ZIP Codes in Oregon
Oregon's ZIP codes cover a state split sharply between the lush, rainy Willamette Valley in the west, home to the vast majority of its roughly 4.2 million residents, and a much drier, more sparsely populated high desert region east of the Cascade Mountains. Portland, by far the state's largest city, anchors the northern end of this population corridor, close to the Washington border.
How ZIP Codes Are Organized Across the State
Oregon's ZIP codes fall within the 97000–97999 range under the USPS system. Portland and the surrounding metro area occupy the lower end around 972xx, Salem, the state capital, sits near 973xx, and Eugene, home to the University of Oregon, carries codes closer to 974xx. Eastern Oregon, including Bend, pushes toward the upper end around 977xx.
Oregon's Major Metro Areas by Population
The chart below shows how heavily Oregon's population concentrates in the Willamette Valley corridor, with Portland far outpacing every other city in the state.
Portland's ZIP codes cover Oregon's largest city, well known for its strong environmental culture, craft beer and coffee scene, and lack of a state sales tax, which has long shaped its retail landscape. Eugene, further south along the Willamette River, carries a distinct college-town identity built around the University of Oregon. For a broader comparison, our full US ZIP code directory shows how Oregon's ranges fit alongside every other state.
Central and Eastern Oregon
East of the Cascade Mountains, Oregon's climate and landscape shift dramatically - Bend has grown into one of the fastest-growing small cities in the Pacific Northwest, driven by outdoor recreation access and relative affordability compared to Portland. Further east, Oregon's high desert region borders Idaho, and population density drops sharply, with ZIP codes here covering much larger geographic areas than those in the crowded Willamette Valley.
The Oregon Coast
Oregon's rugged Pacific coastline is entirely public by law, a distinctive feature that shapes the character of coastal towns and their ZIP codes, which see significant tourism traffic without the kind of exclusive private beach development found in many other coastal states. These communities blend fishing, tourism, and a slower pace of life quite different from Portland's urban energy.
Why ZIP Codes Matter Beyond Mail
In Oregon, ZIP codes carry particular weight for retail and tax planning, given the state's lack of a sales tax, which draws shoppers from neighboring Washington across the Columbia River. Portland's tech sector, sometimes called the "Silicon Forest," relies on ZIP-level data for site selection and talent recruitment. And Bend's rapid growth has made its ZIP codes a closely watched real estate market, similar to other fast-growing mountain towns across the West.
Border Regions and Neighboring States
Oregon shares borders with four states. To the north, the Columbia River separates Portland from Washington, though the two metro areas function closely together economically. To the south, California shares a similarly rugged coastline and forested interior. And to the east, Idaho's high desert continues Oregon's own eastern terrain.
