Iowa is served by 851 ZIP codes that span from 50002 in the west to 52807 along the Mississippi River in the east, covering all 99 of the state's counties and 765 distinct cities and communities. The state's ZIP codes use prefixes ranging from 500 to 528, with central and western regions using the lower numbers and eastern Iowa communities assigned higher prefixes. Polk County, home to the capital city of Des Moines, accounts for the largest share with 59 ZIP codes, reflecting the concentration of population and suburban growth in the metro area. Whether you're looking up a rural farming community on the western plains or a bustling city along the eastern river corridor, Iowa's ZIP code system provides comprehensive coverage of the Hawkeye State.
Iowa ZIP codes begin with the digits 50 through 52, reflecting the state's assignment within the national postal system. Prefixes in the 500–516 range generally cover central and western Iowa, including the Des Moines metropolitan area, while prefixes in the 520–528 range serve eastern Iowa, encompassing cities like Cedar Rapids, Davenport, and Dubuque. This geographic split roughly follows Iowa's population distribution along its major interstate corridors.
Polk County leads Iowa with 59 ZIP codes, which is no surprise given that it is home to Des Moines, the state capital and largest city, along with a sprawling network of suburbs and smaller communities that each require their own postal designations.
Quick facts
Iowa's ZIP code system spans 99 counties — the most counties of any U.S. state that uses only a two-digit prefix range, making its postal geography remarkably dense.
The lowest Iowa ZIP code, 50002 (Adair), and the highest, 52807 (Davenport), are separated by roughly 250 miles, stretching from the western prairies to the Mississippi River bluffs on the eastern border.
When the ZIP code system was introduced in 1963, Iowa was one of the first states to see rapid adoption because its extensive network of small rural post offices made standardized codes essential for efficient mail sorting.
