You can apply for a duplicate PAN card in the following situations:
Theft and loss: People often carry their PAN cards within their wallets or pockets. It is possible to lose your card when you lose your wallet/purse. This is one of the most common reasons for multiple applications to the department in India.
Misplaced: It has happened on a number of occasions when people leave the card somewhere and are later unsure as to where it actually is.
If the PAN card is damaged, it is necessary to reprint it.
Change in information: A PAN can be issued with information and a signature that have changed over time. In this case, we are left with only one solution, i.e. to change it and reprint the card with the information changed.
