A BIC, or SWIFT, code is a unique, international identifier for banks and other financial institutions. As an example, the Swedish bank Nordea uses the code "NDEASESS". You can find your bank’s code on their website, or by contacting their customer service.
IBAN stands for International Bank Account Number and is the unique, international identifier for your bank account, an example could be "SE35 5000 0000 0549 1000 0003".
With this and the BIC code we will be able to transfer your funds to your bank account. You can find this information in your bank statements or through your bank’s customer service.
