1. You can log in to the web page "XX Bank Credit Card Center" with your ID - click My Credit Card on the homepage - click Return Payment service - click on the contract status query and then you can see the credit card account number;

2. Go to the bank counter with valid documents to inquire;

3. Call the credit card center to provide relevant information Make an inquiry.

After losing your credit card, 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 and apply for a new card as soon as possible.

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.
