This Montana address generator creates a real-looking but fictional Montana address with a valid MT ZIP code. The city is set to Billings and the ZIP is a real code issued in Montana, so the address is internally consistent with Montana (MT) even though the street name and house number are invented and belong to no real residence.
It is ideal for testing shipping forms, address validation and region-specific features that need a believable Montana address, or for keeping your real address private when a site only needs a plausible one. The phone, name and other fields round out a full, fictional US profile.
Real Montana ZIP codes run from 59001–59937, and common MT area codes include 406. When you need a random Montana address whose fields agree with each other, this generator pins the 591xx Billings range — the reference table below lists real example ZIPs to compare against.
Montana is one of only five states with no statewide sales tax, which makes an address here useful for a specific testing job: proving the zero-rate branch of a tax calculation actually works. Montana has no statewide sales tax, but state law allows designated resort communities and resort areas — places such as Whitefish, Big Sky and West Yellowstone — to levy a local resort tax. So the state rate is zero while a specific address inside one of those communities is not. The best case for testing that your tax lookup keys on the full address rather than the state alone. Two Montana addresses can legitimately return different totals, which catches any code that resolves tax by state code only.
All data is fictional. The address points to no real occupant, the ID field is a masked test placeholder, and card numbers are sandbox values valid in format only — keep generated data to testing and privacy, never fraud.
No statewide sales tax, and a three per cent one in the ski towns.
Montana is the state that proves a zero state rate is not a zero total. It levies no statewide sales tax, and it also lets small tourist towns levy their own: under state law the Department of Commerce can designate an incorporated town of fewer than 5,500 people a resort community, or an unincorporated area of fewer than 2,500 a resort area, and those places may charge a local resort tax set locally and capped at three per cent.
That makes a Montana address the most useful fixture in the no-sales-tax family, and the opposite of New Hampshire's. New Hampshire, Oregon and Delaware have no local option at all, so a correct calculation there returns zero from every layer. Montana returns zero from the state layer and possibly three per cent from the municipal one — which is precisely the branch that code resolving tax from a state code alone gets wrong, and gets wrong silently, because zero is a plausible answer.
Postally the state is wide and thin: 404 codes across ten prefixes and 56 counties, about 7.2 codes per county — one of the lowest ratios in the country, and a consequence of a large area with few people in it. The ten prefixes run 590 through 599 without a gap, so Montana is one of the 25 states a validator can express as a single range.
The prefix sizes are worth a glance before you assume they track population. The largest by code count is 590, whose principal place in the postal file is Ashland — a community of a few hundred people — ahead of 594 around Great Falls and 598 around Missoula. A sorting facility's code count follows the territory it covers, and in Montana the territory is the story.
