How to Read a Denver ZIP Code Map

Denver's ZIP code system can seem confusing at first glance, with 44 codes spanning from 80202 to 80294. But there's a logical pattern to the numbering and geography that makes the system easier to navigate once you understand the basics.

All Denver-area ZIP codes begin with '802' — part of the USPS Sectional Center Facility (SCF) designation for the Denver postal district. The last two digits generally follow a geographic pattern: lower numbers (80202–80210) cluster around central and south Denver, while higher numbers (80229–80249) tend to cover northern and eastern suburbs. PO Box-only ZIP codes (80217, 80264, 80290, 80293, 80294) don't correspond to residential areas and are used exclusively for post office box mail.

Denver's ZIP code boundaries don't always align neatly with neighborhood boundaries, city limits, or county lines. For example, ZIP code 80227 straddles Denver and Jefferson County, while 80214 covers the separate city of Edgewater. This means that two homes on the same street could be in different ZIP codes, counties, or even cities. When researching school districts, property taxes, or city services, always verify the specific address rather than relying on ZIP code alone.

The Denver metro area spans eight counties: Denver, Adams, Arapahoe, Jefferson, Douglas, Broomfield, Elbert, and Clear Creek. ZIP codes in Adams County (like 80221, 80229, 80233, 80234, 80241) tend to have lower property taxes and more affordable housing. Jefferson County ZIP codes (80214, 80215, 80226, 80227, 80228, 80232, 80235) offer mountain proximity. Arapahoe County codes (80231, 80246, 80247) are convenient to the Denver Tech Center employment hub.
