Money can be transferred in a multitude of different ways: from paying a vendor for goods and services, to using a mobile app to send funds to a friend; and some transactions require more information than others. Unlike a contactless purchase in a restaurant or store, arranging a money transfer from one country requires specific details.

In this guide we will look at the differences and similarities between sort codes and SWIFT codes, in a bid to lift the lid on the common types of banking jargon likely to emerge when making cross-border transactions.

What is a sort/SWIFT code?

Sort codes

Sort codes are used by British and Irish banks to identify the location of a domestic bank, so that financial institutions can recognise where the payment has originated from or validate where it is being sent to. Also known as sorting codes, or a national sort code (NSC) in Ireland, these codes can be found integrated into an IBAN (International Bank Account Number) but they have no relation to SWIFT or BIC codes.

SWIFT codes

SWIFT codes are created by the Society for Worldwide Interbank Financial Telecommunication network. They are used to identify the bank location, country, and branch number when initiating an international transfer.

A SWIFT code is an alternate format of a BIC (Bank Identification Code) and the terms are interchangeably used.

What is the format of a sort/SWIFT code?

Sort codes

Sort codes are made of 6 numbers, divided into 3 pairs, for example: 12-34-56

SWIFT codes

SWIFT codes are a bit more complicated as they can range from 8 to 11 alphanumeric characters. These characters are divided into different subcategories: bank name, country, address and bank branch. 

For example: AAAABBCCDDD

AAAA: Bank code. These 4 letters usually look like a shortened version of the bank name

BB: Country code. These two letters represent the country the bank is in

CC: Location code. These two characters will indicate where the bank’s head office is located

DDD: Branch code. The last three characters will indicate the specific branch of the bank

How do sort/SWIFT codes work?

Sort codes

Sort codes are used by domestic banks and financial institutions only. They work by identifying accounts and providing instructions needed to route money transfers domestically within clearance organisations.

SWIFT codes

When a payment is sent via the SWIFT network, messages are passed between banks (as well as non-bank financial corporations) in a secure, encrypted way. Funds are not physically transported using the SWIFT network, only the instructions; this communication facilitates the money transfer.

Who uses sort/SWIFT codes?

Sort codes

Sort codes are used by UK and Irish banks only; they are only used for international transactions when the payment is sent via bank transfer.

SWIFT codes

SWIFT codes are used by 212 countries, all of whom utilise the SWIFT network. Over  11,000 financial institutions use this network; banks, foreign exchange brokers, clearing houses, depositories, brokering institutes, trading houses and asset management companies.

Where can I find a sort/SWIFT code?

Sort codes

Sort codes can be found on bank-issued cards, statements and via online banking. For customers still using cheque books, sort codes are also printed here as well.

SWIFT codes

SWIFT codes can be found on bank statements and by logging into online banking accounts. Alternatively, customers can contact the bank directly to confirm the SWIFT code.


We hope this guide has proven helpful and eradicated any confusion users may be experiencing when locating the specific banking details required for certain money transfers. To summarise: sort codes will only be required for domestic bank transfers sent between British and Irish account holders, or when sending money to the UK or Ireland from abroad; SWIFT codes, however, are used to identify a bank account when verifying an international money transfer.
