As in V1 and HoI3, the naming convention in V2, which we used in the development of the Clio map project upon which the V2 map is based, is to use city names for the name of the provinces (the smallest geopolitical units on the map). The exception to this rule was pure island provinces, for which we chose to use the name of the island or archipelago.
This is how it was in V1, and in the Hearts of Iron series, and this is how it is in V2.
Now, region names (for the geopolitical unit represented by 4 or 5 provinces) were developed by Paradox and in some cases represent historical regions/states, in other cases (particularly outside Europe and the Americas) they currently take their name after one of the provinces.
Both province names and region names are easily moddable if you want them to display something different in your own personal game. Simply open up the file localisation/text.csv with notepad, and towards the bottom you will find first the list of all the provinces with their names assigned, then the list of regions with names assigned. Find your particular province or region, change the name to whatever you want, save, restart and you should have the new name depicted. Easy as pie.
