If you’re doing business with international suppliers, it’s important you understand exactly how to pay them. Some countries require the use of an IBAN number.
What is an International Bank Account Number (IBAN)?
IBAN, or International Bank Account Number, is a code you can use to make or receive international payments. Your IBAN code is different from your account and sort number–it’s used to help overseas banks identify your bank account so you can receive or send international payments, and used for domestic/regional payments in IBAN countries.
Your IBAN code includes numeric identifiers, such as a bank account number and a country code, that identify your bank and account to international banks.

Main Points
- IBAN is short for International Bank Account Number and is used to identify an individual bank account in cross-border payments.
- IBAN codes facilitate international money transfers.
- SEPA is a euro payment area that uses IBANs for euro transfers across participating European countries.
- An IBAN can be located on your bank statement, through online banking, an IBAN calculator, or the IBAN Registry
- The SWIFT network is the registration authority for standardized formats for the IBAN system and administers the ISO 9362-defined BIC system.
What Does an IBAN Look Like?

In general, an IBAN number is divided into a numbering system comprised of codes (sometimes in the order presented, although it does vary by country):
- Country code (sometimes called location code)
- Check digit code
- Bank identifier code
- Branch code
- Account number
The last three (bank, branch, and account numbers) collectively make up the Basic Bank Account Number (BBAN) and are used to locate a specific bank.
The IBAN format is the same across countries, although the number of digits may vary. For example, Norway uses 15 characters, while Liechtenstein uses 21. The maximum number that any country can use is 34.
Please note that the IBAN method is used in most European Union countries and other European countries. Always check with your bank if you’re unsure about an international transfer.
IBAN vs BIC
A Bank Identifier Code (BIC) is just a general term for a SWIFT code. That’s why you sometimes see the terms paired together as SWIFT/BIC. Technically, the financial messaging network through which international transfers are sent is the SWIFT network, and the codes are BIC codes.
Whereas an IBAN identifies a bank’s country of business and one’s precise account number within that institution, a BIC (Bank Identifier Code) is 8 or 11 characters, with 3 specific elements to aid a transaction. BIC is composed of alphanumeric characters: a 4-letter bank code, a 2-letter country code, and a branch identifier consisting of an optional 3-character branch code.
A BIC is also important to avoid post-transaction costs associated with correcting a misdirected wire transfer.
IBAN vs SWIFT Code
IBAN vs. SWIFT codes are both internationally recognized for identifying bank accounts when a transfer is being made. The unique identifier required depends on the country involved and the recipient’s bank.
SWIFT stands for the Society for Worldwide Interbank Financial Telecommunication. A SWIFT code refers to a specific financial institution in an international transaction, whereas an IBAN number identifies an individual account and the country of business. It’s the global equivalent to a bank account and an ABA routing number in the United States.
The primary difference between the two codes lies in the information inside.

How to Find Your IBAN Number
The IBAN is located on every paper bank statement an institution prints. It may also appear inside your web-based account if you use online banking. If you can’t find it in either of those locations, contact the bank, use the IBAN Registry, or an IBAN calculator tool.
Does it Cost Money to use an IBAN?
IBANs are needed for international bank transfers, so expect to pay bank transfer fees. The cost will vary by country and exchange rate, but there is usually a processing fee and commission charged.
Main Functions of an IBAN Number
When it comes to international banking, IBANs are a critical piece of information. It serves three main functions for sending and receiving cross-border payments, which are:
- Allows banks and other financial institutions to quickly note the country of origin for the bank.
- IBAN pinpoints the exact account number to which the money will be sent.
- It’s an easy way to double-check the accuracy of a bank’s details and ensure a transfer will be successful.
Which Banks Use IBAN Numbers?
This all depends on where you live. Banks in the United States, Canada, Australia, New Zealand, and China do not use IBAN codes. They use SWIFT codes and routing numbers. IBAN is widely used across Europe and in many countries in the Middle East, Caribbean, Africa, and other regions.
According to the ECBS (European Commerce Banking Services), “generation of the IBAN shall be the exclusive responsibility of the bank/branch servicing the account”.
The Basic Bank Account Number (BBAN) format is decided by the designated payment authority, or central bank of each country, and there is no consistency in which formats are adopted. They may register the BBAN format with SWIFT, but countries are not obliged to do so. The same goes for IBAN numbers. A major difference between the two is that under SWIFT, there is no requirement that BBANs be a certain length.
What is the IBAN Registry?
The IBAN registry is a catalog of those countries that are compliant with the most recent IBAN standards (ISO 13616). The registry, published by SWIFT, contains details of each country’s IBAN format.
The registry also shows the document’s update history and gives a brief description of important terms used in IBAN transactions.
Is an IBAN Number Used in the USA?
IBAN numbers are used only in the USA to send money to a foreign bank account that participates in the International Bank Account Number System. Currently, US banks do not use IBANs domestically. Instead, US banks use ABA routing numbers (for domestic transfers) and SWIFT codes (for international transfers).
What Is the Difference Between IBAN and SEPA?
The Single Euro Payment Area (SEPA), as the name suggests, is a payment network in Europe that provides digital transfers within the European Union. This includes places like Spain, Ireland, Hungary, the United Kingdom, and more. It also covers a few countries outside of the union, including Norway, Iceland, Switzerland, and Liechtenstein.
It’s overseen by the European Committee for Banking Standards (ECBS), which helps set national standards for business identifier codes.
In total, the SEPA network works across 41 countries and territories. By comparison, over 89 countries currently use the IBAN system, according to the SWIFT IBAN registry. Multiple currencies can also be sent via IBAN, whereas only Euros can be sent via the SEPA network.
Since its adoption throughout Europe in the late 1990s, some countries in the Middle East and the Caribbean have also begun using the IBAN system for digital money transfers.
What is the Purpose of IBAN?
Before International Bank Account Numbers were adopted, European countries used different bank account number formats, leading to errors in cross-border transactions. International payments would end up in the wrong location, requiring extra fees and time to resolve the issue.
Then in 1997, the International Organization for Standardization (ISO) proposed a new system of global money movement. Today, this international standard is known as ISO 13616-1:2020.
The result of the IBAN program has been fewer errors in international wire transfers and other financial transactions. Because multiple countries now operate within the same system, it’s also easier for people to send money from one jurisdiction to another.
Despite these advantages, there are issues IBAN cannot address, such as foreign exchange rates.
Beyond IBAN: Simplifying International Payments at Scale
An IBAN is an important part of cross-border payments, but it’s only one piece of the process. As businesses expand internationally, finance teams often need to manage IBANs, SWIFT codes, local banking requirements, tax documentation, currencies, and payment regulations across dozens of countries.
While IBANs help reduce errors, payment failures can still occur when supplier banking information is incomplete, outdated, or entered incorrectly.
The Challenge of Managing Global Supplier Payments
For organizations managing large supplier networks, collecting and maintaining banking information manually can create significant operational risk and administrative overhead. Spreadsheets, email chains, and country-specific payment requirements make it difficult to ensure banking details remain accurate and up to date.
That’s why many companies automate supplier onboarding, banking validation, and global payment workflows. Instead of relying on manual processes, finance teams can centralize supplier information, verify banking details before payments are sent, and streamline international payments from a single platform.
Whether you’re paying a handful of overseas suppliers or managing a global payment operation, understanding IBANs is the first step. Building scalable processes around them is what helps finance teams reduce errors, improve efficiency, and support international growth.

IBAN FAQs
Is it safe to give out an IBAN number?
It is generally safe to share your IBAN when needed to receive a payment, but you should only share banking details with trusted parties and avoid sending them through unsecured channels.
Is a SWIFT code the same as a routing number?
The SWIFT system is used by international organizations, whereas routing numbers are used only in the US.
Who uses IBAN codes?
As of December 2025, 89 countries are using the IBAN system.
Should I use BIC or IBAN?
If you’re using the IBAN system, you’ll need both. While an IBAN provides data about your individual account, the BIC code is the bank where your account is held.
