For many Hong Kong businesses, managing international payments is a routine part of their daily operation. This includes settling import and export orders, paying overseas suppliers, or transferring salaries to remote employees and freelancers. However, some new business founders often find terms like IBAN and SWIFT confusing.
In fact, both the international bank account number (IBAN) and the SWIFT code are critical pieces of information in an international transfer. A single typo or missing field can delay the payment by several days or even cause it to fail. This article explains the differences between IBAN and SWIFT, their formats and uses, their roles in international banking systems, and how they help financial institutions complete cross-border payments smoothly.
What is IBAN? An Introduction to the International Bank Account Number
IBAN stands for International Bank Account Number. It is a standardised format used to identify a specific bank account when making or receiving international payments. Its main purpose is to reduce errors by clearly indicating the recipient’s specific bank account, helping to avoid failed transactions due to incorrect or incomplete information.
Originally introduced by European banks, IBAN is now widely used across Europe, the Middle East, and parts of Asia. It plays an essential role in facilitating international money transfers. An IBAN can be up to 34 characters long and includes:
- A two-letter country code (for example, GB for the United Kingdom)
- A two-digit check number for validation
- A bank-specific Basic Bank Account Number (BBAN), which includes the local bank code and account number
For example, GB29 NWBK 6016 1331 9268 19 is a typical UK IBAN. "GB" refers to the country, "29" is the check number, and "NWBK" represents NatWest Bank, followed by the full account number.
The main advantage of IBAN is its ability to pinpoint both the recipient’s bank and specific bank account with accuracy. This is especially useful for international businesses. While banks in Hong Kong do not use IBAN, it is usually required when sending money to Europe, the Middle East, and other regions that support this system.
What is SWIFT? The Global Language of Interbank Communication
SWIFT stands for the Society for Worldwide Interbank Financial Telecommunication. It is a secure global messaging network, known as the SWIFT network, used by financial institutions to send payment and remittance instructions. The system connects banks and enables them to communicate efficiently for cross-border transactions.
When people refer to a SWIFT code, they are talking about the unique identifier assigned by the network to each participating bank. This code is also known as the Bank Identifier Code or Business Identifier Code (BIC). A SWIFT or BIC code is usually 8 to 11 characters long and includes:
- A four-letter bank code
- A two-letter country code
- A two-letter location code
- An optional three-character branch code
For example, HSBCHKHHHKH is the SWIFT or Bank Identifier Code for the Hong Kong and Shanghai Banking Corporation (HSBC). "HSBC" identifies the bank, "HK" represents the country, "HH" indicates the location, and "HKH" specifies the branch.
In countries that do not use IBAN, such as the United States, Hong Kong, and Singapore, the SWIFT code is critical. It serves as the primary address for routing international payments. Even in regions where an IBAN is required, the SWIFT code is often used in conjunction with it to ensure that funds are sent to the correct financial institution.
IBAN vs SWIFT: What Are the Key Differences?
Let’s take a closer look at how IBAN and SWIFT/BIC differ in terms of format, function, and regional use.
IBAN vs SWIFT: Format
An IBAN is an alphanumeric code that can be up to 34 characters long. It includes several elements such as a country code, check digits, bank code, and the account number. For example, a German IBAN might look like this: DE89 3704 0044 0532 0130 00. This sequence precisely identifies the recipient’s specific bank account.
In comparison, a SWIFT code is shorter and more straightforward, typically ranging from 8 to 11 characters. It is made up of the bank code, country code, and branch identifier. For instance, HSBCHKHHHKH represents a branch of HSBC in Hong Kong and helps route the transaction to the correct financial institution.
IBAN vs SWIFT: Function
The primary role of an IBAN is to help identify a specific bank account. It contains detailed information that points directly to the recipient’s account, ensuring that the funds are deposited correctly during an international transfer.
SWIFT codes, on the other hand, are used to identify financial institutions. These codes are assigned by the Society for Worldwide Interbank Financial Telecommunication and are unique to each participating bank. In cross-border transactions, the SWIFT code tells the network which bank should receive the funds.
In simple terms, the SWIFT code tells you which bank the payment is going to, while the IBAN tells you which specific account at that bank.
IBAN vs SWIFT: Regional Use
IBAN is mainly used across European countries and in certain parts of Asia, the Middle East, and Latin America. Over 80 countries currently use IBAN, including all European Union member states and 37 members of the Single Euro Payments Area (SEPA). These regions treat IBAN as the standard for identifying international bank accounts.
SWIFT codes are used globally. Nearly every country involved in international transfers relies on them, including Hong Kong, the United States, Singapore, and Australia. Even if IBAN is not required in a particular region, the correct SWIFT code must still be provided for the transaction to go through.
Before making an international payment, it is important to check whether the recipient’s country uses the IBAN system. If the recipient is in Europe, you will typically need both the IBAN and SWIFT code. If the recipient is in Hong Kong or the United States, the bank code, account number, and SWIFT code are usually sufficient to complete the transfer.
How to Find IBAN and SWIFT Codes
When preparing for an international transfer, it is essential to provide accurate IBAN and SWIFT codes. But where exactly can you find them? Here are the most common and reliable ways to locate these codes.
How to Find an IBAN
If you are sending money to Europe, the Middle East, or other regions that use the IBAN system, the recipient’s IBAN will be required. You can find it using the following methods:
- Check bank statements or online banking: In countries that use IBAN, most banks display the account’s IBAN clearly on monthly statements. Many online banking platforms and mobile apps also list it under account details.
- Ask the recipient directly: If you are the sender, you can request the full IBAN from the recipient. It is best to write it down in uppercase letters and carefully verify each letter and number before proceeding.
- Use an IBAN calculator: If you know the recipient’s bank code and account number but not the exact IBAN format, you can use tools like iban.com or your bank’s IBAN calculator to generate it. However, you should always confirm the generated IBAN with the recipient to ensure accuracy.
How to Find a SWIFT Code
SWIFT codes are assigned by the Society for Worldwide Interbank Financial Telecommunication and are required for nearly all international payments. You can find a bank’s SWIFT code using the following methods:
- Check the bank’s official website or online banking platform: Most banks list their SWIFT codes on their websites, often indicating which branch uses which code. If you are the recipient, you may also find the SWIFT code in your online banking profile.
- Contact the bank directly: If you are unsure about the correct branch code, call the bank’s customer service hotline or visit a branch to confirm the SWIFT code.
- Use the SWIFT directory tool: The official SWIFT directory allows you to search for a bank’s SWIFT or BIC code by entering the bank name, country, and city. This is one of the most reliable ways to ensure you have the correct code.
- Request the code from the recipient: If you are making a payment overseas, ask the recipient to provide their correct SWIFT code to avoid delays or rejections caused by intermediary banks.

Frequently Asked Questions
Is an IBAN the same as a SWIFT code?
No, they are different. In essence, IBAN identifies overseas bank accounts, while a SWIFT code identifies the bank itself.
Can I use an IBAN instead of a SWIFT code?
No, as both codes serve different purposes. Depending on the destination country, you may be required to provide both the IBAN (to specify the recipient's individual bank account) and the SWIFT code (to identify the recipient's bank or branch) when making international financial transactions.
Is SWIFT better than IBAN?
You cannot compare SWIFT and IBAN codes directly, as most international transfers require both. Each code plays a distinct role, but together they help ensure accurate and efficient international bank transfers.
