If you have lost your PAN card and have forgotten your PAN number, you can apply for a reissue of your PAN card. The procedure for reissuing a PAN card is similar to the procedure for applying for a new PAN card.

Here are the steps you can follow to reissue a PAN card:

1. Visit the official website of the Income Tax Department of India
2. Click on the “Services” tab, and then select “Apply for PAN” under the “PAN” section.
3. Select “Reprint of PAN card” as the category of application.
4. Fill in the online application form with the necessary details such as your personal information, contact information, and proof of identity and address.
5. Upload the required documents such as your passport-sized photograph and proof of identity and address.
6. Pay the necessary fee for the application.
7. Submit the application and note down the acknowledgement number generated.
8. Track the status of your application on the website using the acknowledgement number.
9. Once your application is approved, you will receive the new PAN card at the address mentioned in the application form.

It’s worth noting that, you can also apply for PAN card re-issuance by visiting the nearest UTIITSL or NSDL centre.

It’s also worth noting that, if you have lost your PAN card, it is advisable to immediately inform the bank where you hold an account, and also inform the IT department to avoid any misuse.
