How to Update Mobile Number in Aadhaar – 2025 Guide

Introduction – Why It’s Important to Keep Your Aadhaar Mobile Number Updated in 2025

Aadhaar has become the backbone of digital identity in India, connecting you to essential services like banking, PAN, UPI, ration, pension, income tax, and SIM verification. But here’s the catch — all these services rely on the mobile number linked to your Aadhaar for OTP-based authentication.

If your mobile number is outdated, lost, or not linked at all, you’ll be locked out of:

Downloading your Aadhaar card
Updating Aadhaar details online
Filing ITR via Aadhaar OTP
Applying for government schemes like PM Kisan, Ayushman Bharat
Verifying bank accounts or PAN cards
Doing biometric authentication at banks or ration shops

Aadhaar is critical for services like banking, PAN, UPI, and taxation. To avoid penalties or failed verifications, make sure your PAN is also linked.

In 2025, with UIDAI’s increased digital integration, having an updated mobile number is no longer optional — it’s mandatory for almost all Aadhaar-related services.

Whether your number has changed, was never added, or needs a correction, this step-by-step guide will show you how to update your Aadhaar-linked mobile number both offline and online (if eligible).

Without a valid mobile number, even basic functions like downloading your Aadhaar PDF become impossible.
