While trying for PAN-Aadhaar linking, I get a message that the authentication has failed. What should I do?

If you see an 'authentication failed' message while linking your PAN with Aadhaar, it usually means there is a mismatch in the details (like name, date of birth, or gender) between your PAN and Aadhaar records. To resolve this issue, you can:

1. Check Details: Verify that the name, date of birth, and gender on your PAN and Aadhaar are exactly the same. Even a small difference can cause authentication to fail.

2. Update Information: If there is a mismatch, update your information:

   • Update PAN details via the NSDL website, or
   • Update Aadhaar details offline through Aadhaar enrolment centers.

3. Try Again After Update: Once the information matches, try linking your PAN and Aadhaar again.

Note: You may need to wait for the updates to reflect, which can take a few days.
