The method is as follows:

1. After your credit card is lost, immediately call the 24-hour customer service hotline of the card-issuing bank, provide your basic information, and ask the staff to report the loss of your credit card for you as soon as possible and Apply for a new card.

2. Bring your ID card to the credit card department of the bank to report the loss. It is best to go through it in person as the procedure will be simpler. If you need someone else to do it for you, you need to write a power of attorney and stamp it.
