If your credit card is frozen due to overdue, you still have hope to reopen it. First of all, you need to know your personal credit status and whether it is included in the credit blacklist. You can check your credit status through the quick query tool of Beijian. Just check in: Beijian. Click "Query" and enter information to query your own credit data and personal credit status, including important data and information such as Internet black index score, blacklist, online loan application record, application platform type, overdue, overdue amount, credit card and online loan credit estimated amount. If you find yourself blacklisted because of overdue, you need to pay off the arrears first, wait for a while, and then apply for the right to use the credit card again. In addition, if it is not blacklisted, you need to contact the credit card customer service department to understand the specific unfreezing process, and complete the relevant application in strict accordance with the process before reopening the credit card.
