It is not possible to find your PAN card number online using only your mobile number, as your mobile number is not linked to your PAN card.

The PAN card number is issued by the Income Tax Department of India and can be found on the physical card or in official communications from the department.

If you have lost your PAN card and you have the number, you can visit the official website of the Income Tax Department of India to download a duplicate PAN card.

If you don’t have the number, you will have to apply for a new PAN card.
