Sort code

A sort code is a 6-digit numerical code used in the United Kingdom and Ireland to identify a specific branch of a bank or building society. It is generally used in conjunction with an account number to uniquely identify an account for the purposes of making or receiving payments. The sort code is divided into three pairs of digits. Banks use the sort code to route funds transfers between different accounts, and it is a key element in the UK and Irish banking system. The system helps to ensure payments are directed to the correct bank branch. The sort code also allows for identification of the specific bank and branch involved in a transaction. While similar to routing transit numbers in other countries, it's specifically used for identifying bank branches in the UK and Ireland. Incorrect sort codes can lead to payment delays or failures.
