How a sort code works
A sort code is a six digit number that identifies the bank and the branch where a United Kingdom account is held. It is usually shown as three pairs of digits separated by hyphens or spaces, for example 12 34 56, with the leading digits identifying the bank and the remaining digits identifying the branch. When a payment is sent within the United Kingdom, the payment network uses the sort code together with the eight digit account number to route the money to the correct account. The sort code appears on cheques, bank statements, and in online banking, current as of 21 March 2026.
Sort code and account number
In the United Kingdom a domestic account is identified by two numbers used together: the sort code, which points to the bank and branch, and the account number, which is usually eight digits and identifies the individual account at that branch. Both are needed to send a Faster Payment, set up a direct debit or standing order, or receive a salary or supplier payment. For international payments, the same account is instead identified by an IBAN and a SWIFT BIC code rather than a sort code.
Why it matters to a business
A business shares its sort code and account number so customers and other businesses can pay it, and uses a supplier's sort code and account number to pay them. Entering the wrong sort code can send a payment to the wrong bank or branch, so many banks offer a confirmation of payee or name check that compares the account name with the sort code and account number before a payment is sent. A business should confirm a new payee's sort code and account number directly with that party and use any name check the bank provides.
