Documents & Information You Need
| Document/Info | Details | Where to Find |
|---|---|---|
| PAN Card | 10-digit alphanumeric code | Physical card or e-PAN (email) |
| Aadhaar Number | 12-digit unique identity | Aadhaar card or UIDAI website |
| Name (as on PAN) | Exact spelling on PAN card | PAN card |
| Registered Mobile | For receiving OTP | Mobile used for Aadhaar registration |
| Email Address | For verification | Your active email |
Troubleshooting: Common Errors & Solutions
Cause: Name on PAN and Aadhaar don't match exactly (spelling, spaces, initials).
Solution:
- Check exact spelling on your PAN card (middle names, initials)
- Use exact same spelling when entering the name
- If names differ, update Aadhaar name first on UIDAI portal
Cause: Your Aadhaar is already linked to a different PAN.
Solution:
- You cannot link one Aadhaar to multiple PANs
- Check which PAN is linked (use status checker tool)
- Contact the Income Tax Department if this is an error
- If you have multiple PANs, link the correct one first
Cause: Mobile or email not registered with Aadhaar, or network issue.
Solution:
- Check if OTP was sent to correct mobile (update Aadhaar registered mobile)
- Wait 2-3 minutes and try again
- Try alternative verification method (SMS instead of email)
- Check if you've exceeded OTP request limit (max 3 per hour)
Cause: Link not processed yet or verification pending.
Solution:
- If linked online: Link is active immediately (no waiting)
- If linked offline: Wait 2-4 weeks for processing
- Check status using the tool on the right sidebar
- If still inactive after 30 days, contact NSDL or e-filing support
