A sort code is the six-digit number, written like 12-34-56, that identifies a UK bank and branch. Together with an eight-digit account number, it tells a payment exactly which account to go to.

What the digits mean

The first digits usually identify the bank, and the rest the branch or the part of the bank that holds the account. Many app-only banks and money apps have their own sort codes, even without branches.

Sort code, account number and IBAN

For payments within the UK, a sort code and account number are all you need. For payments from abroad, the payer usually needs your IBAN, which contains your sort code and account number inside it, plus a country code and check digits.

Confirmation of Payee

When you set up a new payee, most UK banks check that the name you enter matches the name on the account. If it doesn't match, you'll see a warning before you send, which helps stop mistakes and scams.
