The service life of a credit card refers to the time from the issuance of the credit card to the cessation of its use. The validity period of a credit card can be viewed under the card number on the front of the credit card.

The valid format of the credit card is MM/YY, that is, the four digits below the front of the credit card. The first two digits represent the month, and the last two digits represent the year, for example, 04/2 1, which means the validity period is until April 30th, 20021year. When looking at the date, you need to pay attention to the order of the year and month.

Cardholders can also inquire about the service life of credit cards by calling the bank's customer service phone, or they can go to the bank's business outlets to inquire.
