How to Update Mobile Number in Aadhaar – Step-by-Step Guide (2026)

Your registered mobile number is the key to accessing almost every Aadhaar service online. From downloading e-Aadhaar to updating address or verifying KYC, OTP authentication is mandatory.

If your mobile number has changed or is no longer active, this guide explains how to update your mobile number in Aadhaar quickly and correctly.

Why Is Mobile Number Important in Aadhaar?

Your Aadhaar-linked mobile number is required for:

✔ OTP verification for online services
✔ Downloading e-Aadhaar
✔ Address update requests
✔ Aadhaar authentication for bank KYC
✔ Checking update status

Without an active registered mobile number, online Aadhaar services cannot be accessed.

Can You Update Aadhaar Mobile Number Online?

No, mobile number updates cannot be done online for security reasons. You must visit an Aadhaar Seva Kendra or authorized enrolment centre.

Step-by-Step Process to Update Mobile Number in Aadhaar

Step 1: Locate Nearest Aadhaar Centre

Visit the official UIDAI website and search for the nearest Aadhaar Seva Kendra.

Step 2: Visit the Centre in Person

Carry your Aadhaar card or Aadhaar number.

Step 3: Fill the Aadhaar Update Form

Select the option for mobile number update.

Step 4: Biometric Authentication

You will need to verify your identity using fingerprints or iris scan.

Step 5: Pay the Update Fee

The standard fee for demographic update (including mobile number) is usually ₹50.

Step 6: Collect Acknowledgement Slip

You will receive a slip containing your Update Request Number (URN) to track status.

Documents Required for Mobile Number Update

Generally, no additional documents are required if only updating the mobile number.
Biometric verification at the centre is sufficient.

How Long Does It Take?

Mobile number updates typically reflect within:

• 2 to 7 working days
• In some cases, up to a few weeks

You will receive an SMS confirmation once the update is successful.

How to Check Mobile Update Status

1. Visit the UIDAI website.
2. Enter your Update Request Number (URN).
3. Verify captcha.
4. Check status instantly.

Common Mistakes to Avoid

✔ Carrying incorrect Aadhaar number
✔ Not collecting acknowledgement slip
✔ Entering wrong new mobile number
✔ Delaying update after losing old SIM

Ensure your new mobile number is active and accessible for OTP verification.

What If You Lost Access to Old Mobile Number?

Even if your old number is not active, you can still update your mobile number by visiting an Aadhaar centre and completing biometric verification. Access to the old number is not mandatory for offline update.

Final Thoughts

Updating your mobile number in Aadhaar is essential for uninterrupted access to online services. Since Aadhaar authentication relies heavily on OTP verification, keeping your registered mobile number active ensures smooth digital access to banking, telecom, and government services.

If your number has changed, update it immediately to avoid service disruptions.
