Mobile number and Aadhaar

Update or Link Mobile Number With Aadhaar: Current UIDAI Options

UIDAI’s 2026 service model changed an important old assumption: mobile-number update is now documented in the Aadhaar App, while authorised Aadhaar update centres remain part of the update ecosystem.

Independent website: We cannot link or change your mobile number. Use UIDAI’s official app or authorised Aadhaar update services.

Mobile Number Update Is No Longer Centre-Only

Freshness correction: Older pages that say mobile number update can only be done at a centre are no longer complete. UIDAI now documents Mobile Number Update in the Aadhaar App.

How UIDAI Describes Mobile Update in the Aadhaar App

Same registered number

UIDAI says the new mobile number is verified with OTP, followed by Face Authentication and the prescribed payment flow.

Different app number

UIDAI says both the old registered mobile number and new mobile number are verified with OTP, followed by Face Authentication and the prescribed payment flow.

Face Authentication

The current Aadhaar App registration and update process uses Face Authentication, as documented in UIDAI’s official guidance.
