1. Call the bank customer service. Under normal circumstances, when the customer service staff of the bank calls to inquire about the freezing of the bank card, they can find out the reason for the freezing of the bank card through the intranet and then tell the consultant.

2. Bank counter consultation. Take the frozen card to the bank counter to find out why it is frozen. Bank personnel will inquire through the bank's internal system and inform them of the freezing reasons.

3. Inquiries about the judiciary. When the judicial department freezes personal bank card property, it can only freeze personal property with the approval of relevant institutions.

4. Online inquiry. If the bank card is frozen, there will be a prompt when logging in online. Of course, the specific reasons need to be inquired by the internal system of the bank or the judiciary.

Generally speaking, bank cards are frozen for the following reasons:

1. Your bank card is a credit card. If it is frozen, your credit card may have abnormal transactions, such as malicious cash withdrawal, forged information, consecutive password errors, etc. And your bank card may be frozen by the bank.

2. A bank card that can be overdrawn. The bank will set your overdraft share according to your actual repayment ability. When your overdraft exceeds your share, the bank will freeze your bank card immediately.

Your bank card is a debit card. If it is frozen, one is the wrong account freezing, that is, the bank mistakenly added more money to your account during the transaction, then the bank may freeze the extra money for you. The first is the judicial freeze. According to the relevant provisions of the law, the judicial organ may apply to the bank to freeze your bank card for handling cases. At the same time, customs, tax authorities and other departments also have the right to freeze.

4. No matter what kind of bank card you enter the password for three times in a row, the banking system will automatically lock your bank card password, which is similar to freezing, but not freezing. It will be released automatically after 24 hours.

If you don't get a new card when your bank card expires, the bank will freeze your expired bank card after it expires.

6. If your bank card reports the loss several times in a row, it will be frozen by the bank on suspicion of malicious loss reporting.
