Linking Your Mobile to Aadhaar: The One Job You Can't Do Online

A mobile number cannot be linked or changed in Aadhaar online — you must visit a centre in person with your biometrics.

The online IVRS number 14546 only re-verifies a number already linked; it cannot add a new one.

A demographic update at a centre costs ₹75 since 1 October 2025; some guides still quote the older ₹50, so confirm on the spot.

You leave with a 14-digit URN slip; the update usually reflects within about 30 days.

Without a linked number you cannot download e-Aadhaar, use mAadhaar, get DBT alerts or pass most OTP checks.
