how to physically sign pan card

If your physical PAN card was issued without a signature, which often happens with e-KYC applications, it is considered invalid until you physically sign it. To validate the card, you should manually sign with a permanent pen on the white strip/space provided on the back of the card. For a card with a printed signature, you must apply for a correction or change in existing PAN data through official portals like Protean or UTIITSL, where you can upload a scanned copy of your signature during the application process.
