ZIP Codes in Kansas
Kansas's ZIP codes cover a state split fairly cleanly between the Kansas City metro suburbs in the northeast, a scattering of mid-size cities across the central plains, and vast, sparsely populated farmland stretching west toward Colorado. With around 2.9 million residents, Kansas's population is concentrated far more heavily near its eastern border than in the wide-open western two-thirds of the state.
How ZIP Codes Are Organized Across the State
Kansas's ZIP codes fall within the 66000–67999 range under the USPS system. The Kansas City metro suburbs, including Overland Park and Kansas City, Kansas, occupy the lower end around 660xx–662xx. Topeka, the state capital, sits near 666xx, and Wichita, the state's largest city, carries codes closer to 672xx, with the sparsely populated western plains stretching out toward 677xx.
Kansas's Major Metro Areas by Population
The chart below shows how population splits between the Kansas City suburbs and Wichita, the state's two clear population centers, with everything else considerably smaller.
The Kansas side of the Kansas City metro area - including Overland Park, one of the fastest-growing suburbs in the entire Midwest - carries ZIP codes with a notably different economic profile from Wichita, further south, which has built its economy heavily around aviation manufacturing, home to major aircraft makers for decades. Topeka, the state capital, and Lawrence, home to the University of Kansas, round out the northeastern part of the state's population centers. For a broader comparison, our full US ZIP code directory shows how Kansas's ranges fit alongside every other state.
The Kansas City Metro Split
Kansas City is unusual in that it straddles two states, with a Kansas side and a much larger Missouri side sharing the same metro economy. ZIP codes on the Kansas side, including Overland Park, Olathe, and Kansas City, Kansas itself, sit right along the border with Missouri, and many residents cross the state line daily for work without a second thought, despite the different state tax and regulatory environments on each side.
Western Kansas and the High Plains
West of Wichita and Topeka, Kansas transitions into the high plains, an area of vast wheat fields and cattle ranching with population density dropping sharply the further west you travel. This region borders Colorado, and the landscape shifts gradually from flat farmland into the beginning of higher elevation terrain as it approaches the Rocky Mountains further west. ZIP codes here often cover enormous geographic areas for relatively small populations, a pattern common across the Great Plains.
Why ZIP Codes Matter Beyond Mail
In Kansas, ZIP codes carry particular significance in the agricultural commodity trade, given the state's position as one of the country's largest wheat producers - grain elevators and cooperatives rely on ZIP-level data to coordinate shipping across the state's rail network. The aviation industry around Wichita also uses ZIP-level data for supply chain and workforce planning, given the concentration of aerospace manufacturing in that specific metro area.
Border Regions and Neighboring States
Kansas shares borders with four states. To the east, Missouri connects into the shared Kansas City metro economy. To the north, Nebraska blends into similar high-plains farmland. And to the south, the border with Oklahoma continues the same wheat-and-cattle landscape found throughout central Kansas.
