ZIP Codes in Arkansas
Arkansas's ZIP codes cover a state shaped by the Ozark and Ouachita Mountains in the north and west, the flat, fertile Mississippi Delta in the east, and a capital region around Little Rock that anchors the state's economy and population. With around 3 million residents spread across 75 counties, Arkansas has a more evenly distributed population than many of its neighbors, without a single metro area dominating the way Phoenix or Atlanta do in nearby states.
How ZIP Codes Are Organized Across the State
Arkansas's ZIP codes fall within the 71600–72999 range under the USPS numbering system. Little Rock and the surrounding central Arkansas region sit around 722xx, while Fort Smith, near the Oklahoma border, carries codes closer to 729xx. Northwest Arkansas - home to Fayetteville, Bentonville, and the rapidly growing area around Walmart's corporate headquarters - occupies the low 727xx range, one of the fastest-growing ZIP code clusters in the state over the past two decades.
Arkansas's Major Metro Areas by Population
The chart below shows how Arkansas's population splits across its main metro areas - notably more balanced than states with one dominant city, with Northwest Arkansas closing in on the Little Rock metro.
Little Rock's ZIP codes cover Arkansas's capital and largest city, home to state government, healthcare, and a diversified regional economy. Northwest Arkansas, by contrast, has transformed dramatically in recent decades, its ZIP codes now covering a corporate corridor built around Walmart, Tyson Foods, and J.B. Hunt, with Fayetteville, Bentonville, Rogers, and Springdale forming one of the fastest-growing metro areas in the country.

The Arkansas Delta and Eastern Arkansas
Eastern Arkansas, part of the broader Mississippi Delta region, is covered by ZIP codes with some of the lowest population density and median income in the state, reflecting a heavily agricultural economy built around rice, soybeans, and cotton. This flat, fertile land sits along the border with Mississippi and Tennessee, and shares a similar Delta character with ZIP codes on both sides of the Mississippi River.
The Ozarks and Northern Arkansas
Northern Arkansas is dominated by the Ozark Mountains, a region of small towns, lakes, and forested hills that draws significant tourism, particularly around Branson-adjacent areas near the Missouri border. ZIP codes here tend to cover larger geographic areas relative to their population, similar to rural mountain regions elsewhere in the country, and many residents commute longer distances between small towns than their counterparts in the more urbanized central and northwest parts of the state.
Why ZIP Codes Matter Beyond Mail
In Arkansas, ZIP codes serve purposes well beyond simple mail routing. Real estate listings in the fast-growing Northwest Arkansas corridor rely on them heavily to signal proximity to major employers and school districts. Agricultural businesses in the Delta use them to coordinate logistics for crop transport. And healthcare providers across the state's more rural counties use ZIP-level data to plan service coverage in areas where the nearest hospital can be a significant drive away.
Border Regions and Neighboring States
Arkansas shares borders with six states, more than almost any other state in the country. To the northwest, the border with Missouri runs through Ozark terrain that looks similar on both sides. To the west, Fort Smith sits right across the line from Oklahoma, with a shared metro economy spanning both states. And to the south, rural ZIP codes near Louisiana reflect a similar Delta and pine-forest landscape that continues across the border.
