ISO 4217

ISO 4217 is a standard published by the International Organization for Standardization (ISO) that defines alpha codes and numeric codes for the representation of currencies and provides information about the relationships between individual currencies and their minor units.

The tables, history and ongoing discussion are maintained by SIX Group on behalf of ISO and the Swiss Association for Standardization.

In 1973, the ISO Technical Committee 68 decided to develop codes for the representation of currencies and funds for use in any application of trade, commerce or banking.

This eliminates the problem caused by the names dollar, franc, peso, and pound being used in dozens of countries, each having significantly differing values.

The following is a list of active codes of official ISO 4217 currency names as of 1 January 2024[update].

When this occurs, it is necessary to know the decimal relationship that exists between the currency concerned and its minor unit.

These show the number "0", as with currencies whose minor units are unused due to negligible value.

[citation needed] The ISO standard does not regulate either the spacing, prefixing or suffixing in usage of currency codes.

The style guide of the European Union's Publication Office declares that, for texts issued by or through the Commission in English, Irish, Latvian, and Maltese, the ISO 4217 code is to be followed by a "hard space" (non-breaking space) and the amount:[45] and for texts in Bulgarian, Croatian, Czech, Danish, Dutch, Estonian, Finnish, French, German, Greek, Hungarian, Italian, Lithuanian, Polish, Portuguese, Romanian, Slovak, Slovene, Spanish, and Swedish the order is reversed; the amount is followed by a non-breaking space and the ISO 4217 code: As illustrated, the order is determined not by the currency but by the native language of the document context.
