How to Update Mobile Number in Aadhaar Online Without Going to Centre

A changed or discontinued SIM can quickly interrupt Aadhaar services that depend on OTP authentication. For anyone searching for how to update mobile number in aadhaar online, the position changed in 2026: UIDAI’s new Aadhaar App now supports a remote mobile-number update for eligible users. The route depends on how the app is registered and whether the old Aadhaar-linked number is still accessible. If that number is unavailable, the update moves to an Aadhaar Seva Kendra, authorised centre or the postman service instead. This article explains how to update mobile number in aadhaar, the three UIDAI scenarios, the app and centre processes, the current fee, expected processing time and request tracking.

Why Your Aadhaar-Linked Mobile Number Matters

A registered mobile number supports OTP-based Aadhaar services, including:

• OTP authentication for supported Aadhaar services and profile access;
• downloading or accessing Aadhaar-related digital services where a registered-number OTP is used;
• identity verification or e-KYC journeys that use Aadhaar OTP authentication; and
• receiving update-related notifications from UIDAI.

Not every Aadhaar service relies on OTP; some use Face Authentication or biometrics. Problems mainly arise when a service sends an OTP to a number that is no longer accessible.

Which Update Method Applies to You? Three Scenarios

UIDAI therefore treats mobile updates differently according to the number used to register the app. The old Aadhaar-linked number is required for OTP only in the second app scenario.

Scenario 1 and 2: Update via the Aadhaar App

The aadhaar app mobile update applies to UIDAI’s first two scenarios. App registration uses SIM binding and Face Authentication; the update then uses the applicable OTP verification and Face Authentication.

Scenario 3: No Registered Number or Old Number Inaccessible

If the old number is inaccessible, or no number was registered earlier, UIDAI directs the Aadhaar holder to a Seva Kendra, authorised update centre or postman route. UIDAI states that neither the old mobile number nor a document is required merely for this mobile-number update.

Step-by-Step: Update Aadhaar Mobile Number Using the Aadhaar App

For eligible users, the app provides a remote route for how to update mobile number in aadhaar online.

1. Register on the official Aadhaar App. Enter the Aadhaar number, select the SIM, complete Face Authentication and set the six-digit PIN.
2. Open Mobile Number Update. Select the service after logging in.
3. Enter the new mobile number. The new number is verified by OTP.
4. Complete the required OTP checks. For a same-number app profile, verify the new number. For a different-number profile, verify both old and new numbers by OTP.
5. Complete Face Authentication. UIDAI Face Authentication verifies identity before submission.
6. Pay the prescribed update charge. UIDAI’s current demographic update schedule lists ₹75 for an update that includes a mobile number.
7. Submit and retain the request reference. Retain the generated reference and use the app's tracking facility.

Note: The myAadhaar web portal and Aadhaar App are separate channels; the 2026 app supports eligible mobile updates remotely.

Step-by-Step: Update Aadhaar Mobile Number at a Centre or Through Postman

The assisted route applies when the old number is inaccessible or a number is being registered for the first time.

8. Locate an authorised Aadhaar centre. Use UIDAI's centre locator or Bhuvan Aadhaar portal.
9. Request a mobile-number update. Provide the Aadhaar number and the new mobile number to be registered.
10. Complete the centre verification process. The operator completes the required authentication and submits the request.
11. Pay the applicable fee. The current UIDAI schedule lists ₹75 for a separate demographic update such as a mobile-number change.
12. Collect the acknowledgement. Retain the acknowledgement for tracking.

UIDAI also confirms a postman route. IPPB lists Aadhaar mobile-number update as a doorstep service through Postmen and Gramin Dak Sevaks, subject to availability.

Note: The postman option depends on local availability; current India Post or IPPB information applies.

Fee, Processing Time and How to Track the Update Request

UIDAI states that normally 90% of update requests are completed within 30 days, while some may take 30-90 days. Requests remain subject to UIDAI validation, and the Aadhaar number does not change.

Note: UIDAI may revise fees or app features; official instructions apply at submission.

Conclusion

The 2026 Aadhaar process offers a remote option, but not in every situation. For readers checking how to update mobile number in aadhaar online, UIDAI now permits an app-based update in its first two scenarios using OTP verification, Face Authentication and the prescribed charge. Understanding how to update mobile number in aadhaar also means recognising the limit of that route: where the old registered number is inaccessible or no number was registered earlier, an Aadhaar centre or postman service remains relevant. The route depends on app registration and whether the existing Aadhaar-linked number is accessible, rather than one method applying to every holder.
