SWIFT code VS routing number VS IBAN

It’s normal to get confused by all the acronyms and codes involved in (international) wire transfers. These three, SWIFT code, routing number, and IBAN are the most common ones, and it's important to know what each one means.

We’ve already explained what’s a bank routing number and it’s also worth mentioning that they’re only used in the US. So, if you have a US bank account and want to make a domestic wire transfer, you'll need the routing number of the recipient’s bank.

A SWIFT code (also called BIC) is used for the identification of banks and financial institutions globally when making international money transfers. This code will identify the country, bank, and branch of the recipient's account. If you’re the one making an international transfer to a beneficiary outside the US, you’ll need to enter the SWIFT code of the beneficiary’s bank. If you’re the one receiving an international transfer, you’ll have to provide your bank’s routing number, as well as its SWIFT code.

While a routing number and a SWIFT code are both numbers used to identify a specific financial institution, an IBAN is a personal bank account number. It is generally used for international transfers in Europe and several other territories. It is not used in the US (as well as in Canada, Australia, and New Zealand). So, if you’re sending or receiving an international transfer from Europe (and several other territories), you will need an IBAN.
