to unfreeze a bank card, you need to go to the opening bank. When the cardholder's related bank card account is frozen, the cardholder needs to bring his ID card and related bank card to any branch of the bank where the account is opened to handle the related unfreezing business. However, there are many reasons why the bank card is frozen. When the cardholder applies to the bank, the bank will first inquire about the reasons why the bank card is frozen, and then go through the thawing procedures according to the reasons.

1. If your bank card is frozen, you can't make any transfer transactions. The parties need to apply to the bank for unfreezing in time. If it is frozen by the judiciary, it needs to apply to the people's court. Bank card freezing means that the user's bank card is temporarily controlled by the banking system for some reasons and cannot be traded. The bank card freezing authority is not the opening bank, as long as it is the bank where the bank card is located.

2. There are many reasons why the bank card is frozen, including bank behavior, judicial behavior, and of course your bad behavior. The details are as follows:

1. Your bank card is a credit card (debit card). If it is frozen, it may be that your credit card has had abnormal transactions, such as malicious cashing, forged information, continuous password errors, etc., and the bank card may be frozen.

2. For overdrawn bank cards, the bank will set an overdraft share for you according to your actual repayment ability. When you overdraw beyond the share, the bank will immediately freeze your bank card.

Third, your bank card is a debit card. If it is frozen, it will be frozen in wrong account, which means that the bank mistakenly gave more money to your account when trading, so the bank may freeze the part that was given to you. One is judicial freezing. According to the relevant provisions of the law, the judicial organ can apply to the bank for freezing your bank card because of the need of handling cases. At the same time, customs, tax authorities and other departments also have the right to freeze.

4. No matter what bank card you enter, if you make mistakes three times in a row, the banking system will automatically lock your bank card password, which is similar to freezing, but not freezing. 24 hours will be automatically released later.

5. If your bank card fails to apply for a new card upon expiration, the bank will freeze your expired bank card after expiration.

6. If your bank card has been reported lost for many times in a row, it will be frozen because the bank thinks it is suspected of malicious loss reporting.
