What is Aadhaar OTP Verification?
Aadhaar OTP verification is a security check that confirms you're genuinely the person the Aadhaar number belongs to.
A one-time password is sent to the mobile number linked with your Aadhaar. Entering it correctly is what proves your identity to the system on the other end.

Common OTP Problems
Check your network coverage, then wait a few minutes before requesting another OTP rather than retrying immediately.
The OTP only goes to whichever mobile number is currently linked with your Aadhaar — update it with UIDAI first if it's changed.
Too many incorrect attempts can lock the request — you'll need to generate a fresh OTP and start again.
Several Income Tax services won't proceed until PAN and Aadhaar are linked — worth checking this before you start.
Security Tips
- ✓ Never share your OTP with anyone — not even someone claiming to be from the bank or Income Tax Department.
- ✓ Only use the official Income Tax and UIDAI websites for anything Aadhaar-related.
- ✓ Don't click on refund links sent through SMS or WhatsApp — the department doesn't send refunds that way.
- ✓ Double-check the website URL before typing in any Aadhaar details, especially on a link you didn't search for yourself.
