What Is an International Bank Account Number (IBAN)?
Let me explain what an IBAN is directly to you: it's an international bank account number that identifies the country of origin for transactions involving foreign bank accounts. You use it alongside a standard bank account number when the transaction comes from a foreign bank.
The IBAN begins with a two-digit country code, followed by two numbers, and then several more alphanumeric characters. This setup is an internationally accepted standard for pinpointing transactions with foreign accounts. European banks created it to make international transactions easier, and it also verifies that your transaction details are correct.
How International Bank Account Numbers (IBANs) Work
Here's how an IBAN functions: it includes a two-letter country code, two check digits, and up to thirty-five alphanumeric characters known as the basic bank account number (BBAN). Each country's banking association decides the BBAN standard for their accounts.
You'll encounter an IBAN when sending interbank transfers or wiring money between banks, particularly across borders. In countries using the IBAN system, examples include Albania's AL47 2121 1009 0000 0002 3569 8741, Cyprus's CY17 0020 0128 0000 0012 0052 7600, Kuwait's KW81 CBKU 0000 0000 0000 1234 5601 01, Luxembourg's LU28 0019 4006 4475 0000, and Norway's NO93 8601 1117 947.
Importantly, the U.S. and Canada do not use the IBAN system themselves, but they recognize it and process payments accordingly.
IBAN Example
An IBAN can have up to 34 alphanumeric characters, broken down into the country code (ISO standard for the participating country), check digits from the issuing institution, a bank identifier (which might include branch details), and the BBAN that specifies the individual account.
For instance, a hypothetical IBAN for a bank in Finland would be FI21 1234 5698 7654 3210, where FI is the country code, 21 are the check digits, 123456 is the bank identifier, and 9876543210 is the BBAN.
IBAN vs. SWIFT Codes
You should know there are two main standardized methods for identifying accounts in international transfers: IBAN and SWIFT codes. The key difference is that SWIFT identifies the specific bank, while IBAN identifies the individual account.
Both are crucial for smooth international finance. SWIFT came first and is still used for most transfers because it allows sharing detailed financial data like account status, amounts, and transfer details. Banks often use BIC interchangeably with SWIFT, both being 8 to 11 characters of letters and numbers.
Requirements for IBANs
IBAN emerged from varying national standards that caused misinterpretations in payments. The ISO published ISO 13616:1997 to address this, followed by a refined version from the European Committee for Banking Standards that used only uppercase letters and fixed lengths per country.
Updates in 2003 and 2007 made it more facilitating for international data processing without specifying internal procedures like file organization or languages.
Who Uses an IBAN?
IBAN started for electronic payments between European banks and has since gone global, though not everywhere. If you're in North America, Australia, or Asia, you won't use IBAN for domestic transfers, only for sending to IBAN-adopting countries, possibly falling back on SWIFT.
Why Was IBAN Created?
It was created to cut down on errors, rejected payments, delays, and fees in cross-border payments by improving verification.
What Does an IBAN Number Look Like?
An IBAN has up to 34 alphanumeric characters: a two-character country code, two check digits, and a BBAN with bank and branch codes varying by country.
How Can I Get an IBAN?
If you're a customer in an IBAN region, request one from your bank. Remember, it's only for receiving payments, not for withdrawals.
The Bottom Line
IBAN is specifically for international transfers. As of the July 2023 registry, 86 countries use it. If your country doesn't, you might use SWIFT instead. These systems exist to make international money movement less complicated.
