Aadhaar has become the backbone of digital identity for every Indian. Whether you access banking services, apply for a loan, use UPI apps, or complete any KYC, your registered mobile number is the most important link to your Aadhaar.

Until recently, changing this mobile number required a mandatory visit to an Aadhaar Seva Kendra. But in 2025, UIDAI introduced one of its most awaited upgrades — the ability to update your Aadhaar mobile number online through the Aadhaar App, right from your home.

This update is a major relief for crores of Aadhaar holders, making the process faster, safer, and more accessible.

What’s New in Aadhaar: Mobile Number Update Now Available Online

UIDAI has rolled out a feature inside the Aadhaar App (formerly mAadhaar) that allows users to change their registered mobile number without visiting any Aadhaar centre.

This new feature has been launched as part of UIDAI’s broader digital modernisation, which also includes future online updates for name, address, DoB, and email.

Why This Update Is Important

No need to travel to an Aadhaar centre
No long queues or waiting
OTP-based verification on both old & new numbers
Added security with Face Authentication
Completely paperless
Small service fee of ₹75
Faster turnaround time

This update is especially helpful for users who lose their mobile number, face SIM issues, or need to link a different number urgently for banking and KYC purposes.

How to Change Your Aadhaar Mobile Number Online (Step-by-Step Guide)

Below is a user-friendly explanation of the new Aadhaar App process:

Step 1: Download & Login to Aadhaar App

You can download the latest Aadhaar App from the Google Play Store or Apple App Store.

What you’ll need:

Aadhaar number
Access to the currently linked mobile number for OTP

Once logged in, you will set a 6-digit App PIN for secure access.

Step 2: Go to “My Aadhaar Update” Section

Inside the app, look for the option:

My Aadhaar → Update Aadhaar → Mobile Number Update

This feature is newly added as part of the 2025 rollout.

Step 3: Enter & Verify Your Current Mobile Number

The app sends an OTP to the mobile number currently registered with UIDAI.
Enter the OTP to verify ownership.

This step ensures that only the legitimate Aadhaar holder can initiate changes.

Step 4: Enter Your New Mobile Number

Type the new number you want to link with your Aadhaar.

You will receive an OTP on the new mobile number as well.

This double verification makes the process highly secure.

Step 5: Complete Face Authentication

UIDAI has strengthened online Aadhaar updates through AI-powered face authentication, requiring:

Front camera scan
Blink / movement validation

This confirms your identity without the need for biometric data at a centre.

Step 6: Pay the ₹75 Service Fee

You can pay via:

UPI
Debit/Credit Card
Net Banking

The payment is processed instantly and the request is submitted to UIDAI.

Step 7: Track Status Inside the App

After successful submission, the Aadhaar App provides:

Update Request Number (URN)
Status tracking option

Updates usually reflect within a short period, depending on UIDAI’s processing load.

What’s Coming Next in the Aadhaar App?

UIDAI is reportedly preparing to enable more online updates:

Name correction
Address update
Email ID update
Date of Birth correction
Full e-Aadhaar digital ID features

These upgrades will eventually reduce the dependency on physical Aadhaar centres across India.

Is the Online Mobile Number Update Available for Everyone?

UIDAI is rolling out the feature in phases.
While many users already see the option in their app, some may get it gradually as backend systems update across regions.

If you don’t see the feature yet, update the Aadhaar App and check again after a few days.

Important Things to Remember

You do not need any documents
Do not share OTP with anyone
The fee is fixed at ₹75
Keep your Aadhaar App updated
Both old and new mobile numbers must be active during the process

Final Thoughts

The new Aadhaar App mobile number update feature is a major step forward in India’s digital identity system. It simplifies the process, reduces physical visits, and makes Aadhaar updates accessible to everyone — from cities to rural areas.

As banking, UPI, fintech, and government services increasingly depend on Aadhaar, having an up-to-date mobile number is critical. This online update capability makes life easier for millions of Indians.
