What is an IBAN?

An IBAN (International Bank Account Number) is a unique number used to identify a customer’s bank account. Not all countries use IBANs, but for some countries an IBAN is required when sending international wire transfers.

The structure of an IBAN will vary by country – but it will always start with a 2-letter country code (e.g., VG for British Virgin Islands, GB for Great Britain, etc.).
