About Colorado’s ZIP codes

Of Colorado’s ZIPs, 443 are standard ZIP codes for street delivery, while 157 serve PO Boxes only and 41 belong to a single organization such as a university, a hospital, a large company or a government office. On the map 527 ZIPs have outlines; the other 114 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 64 counties and 399 postal city names. El Paso County has the most, 63 (9.8% of the state’s), followed by Denver County with 48 and Weld County with 40. 3 counties have only 1 ZIP each, the fewest.

The postal city with the most ZIP codes is Denver, with 63; it is also the most populous, with 1.1 million people across its ZIPs. 27 of its postal cities are among the 2,000 most populous in the country, from Denver down to Peyton.

The most populous is 80134 in Parker, with 76,369 residents, followed by 80013 in Aurora with 75,099. Half of the 521 ZIPs with residents have more than 2,704 people and half fewer. 13 ZIPs have 50,000 residents or more, while 184 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 641 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 Colorado into a spreadsheet, an ad platform or a mailing tool.
