What is a sort code?
Sort code is a 6-digit UK bank branch identifier used for bank transfers.
A sort code identifies the UK bank branch for your account.
It is usually shown as three pairs of digits, e.g. 12-34-56.
Customers need sort code and account number to pay by bank transfer.
Guidance only. Confirm bank details before sharing invoices to avoid failed or misdirected payments.
