The International Code of Area Nomenclature (ICAN) provides a universal naming system or nomenclature for areas of endemism used in biogeography and elsewhere. The ICAN also serves as the international standard rules for proposing and using area names.
The ICAN was ratified by the Systematic and Evolutionary Biogeographical Association (SEBA) in Paris during July 2007.
