To check your PAN card number online, the most reliable method is through the official Income Tax Department's e-filing portal.
- Log in to the Income Tax e-filing portal using your credentials.
- Go to 'Profile Settings' and select the 'My Account' option to view your PAN details.
- Alternatively, you can use the official PAN mobile application, choose 'Know your PAN details', and access the information after verifying with an OTP sent to your registered mobile number.
Your PAN number is also generally printed on your previous bank statements or filed Income Tax Returns (ITRs).
