The main reason is that this bank code belongs to the head office, and more than 2 10 branches have SWIFT codes, so it is impossible to identify the bank without writing down the specific branch SWIFT codes. Please attach the specific branch name and account number. If it still doesn't work, ask your customer to specify the Swift of the branch where he opens an account, mainly three X's followed by a specific three-character code, so that the remittance can be made.
