A sort code is part of a bigger picture
In Ireland and the UK, the national sort code and account number are embedded inside the domestic bank account number, which in turn sits inside the IBAN.
Common questions about sort codes
What is a National Sort Code (NSC)?
It's a six-digit code, usually written as three pairs of digits, that identifies a specific bank and branch in Ireland or the United Kingdom, similar to a routing number elsewhere.
How is a sort code different from a BIC or IBAN?
A sort code identifies the branch domestically. A BIC/SWIFT code identifies the bank internationally. An IBAN is the full international account number, and for Irish and UK accounts, it embeds the sort code inside the BBAN.
Do you cover sort codes outside Ireland and the UK?
No, national sort codes are specific to Ireland and the UK. For other countries, look up the bank directly from the country directory.
Can I validate a full IBAN instead of just the sort code?
Yes, use the free IBAN checker to validate the whole account number, including its checksum and bank details, in one step.
