Montana Zip Codes by Population

Below are 367 Montana zip codes sorted by population from largest to smallest. The population data are from the 2021 American Community Survey. You can copy and paste this list directly into your favorite spreadsheet program. Don't you just adore lovely numbers listed nicely in columns & rows? We do!

Some of these zips may be mostly within a neighboring state and only slightly within Montana. We follow the US Census Bureau's lead here and if any portion of the zip code intersects Montana (no matter how small), we include that zip code both in the Montana list below as well as in the neighboring state's list of zip codes.
