About Montana’s ZIP codes

Of Montana’s ZIPs, 317 are standard ZIP codes for street delivery, while 76 serve PO Boxes only and 11 belong to a single organization such as a university, a hospital, a large company or a government office. On the map 369 ZIPs have outlines; the other 35 are drawn as dots, because they cover no area of their own, and they have no residents counted in the Census.

The ZIPs are spread over 56 counties and 360 postal city names. Yellowstone County has the most, 22 (5.4% of the state’s), followed by Cascade County with 18 and Flathead County with 17. Wibaux County has the fewest, 1 ZIP.

The postal city with the most ZIP codes is Billings, with 14; it is also the most populous, with 143,646 people across its ZIPs. 7 of its postal cities are among the 2,000 most populous in the country, from Billings down to Butte.

The most populous is 59901 in Kalispell, with 57,900 residents, followed by 59102 in Billings with 48,133. Half of the 368 ZIPs with residents have more than 472 people and half fewer. 1 ZIP has 50,000 residents or more, while 238 have fewer than 1,000.

About these numbers

Population is the 2020 Census count for each ZIP Code Tabulation Area, the Census Bureau’s outline of the area a ZIP code delivers to. ZIP codes for PO Boxes and single organizations have no area of their own, so they count as zero. City names are postal city names (the name the Postal Service prefers on mail), not city limits, so a suburb with its own post office is counted as its own city.

Each ZIP is counted in the one county that holds most of its outline; ZIP codes do not follow county lines, so a few reach partly into a neighbor.

The map above opens with all 404 selected and framed. Click or tap a ZIP to drop it or add a neighbor, draw a circle or lasso to add more, then press Copy list or Download in the list panel to take the ZIP codes of Montana into a spreadsheet, an ad platform or a mailing tool.
