ISO 4217

An airline ticket showing the price in the ISO 4217 code

ISO 4217 ISO 4217 is a standard first published by International Organization for Standardization in 1978, which delineates currency designators, country codes (alpha and numeric).

The ISO 4217 code list is used in banking and business globally. In many countries the ISO codes for the more common currencies are so well known publicly that exchange rates published in newspapers or posted in banks use only these to delineate the currencies, instead of translated currency names or ambiguous currency symbols. ISO 4217 codes are used on airline tickets and international train tickets to remove any ambiguity about the price.
