What Is An IBAN, And How Does It Function?

  • 22-September-2021

An IBAN or International Bank Account Number is a unique identification code for accounts at financial institutions worldwide. They are used to facilitate cross-border transactions and eliminate potential errors in wire transfers to foreign countries. The IBAN consists of an ISO country code, check digits, and a bank account number. It should be displayed on any international money orders issued by a bank. The IBAN's function is similar to the SWIFT code, and it serves as an equivalent to the routing number used in domestic transfers worldwide.

How Does An IBAN Help With International Transactions?

The country code, check digits, and account number work together to correctly identify a financial institution that holds an account belonging to a customer. The country code eliminates the risk of ambiguity for an international transaction since many countries and financial institutions have similar names. Similarly, check digits improve the integrity of IBAN by ensuring that all characters in the IBAN are correct. Lastly, the bank account number is used to identify an account at a specified financial institution.

What Does An IBAN look Like?

An IBAN has a series of alphanumeric characters, representing an important part of the money transfer process. The format is always the same for every country; however, different numbers denote how many digits it will use (Norway uses 15 and Liechtenstein uses 21). No matter what country you're from or where your recipient lives, their bank account must be able to decode this tricky code! IBANs are in a string of crazy-long digits that can be hard to keep track of. But, they're actually broken up into the following parts:
  • Country code (2 or 3 letters), and check digit code that which is used as an error checking device and looks something like "X" followed by nine numerals from 0 to 9,
  • Bank identifier codes made up of two alphanumeric characters that identify your financial institution, such as CH for Swiss Confederation;
  • Branch codes with four numerics indicating where you want funds transferred if needed, along with the account number consisting of only 4 digits, so don't sweat it!

IBAN vs. SWIFT Codes

The banking system is complicated, and it can be difficult to keep track of which account numbers are being used in what countries. That's why there was an agreement between the Society for Worldwide Interbank Financial Telecommunication (SWIFT) and International Bank Account Number (IBAN). The SWIFT code identifies each bank branch and country-specific information, whereas IBAN provides a shortened version that doesn't need additional data like routing or transit codes. The difference between these two methods lies in how they identify funds and different pieces of info needed when transferring money from one country to another - but both have been deemed internationally recognized by means such as their use on international transactions through banks across various locations worldwide. The SWIFT system is a messaging service developed in the early 1970s, predating attempts to standardize international banking transactions through IBAN. Banks can use this pre-existing and standardized infrastructure for financial communications by exchanging messages with other banks using their own language formats (MT199). This means more than 80% of all cross-border payments are made on the SWIFT network, making it one of the most critical parts of global finance today.

How Does An IBAN Differ From A BIC?

The International Bank Account Number (IBAN) and the BIC (Bank Identifier Code) are two different acronyms that serve entirely different purposes. The IBAN is for international bank transfers, while the BIC identifies banks or other financial institutions in a country. While these may seem interchangeable at first glance due to their similar abbreviations, they have subtle differences that can cause major issues if not properly addressed! For example, your full account number might be necessary when wiring money internationally, depending on where you're sending it from; but only your bank identifier code will suffice if transferring domestically instead -- so pay close attention!

How Do You Find Your IBAN?

Finding your account’s IBAN is a simple process that can be done by looking in two places. The first place to look for the information is on the checkbook but you should also try checking online bank statements to see if there's an IBAN listed on them as well. If neither of those options works out and you're still unsure about how to find it, contact customer service at your financial institution, who will happily help track down this piece of critical data!

What Is The Purpose Of IBAN?

Ever since the days of ancient Greece, people have been making international transactions. However, different countries had their own formats for bank account numbers which led to errors in cross-border transfers and other financial dealings because computers could not decipher them all. In 1997 the International Organization for Standardization proposed a new system to solve these problems - ISO 13616-2:2007 (IBAN). The IBAN program has solved many issues with wire transfer accuracy due to its uniformity across borders. It will continue doing so as more countries come on board and adopt it themselves.

What is an IBAN Registry?

The IBAN Registry can be a helpful resource for any international financial institution that needs to send or receive payments abroad. This registry, published by SWIFT and containing the details of each country's IBAN format, is an invaluable tool when it comes to complying with today’s standards and keeping up-to-date on what new countries are being added in the future. For those in the banking or international trade industries who need assistance understanding how best to communicate across borders to comply with modern regulations while also staying informed about changing technologies.  You'll find countries such as Hungary under the "European Union" tab, where you can look up specifics like their currency code (HUF) and whether they use postcodes or not ("Y").


The IBAN gives you a number that lets you identify your bank account in any country. It can be used for interbank transfers between different countries, keeping the complexity of international transactions as low as possible while also providing an effective way of transferring money internationally comparatively quickly!
