication. This ensures that only the Aadhaar holder can authorize the mobile number update.

Step 5: Submit the Request

Once OTP verification and face authentication are completed, the app processes your request. Your updated mobile number is then recorded in the UIDAI database, and you will receive confirmation on both your old and new numbers.

Other Features in the Aadhaar App

While the app shows options to update other details such as address, email, and name, most of these updates are not yet fully functional for self-service. Key changes like biometric updates, photo modifications, date of birth corrections, and iris scans still require an in-person visit to an Aadhaar enrolment centre, where staff and equipment can verify and update these details.

New Rules for Entities Using Aadhaar

UIDAI has also mandated that entities collecting Aadhaar details, such as hotels, event venues, or businesses, must register with the authority before using Aadhaar for verification. Registered entities can verify identity through QR codes, the UIDAI app, or an API, which strengthens data security and aligns with the Digital Personal Data Protection Act. This step aims to reduce Aadhaar misuse, limit dependency on intermediaries, and ensure safer customer verification.
