Pursuant to the principles of good practice governing the naming of entities within the OpenStreetMap project, the general rule provides that the name in common and official use by the local population at the relevant location shall be applied on the map (see: https://wiki.openstreetmap.org/wiki/Names#Good_practice)

In accordance with this principle, it is an undisputed fact that all competent institutions, as well as the vast majority of inhabitants of this federal unit within the Federation of Bosnia and Herzegovina, use the designation “Hercegbosanska županija.” This nomenclature is consistently applied by official and legally constituted bodies, including the Government of the Canton, the Cantonal Assembly, and other organs of public administration and civil services (see: https://www.vladahbz.com/ ; https://www.skupstinahbz.com/show_page/11/o-zupaniji ; https://gss-hbz.com/ ).

Furthermore, and of decisive importance, the Constitution of the Canton explicitly and formally establishes “Hercegbosanska županija” as the official constitutional name of the canton (see: https://www.paragraf.ba/propisi/hercegbosanska-zupanija/ustav-hercegbosanske-zupanije.html ). Accordingly, any alternative designation would be inconsistent with the constitutional order and contrary to the prevailing legal and factual practice within the territory of the Canton.
