Some online lists of currency codes still use old codes - so check here if you're uncertain about which codes to include in your currency conversion project.

Please note that ISO 4217 codes can be deprecated and replaced over time. Wherever you see a currency code field in our API documentation you must supply one of the codes from this list. The 'Currency Code' field you see at the start of each line below is the ISO 4217 Three Letter Currency Code for that currency.
