About Wyoming’s ZIP codes

Of Wyoming’s ZIPs, 141 are standard ZIP codes for street delivery, while 50 serve PO Boxes only and 3 belong to a single organization such as a university, a hospital, a large company or a government office. On the map 179 ZIPs have outlines; the other 15 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 23 counties and 176 postal city names. Laramie County has the most, 16 (8.2% of the state’s), followed by Lincoln County with 16 and Natrona County with 15. 2 counties have only 2 ZIPs each, the fewest.

The postal city with the most ZIP codes is Cheyenne, with 7; it is also the most populous, with 94,477 people across its ZIPs. 4 of its postal cities are among the 2,000 most populous in the country, from Cheyenne down to Laramie.

The most populous is 82001 in Cheyenne, with 37,528 residents, followed by 82009 in Cheyenne with 35,700. Half of the 179 ZIPs with residents have more than 490 people and half fewer. 119 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 194 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 Wyoming into a spreadsheet, an ad platform or a mailing tool.
