If the loan bank card number is wrong, under normal circumstances, the financial institution requires the borrower to provide a valid bank card to bind the personal loan account, and the formal platform will verify whether the borrower's name, ID card, mobile phone number and bank card are unified. If it is inconsistent with the platform, the borrower will be reminded at the first time, so that the wrong bank card cannot be bound successfully. If the bank card is found to be wrong after the loan is successful, the borrower only needs to log in to the personal account center in time and correct the bank card information. If the bank card number filled in by the borrower at the time of loan is cancelled, abnormal or frozen, it is generally impossible to withdraw cash from the account, so the borrower should pay attention to filling in the valid and commonly used bank card number when filling in the bank card information.
