Locating Your IBAN
If your bank is international, you can locate your IBAN on your bank statement online or in paper form. Your IBAN will look different from other numbers as it will contain up to 34 alphanumeric characters, starting with your country's International Organization for Standardization country code. Your IBAN can also be found in the SWIFTRef online directory. According to HSBC, the IBAN includes your country code, check number, sort code and bank code.
Uses for Your IBAN
IBANs are used in international personal banking transactions. Wells Fargo recommends adding the IBAN in the account number field when transferring international funds online, since the account number is included within the IBAN. Although bank customers within the United States do not have an IBAN, they will need the IBAN for international recipients of their funds. To know if your recipient comes from a country that requires an IBAN, the Society for Worldwide Interbank Financial Telecommunication and Nordea have online directories of the countries that participate in the IBAN registry.
