Call the customer service number on the back of the credit card and ask the customer service to help you inquire! Also, you can go to the People's Bank to check your personal credit report, and all your credit card records can be found.

The date on the card is the validity period of the credit card. After the expiration of the validity period, the bank will decide whether to let customers continue to use credit cards according to their past use. If you have more detailed inquiries about the opening time of the credit card or don't know how to inquire about the opening time of the credit card, you can call the bank customer service phone on the back of the credit card for detailed inquiries or directly ask the customer service for help.
