A sort code is a six-digit number used in the United Kingdom (and formerly in Ireland) to identify a specific bank and its branch. It is usually formatted as three pairs of numbers, for example, 12-34-56. The first two digits typically identify the bank, while the last four digits specify the particular branch where the account is held
. Sort codes are essential for routing money transfers between financial institutions domestically within the UK. They help banks verify where a money transfer is coming from and where it is being sent to, ensuring accurate and efficient transactions
. Sort codes differ from account numbers: the sort code identifies the bank and branch, while the account number uniquely identifies an individual’s bank account within that branch. Both are required for making or receiving payments
. Sort codes are printed on debit cards, bank statements, cheque books, and are available via online banking. They are safe to share for receiving payments, as they cannot be used to withdraw money from an account
. In summary:
- Six-digit number formatted as three pairs (e.g., 12-34-56)
- Identifies the bank and branch of the account
- Used for routing domestic UK payments
- Different from the unique account number
- Found on debit cards, statements, and online banking
- Safe to share for receiving payments
This system is unique to the UK and was historically used in Ireland but has been largely replaced there by SEPA systems
. Other countries use similar codes with different names, such as routing numbers in the US or BSB numbers in Australia
