About Idaho’s ZIP codes

Of Idaho’s ZIPs, 250 are standard ZIP codes for street delivery, while 52 serve PO Boxes only and 15 belong to a single organization such as a university, a hospital, a large company or a government office. On the map 279 ZIPs have outlines; the other 38 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 44 counties and 264 postal city names. Ada County has the most, 33 (10% of the state’s), followed by Bonner County with 17 and Canyon County with 14. 4 counties have only 2 ZIPs each, the fewest.

The postal city with the most ZIP codes is Boise, with 27; it is also the most populous, with 266,760 people across its ZIPs. 13 of its postal cities are among the 2,000 most populous in the country, from Boise down to Eagle.

The most populous is 83646 in Meridian, with 69,818 residents, followed by 83301 in Twin Falls with 60,789. Half of the 278 ZIPs with residents have more than 1,256 people and half fewer. 6 ZIPs have 50,000 residents or more, while 121 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 317 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 Idaho into a spreadsheet, an ad platform or a mailing tool.
