Credit cards need to be cancelled when they are not used. Credit card is a special card that provides credit proof for cardholders, who can use it to shop, consume or enjoy specific services. If the credit card is not used, it can be cancelled in time to prevent it from being used by criminals and bringing unnecessary economic losses to the cardholder. Some credit cards still have annual fees, even if they are not used, they may owe money because of the annual fees, and credit cards are still quietly overdrawn, thus leaving bad credit records for cardholders. Cancellation can also prevent being used by criminals and bring unnecessary economic losses to cardholders. Therefore, regardless of whether the credit card has expired or not, it is best to consult the credit card customer service center and cancel it in time when it is confirmed that it has not been used.
