Generally speaking, the data between different banks are independent of each other. Even if one bank controls or restricts your bank card, other banks will not know the specific situation immediately. Each bank has its own internal system and data management program, and will not share personal privacy and account information. This means that other banks will not take the initiative to understand your control over the Bank of Communications credit card.

However, in some cases, according to the requirements of laws and regulations or when financial security issues such as anti-fraud and money laundering are involved, banks may share relevant information through legal channels and put your information into a shared blacklist or similar control system. In this case, other banks may inquire about your control information in the process of risk assessment and credit approval.

In short, under normal circumstances, other banks will not directly know the control situation you face on the Bank of Communications credit card, but under certain circumstances, there may be an information sharing mechanism.
