Montana Address FAQ
RandAddress generates realistic-looking Montana addresses covering cities across the state. Each profile includes a street address, city, ZIP code, and a 406 phone number — 406 is Montana's only area code and has no overlay. Output clusters around the seven main population centers (Billings, Missoula, Bozeman, Great Falls, Butte, Helena, Kalispell), mirroring how Montana's roughly 1.1 million residents actually distribute across a state the size of Japan.
Almost everywhere. Montana has no statewide general sales tax at all. The narrow exception: roughly a dozen resort communities — notably Whitefish, West Yellowstone, Big Sky, Red Lodge, and Virginia City — are allowed by state law to levy a small local resort tax (capped at 3%) on tourist-facing purchases such as lodging, prepared food, and ski passes. Outside these resort zones, and for all non-tourist retail everywhere in the state, Montana is tax-free at checkout.
The cities, ZIPs, and 406 area code are authentic Montana data; street numbers and names are procedurally generated. Something worth flagging for Montana specifically: a meaningful share of real Montana addresses outside the main cities are rural routes or PO boxes rather than numbered streets. RandAddress produces urban-style street addresses that are statistically plausible for Billings, Missoula, Bozeman, or Great Falls, but will not correspond to real dwellings anywhere. Do not use for shipping, vehicle registration, or anything requiring address verification.
Montana occupies the entire 590–599 ZIP block. Billings (the state's largest city, in the east) uses 591xx (59101–59106). Missoula (west) uses 598xx (59801–59812). Bozeman (the Yellowstone gateway) is 597xx (59715–59718). Great Falls (north-central) sits in 594xx (59401–59406). Helena (the state capital) uses 596xx (59601–59626). Kalispell (Flathead Valley, near Glacier National Park) is 599xx (59901–59904). Butte, Havre, Miles City, and smaller towns fill the remaining 590/592/593/595 blocks. All ZIPs in this range that RandAddress emits are live USPS-delivery codes.
Montana's population clusters in a handful of cities and the generator samples them roughly in proportion. The big seven — Billings, Missoula, Great Falls, Bozeman, Butte, Helena, Kalispell — account for most output. Smaller towns from across the seven regions also show up: Havre and Glasgow in the north, Miles City and Sidney in the east, Anaconda and Livingston in the southwest, Belgrade and Laurel in the Gallatin / Yellowstone corridor, and Whitefish in the Flathead.
