Check the credit information to know the credit card limit. However, this is the authority of the bank, which can check the number of credit card accounts of customers and the credit card limit and overdraft limit of each bank through the credit information network. Individuals do not have the right to "query other people's credit information".

Of course, there are ways, but it is illegal to inquire about other people's credit information casually, and in any case, the time of inquiry and the identity of the inquirer will be recorded in the credit information record. Once the customer finds out that his credit information has been secretly inquired, the customer can sue "PBOC". Once PBOC is sued, it will begin to investigate who secretly inquired about the customer's credit information. Then what after investigation, you find that it is you, you have to go to the public security bureau to cooperate with the investigation.
