Credit cards have a time limit. Generally speaking, credit cards are valid for 3 years. As long as you have used your credit card (including deposit) within 6 months before its expiration, the bank will automatically renew your insurance. If you don't want to continue using the card, you can call the bank's customer service hotline to apply for not renewing the card when it expires, and then the bank will send you a notice. You will fill it out and send it back to the credit card center, so you won't receive a new card. If your card has not been used once before the expiration date, and the expiration date has expired when you want to continue using the card, you can call the customer service center to apply for renewal within 6 months after the expiration date. If it is more than 6 months, you can only resubmit the application materials.
