If your credit card is frozen, it will show that you cannot spend when you swipe the card.

There are three ways to check whether a credit card has been frozen:

1. Telephone inquiry: Call the hotline on the back of the card and directly check and fill in the information.

2. Inquiry on the bank's official website: Enter the credit card interface and select credit card management (the names of the options may be different among major banks), and you can directly check the credit card status.

3. Counter inquiry: Bring your identity document and credit card directly to the bank branch where the card is located and inquire directly.

The process of unfreezing a credit card after it is frozen:

1. If it is frozen manually, the cardholder should call the customer service hotline and apply for unfreezing after repaying the amount in full.

2. If the account is in arrears for more than 30 days, the system will automatically freeze the account. After the cardholder pays off the minimum repayment amount, the card will automatically unfreeze.

3. Once frozen, fraud and judicial accounts will not be unfrozen, and applications for unfreezing accounts that have been in arrears for more than 4 weeks will generally not be approved.
