Aadhaar Mobile Number Update – How to Link, Change or Verify Your Mobile Number Online
Aadhaar Card is an essential identity document for millions of Indian residents. It is commonly used for banking, government services, education, identity verification, and various digital applications. However, many Aadhaar-related online services require access to a registered mobile number for secure authentication.
If your mobile number is not linked with Aadhaar, has been changed, or is no longer active, you may face difficulties receiving OTPs and accessing online services. Fortunately, the Unique Identification Authority of India (UIDAI) provides facilities for Aadhaar Mobile Number Update, verification, and registration.
With the official Aadhaar app, eligible residents can now update their mobile numbers using OTP and face authentication. Certain situations, including first-time mobile registration or loss of access to the old registered number, still require visiting an authorised Aadhaar centre. This guide explains the complete process, documents, charges, status checking, and common problems.
What Is Aadhaar Mobile Number Linking?
Aadhaar Mobile Number Linking means registering a mobile phone number in your Aadhaar records maintained by UIDAI.
The registered number is used for OTP-based authentication when accessing supported Aadhaar services. It is different from simply using Aadhaar for SIM card verification.
Keeping your registered number active makes digital identity management more convenient and helps prevent unauthorised access.
Aadhaar holders may need to update their registered number when changing SIM cards, losing access to an old number, or correcting outdated contact information.

Why Is a Mobile Number Important for Aadhaar?

Aadhaar Updates: Certain online update services require identity verification before accepting requests.
Authentication History: Residents can review Aadhaar authentication records through supported UIDAI services.
Digital Verification: OTP-based Aadhaar authentication may be used by eligible service providers with appropriate consent.
Security: Maintaining an accessible mobile number helps you manage authentication and receive important verification messages.
Although a registered number is useful, Aadhaar can also support other forms of authentication depending on the service.
How to Update Aadhaar Mobile Number Online Using the Aadhaar App
UIDAI’s official Aadhaar app provides a mobile number update facility for eligible users.
The process uses secure identity authentication rather than allowing anyone to change a number simply by entering Aadhaar details.
Step-by-Step Online Update Process

Download the official Aadhaar app published by UIDAI from your smartphone’s authorised application store.
Check the publisher carefully before installation.
Step 2: Register on the App
Open the application, select your preferred language, enter your Aadhaar number, and complete the registration instructions.
App registration includes face authentication and setting a secure PIN.
Step 3: Select Mobile Number Update
After successful registration, open the available services and select the mobile number update facility.
Step 4: Enter the New Mobile Number
Provide the mobile number you want to register with Aadhaar. Check every digit before proceeding.

Verify the new number using the OTP received.
Depending on how you registered on the app, verification of your existing Aadhaar-registered number may also be required.

Ensure proper lighting and keep your face visible.
Step 7: Pay the Applicable Charge
Complete the prescribed payment if requested. Always confirm the official fee displayed in the application.

In such cases, the normal app-based update process cannot be used when access to the old registered number is required.
UIDAI directs residents without access to their old registered number to an authorised Aadhaar centre.
At the centre, identity verification allows the registration of a new mobile number through the appropriate update procedure.
Never use unofficial services claiming to bypass Aadhaar authentication.
