Canceling a card and closing an account are different, but if you only have one credit card in this bank, canceling the card means closing the account, and there is no need to process it twice. If you are worried, you can ask the bank's customer service when applying for card cancellation. If it is not canceled together, it is still recommended that you apply for account cancellation after canceling the bank credit card. Because if you just cancel the card, then if you apply for a credit card from the bank next time, you will not be able to enjoy the treatment of a new customer; and canceling the account will clear your account information in the bank, so if you apply for a credit card again after a period of time, Banks can apply for cards according to preferential treatment for new customers.
