This is a Census ZIP Code Tabulation Area (ZCTA), built from 2020 Census blocks. It is not a USPS delivery route, and a ZIP that is only PO boxes or one large building has no area. Source: U.S. Census Bureau, 2020 ZIP Code Tabulation Areas.
Questions
How many ZIP codes are in Montana?
369 Census ZIP code areas have most of their area in Montana, and 4 more from neighbouring states reach across the state line. A ZIP code that is only PO boxes or one large building has no area, so it is not counted here.
Are these the same as the ZIP codes the post office uses?
Close, but not exactly. These are the Census Bureau's ZIP Code Tabulation Areas (2020), built from census blocks so that each area matches the ZIP code most of its addresses use. A ZIP code is really a set of mail delivery routes, so its edges can differ a little.
How do I find the ZIP code of an address or a point?
Open the ZIP code map, then click the spot or type a ZIP code. It shows the ZIP code area, its county and state, and its land area. It is free and needs no account.
Can I add ZIP codes to a list of addresses or coordinates?
Yes. Upload a CSV with latitude and longitude columns and every row gets zip, zip_state and zip_county. It is part of every paid plan.
