Currency ISO Codes
Currency conversion and currency iso codes
Currency ISO codes (ISO 4217) is an industry standard to uniquely identify a particular currency from all the existing ones. Popular codes like USD or GBP are well known by most of the public, while many of them are widely unknown, especially those from developing countries.
Currency codes also reflect history and political changes. Some of them belong to currencies from the past, like German Mark (DEM) which after their integration to the European Union adopted the Euro (EUR).
The following table also shows the pegged and historical currencies.
