About Montana ZIP codes
Montana is served by 293 ZIP codes that cover all 56 counties and 269 cities across the fourth-largest state in the U.S. by area. Ranging from 59001 to 59937, these ZIP codes blanket everything from the vast eastern prairies and agricultural heartland to the rugged Rocky Mountain corridors of the west. Yellowstone County, home to Billings, leads the state with 20 ZIP codes, while many of Montana's rural ZIP codes each encompass hundreds of square miles of wide-open terrain. Whether you're looking up a ZIP code for a small ranching community on the high plains or a mountain town near Glacier National Park, all Montana ZIP codes share the unmistakable 59 prefix.
All Montana ZIP codes begin with the prefix 59, spanning from 590 through 599. These prefixes generally correspond to geographic regions within the state, with lower numbers like 590 and 591 covering the south-central and eastern portions of Montana, while higher prefixes such as 598 and 599 serve the northwestern areas including Kalispell and the Flathead Valley.
Yellowstone County has the most ZIP codes in Montana with 20, which reflects its status as the state's most populous county and home to Billings, Montana's largest city, requiring multiple postal zones to serve its sprawling urban and suburban communities.
