IBAN stands for International Bank Account Number, which you can use when making or receiving international payments.
Your IBAN doesn't replace your sort code & account number - it's an additional number that contains extra information to help overseas banks identify your account for payments.
A SWIFT code (or SWIFTBIC, as it's sometimes known) is a code that helps overseas banks identify which bank to send money to. For example, if an overseas bank is sending a payment to your Card One Money account, they'll need to know our SWIFT code.
Your IBAN & SWIFT number is displayed in the sign in area of your online access.
