A recent work proposed a new naming system for biogeographical areas: the International Code of Area Nomenclature (ICAN). This system aims to standardize area names used in biogeography and constitutes a key step towards maturity of this discipline. We point out a number of issues in this first version of ICAN. These include the lack of distinction between classification and nomenclature, the use of ranks, the criteria of area definition, the conflation of diagnosis and description, the ambiguous use of valid/available, and the system of amendments. We suggest postponing the initial date of application of this code until consistent rules are provided.
