Montana ZIP Code Map with Counties
All 56 of Montana’s counties appear on this map, with ZIP boundaries layered over them across Big Sky Country, from Yellowstone County around Billings to Flathead County in the northwest. Counties carry clean color separation, so a ZIP and its county read together at a glance.
This version is built for territory work rather than route reference, supporting sales regions, service coverage, and franchise planning assigned by county and ZIP.
