Where to find your IBAN

It's important that you use the right IBAN when sending money. If you get it wrong, your bank might send your money to the wrong destination, or it may charge you for an invalid payment.

You can usually find your IBAN by logging into your online banking, or checking your bank statement. You can also use the tools on this site.

It's important to remember that an IBAN being in the right format isn't guarantee that it exists. Or that it's the right IBAN for a particular account. You should always check it with your recipient or bank before sending or receiving a payment.

Routing numbers, SWIFT codes, BIC and IBANs – what’s the difference?

You’ll need a few details to send or receive a transfer – either domestically or internationally.

IBANs (international bank account numbers) identify individual bank accounts. They're issued by many banks in Europe, but banks elsewhere in the world are starting to adopt them as well.

Routing numbers help identify banks when processing domestic ACH payments or wire transfers. But only in the United States. You don't need one to make a payment to your friend in France, for example.

SWIFT codes, like routing numbers, also identify banks and financial institutions. This time for international payments. They're sometimes known as BIC codes.
