ZIP Codes in Mississippi
Mississippi's ZIP codes cover a state deeply shaped by the Mississippi River Delta in the northwest, a short but active Gulf Coast in the south, and Jackson, the capital, sitting roughly in the middle. With around 2.9 million residents, Mississippi remains one of the more rural states in the country, without a single dominant metro area the way many neighboring Southern states have.
How ZIP Codes Are Organized Across the State
Mississippi's ZIP codes fall within the 38600–39999 range under the USPS system. Jackson and the surrounding central Mississippi area occupy the middle of that range around 392xx, the Gulf Coast - including Gulfport and Biloxi - sits near 395xx, and the northern Delta region, along with Southaven near the Tennessee border, carries codes closer to 386xx–387xx.
Mississippi's Major Metro Areas by Population
The chart below shows how Mississippi's population spreads across its main metro areas, with Jackson leading but no single city dominating the state the way some neighboring states see.
Jackson's ZIP codes cover Mississippi's capital and largest city, a hub for state government and healthcare that has faced real infrastructure and economic challenges in recent years. The Gulf Coast metro area, spanning Gulfport and Biloxi, carries a very different character built around casino gaming, seafood, and tourism, rebuilt substantially in the years following Hurricane Katrina. For a broader comparison, our full US ZIP code directory shows how Mississippi's ranges fit alongside every other state.
The Mississippi Delta
The Delta region in the state's northwest is one of the most historically and culturally significant areas in the country, often called the birthplace of the blues, with cities like Clarksdale carrying deep musical heritage. Economically, the Delta remains heavily agricultural, built around cotton, soybeans, and catfish farming, and ZIP codes here rank among the lowest in the state for median income, a legacy of the region's complicated history.
The Gulf Coast
Mississippi's Gulf Coast, though shorter than neighboring Alabama or Louisiana's coastline, carries significant economic weight through casino gaming, seafood processing, and shipbuilding. ZIP codes along this stretch remain vulnerable to hurricanes, a factor that shapes both insurance costs and rebuilding patterns following major storms.
Why ZIP Codes Matter Beyond Mail
In Mississippi, ZIP codes carry particular significance for the agricultural and casino gaming industries - Delta farming cooperatives use ZIP-level data to coordinate cotton and catfish shipping logistics, while Gulf Coast casinos and hospitality businesses rely on ZIP codes to define tourism and service areas. Insurers along the coast use ZIP-level data extensively to assess hurricane risk, given the region's history of major storm damage.
Border Regions and Neighboring States
Mississippi shares borders with four states. To the north, Southaven sits just across the line from Tennessee, functioning almost as a Memphis suburb despite being in a different state. To the west, the Mississippi River separates the state from Arkansas and Louisiana. And to the east, the border with Alabama blends into a similar mix of Gulf Coast and rural farmland terrain.
