ISO 4217 is a standard published by International Organization for Standardization, which delineates currency designators, country codes (alpha and numeric), and references to minor units in three tables:
.- Table A.1 - Current currency & funds code list Table A.2 - Current funds code
- Table A.3 - List of codes for historic denominations of currencies & funds
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 different 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.
