The classification code is the UK clearing code, and SWIFT is the global banking telecommunication system. International remittance should be made through SWIFT system. When the bank remits money to you, you should send a message to the payee's bank through this system. When sending this message, the receiving domain should input the SWIFT code of the other bank to reflect the information of this bank. Moreover, the premise that a bank can send a message to the receiving bank is that it must establish a secret relationship with the other bank, otherwise it can only send a message with a prefix of 9, and the remittance is a message of 202. SWIFT code banks can generally check in official website, but the operator of the branch where you remit money may not have this access right, and the bank is not obliged to help you check. You should ask the other bank. SWIFT code is a BIC with 1 1 digits or letters, which can be split into bank codes. Take China Bank Beijing Branch as an example, and its bank identification code is BKCHCNBJ300, then you can also check whether there is such an arrangement rule code in the information provided by the other party.
