Sort Code Vs Swift Code: What Is The Difference

by MonieWorld • 2025-11-26 • 8 min read

Thousands of transactions come in and out of a bank every day. For these transactions to be fulfilled, the banking system needs to know which branch they are coming from and to which bank they are going to.

Sort codes and SWIFT codes are both identification methods that UK banks use to determine where money is paid from or where it should be sent.

While both serve a similar purpose, there is a big difference between them. The sort code is used for domestic transfers, while the SWIFT code is designed for international transactions.

Understanding these two codes, how they work, and when to use them is crucial for ensuring that your transfers arrive at the correct account, whether you are sending them within the UK or internationally.

This article clearly explains these codes, outlining their purpose and demonstrating when to use each.

Understanding Sort Codes

A sort code is a six-digit number used in the UK and Ireland to identify specific bank branches for domestic transactions.

It's like a unique signature that helps your bank determine the exact bank to which you intend to send funds when you initiate a transfer.

It works in conjunction with an account number, which identifies the account from which you send money or receive funds.

A key thing to remember with sort codes is that they are solely for inter-country transactions.

This means you cannot use this code alone to transfer money between two countries, even Ireland and the UK, as it lacks the appropriate code to identify the country.

Decoding the Sort Code

Your bank's payment system will automatically interpret the sort code to process your transaction.

However, decoding bank codes can be handy in certain banking activities, such as troubleshooting transfer issues or verifying account details.

In decoding the sort code, you'll first notice that it is presented as three pairs of digits.

The first two digits represent the bank name, such as Lloyds Bank as a whole, and the last four digits identify the specific branch of the bank, such as Lloyds Bank in Yardley.

Let's use a simple illustration. If 12-34-56 is the sort code of your bank.

It would be interpreted as;

Your bank name: 12

Specific bank branch: 3456

Several free online tools allow you to enter a sort code and return information about the corresponding bank and branch. Some popular options include:

  • Pay.UK Sort Code Checker
  • SortCodes.co.uk

Additionally, many banks have their own online tools or branch locators that you can use to find information about a specific sort code. You can usually find these tools on the bank's website.

How to Use The Sort Code

When making domestic payments, such as direct debits and interbank transfers, you will need to provide the recipient's sort code and account number.

The bank payment system will use this sort code to:

  • Identify the recipient's bank.
  • Locate the specific branch.
  • Direct the transfer to the correct bank and branch.

Similarly, when someone wants to pay you, they will require your sort code to direct the payment to you.

Always ensure you provide the correct sort code.

Understanding SWIFT Codes

Also known as a Bank Identifier Code (BIC), a SWIFT Code is an international standard for identifying banks worldwide, enabling secure international wire transfers.

You can easily spot this code on your bank statements. It is an 8 or 11 alphanumeric code consisting of the shortened version of your bank's name, followed by the country code and branch information.

When sending money to someone in a different country, you'll typically need their SWIFT code, along with their International Bank Account Number (IBAN).

SWIFT and IBAN are the two globally recognised standard systems for identifying accounts when executing bank transfers between countries. While the SWIFT number is crucial for identifying the bank itself, IBAN identifies specific bank accounts across borders.

SWIFT is an association (Society for Worldwide Interbank Financial Telecommunication) that connects over 11,000 member banks worldwide, helping them execute international payments with lower costs and greater security.

Financial institutions prefer it because it allows them to share other messages, such as payment instructions and confirmations, across financial data in a secure network.

Interpreting a SWIFT code

If an international transfer fails, the SWIFT code might be one of the pieces of information you need to investigate the problem with your bank or the recipient's bank. In such a case, here's how to interpret it.

Format: Comprises 8 or 11 alphanumeric characters:

Example: AAAABBCCDD.

Bank Code ("AAAA"): The first four letters denote the bank name and are usually an abbreviation of the represented as the bank.

Country Code ("BB"): 2 letters indicating the country.

Location Code ("CC"): 2 characters (letters or digits) specifying the location.

Branch Code ("DD"): Optional three characters for the specific branch.

Usage: Essential for international transactions to ensure funds reach the correct financial institution globally.

Sort Codes vs SWIFT Codes: Key Differences

Sort codes and SWIFT codes are both used to identify banks and facilitate money transfers; however, they serve different purposes and operate in distinct contexts.

Areas Sort Code SWIFT Code
Geographical application UK and Ireland Global
Functionality Identifies specific bank branches to route domestic payments Identifies banks worldwide for cross-border transactions
Format Numeric, six digits formatted as XX-XX-XX Alphanumeric, 8 or 11 characters

Appropriate Usage of Sort Codes and SWIFT Codes

Whether you're using a sort code or a SWIFT code, absolute accuracy is key. A single incorrect digit in a sort code can send your money to the wrong account, and recovering it can be challenging.

Another thing to consider for optimum usage is the transaction fee, particularly with SWIFT transfers. They often come with higher costs and can sometimes take longer due to the involvement of intermediary banks. If you're sending money to a country within a shared economic zone, consider exploring other options, such as the Single Euro Payments Area(SEPA).

Sort Codes: For domestic transactions within the UK and Ireland, such as setting up direct debits or transferring funds between local accounts.

SWIFT Codes: For international transactions, including sending or receiving money across different countries.

Locating Your Bank's Sort Code and SWIFT Code

If someone needs to send you money, they'll ask for your bank details, including your account number, sort code, and SWIFT codes if they are sending from outside the UK. Here are the common places you can check for these codes:

Sort Code: Typically found on bank-issued cards, statements, and via online banking platforms.

SWIFT Code: Available on bank statements, through online banking, or by contacting the bank directly.

Just as poorly addressing a letter can prevent the postal service from delivering it to your recipient, using the wrong bank codes may result in funds being deposited into the wrong account.

Always remember the difference between crucial bank codes, such as the sort code and SWIFT codes. The sort code is for UK banks, while SWIFT codes are for international transactions. This simple cue will help you avoid errors and ensure efficient financial transactions, both domestically and internationally.

FAQs

1. Can I use a sort code instead of a SWIFT code?

No, sort codes cannot be used in place of SWIFT codes. Sort codes are 6-digit codes that help UK banks identify bank branches for payments within a country, while SWIFT codes are identifiers used for cross-border transactions.

2. Do you need a sort code for an international transfer?

Yes. It is advisable to use a sort code in conjunction with the SWIFT code for international transfers. While the SWIFT code identifies the bank globally, the sort code pinpoints the specific branch within that bank, ensuring smooth money transfers.

3. How do I know my SWIFT code?

You can look up your bank's SWIFT code in your bank account statements or log into your online banking account. You can also contact your bank directly to obtain your SWIFT code.
