How Is an IBAN Structured?
An IBAN begins with a two-letter country code (like DE for Germany or GB for the United Kingdom), followed by two check digits used for error detection, then the domestic bank and account number. The total length varies by country — German IBANs are 22 characters, British IBANs are 22, and some countries use up to 34. The check digits help prevent transcription errors in international transfers.
Do U.S. Banks Use IBANs?
No. The United States does not use the IBAN system. U.S. banks use routing numbers and account numbers for domestic transfers and SWIFT codes for international transfers. If a foreign bank or company asks for your IBAN and you have a U.S. account, provide your SWIFT/BIC code and account number instead. This is a common point of confusion for international transactions.
What Is the Difference Between an IBAN and a SWIFT Code?
An IBAN identifies a specific bank account and is used mainly in IBAN-adopting countries. A SWIFT code (also called a BIC) identifies the bank itself and is used worldwide for international wire transfers. Many international transfers require both — the SWIFT code routes the payment to the correct bank, and the IBAN directs it to the specific account within that bank.
Frequently asked questions
Where can I find my IBAN?
Check your bank statement, online banking portal, or contact your bank directly. In countries that use IBANs, it is typically displayed prominently in your account details. Banks can also provide your IBAN over the phone or in person with proper identification.
What happens if I enter the wrong IBAN?
The check digits in an IBAN catch most transcription errors before the transfer is sent. If an incorrect but valid IBAN is submitted, the funds may be sent to the wrong account. Recovery in that case is difficult and depends on the receiving bank's cooperation.
