About Wisconsin ZIP codes

Wisconsin is home to 732 ZIP codes ranging from 53001 in the south to 54986 in the north, covering 72 counties and 627 communities across one of the Midwest's most geographically diverse states. From the urban neighborhoods of Milwaukee and Madison to the quiet lake towns of the Northwoods, Wisconsin's postal system is organized into 18 distinct ZIP prefixes that reflect the state's regional layout. Dane County stands out as the ZIP code leader with 46 codes, a testament to Madison's continued growth as a major hub for government, education, and commerce. Whether you're mailing a package to Green Bay or looking up a rural route in Vilas County, Wisconsin's well-structured ZIP code system makes navigating the Badger State straightforward.

Wisconsin ZIP codes span two major prefix groups: the 530–539 range covers the southern and central portions of the state, including Milwaukee and Madison, while the 540–549 range serves the northern and western regions, encompassing areas like Green Bay, Eau Claire, and the Upper Peninsula border communities. This geographic split reflects how the U.S. Postal Service divided the state into distinct sectional center facilities to efficiently route mail across Wisconsin's varied terrain, from its urban corridors to its rural northwoods.

Dane County leads Wisconsin with 46 ZIP codes, reflecting the dense population and sprawling suburban growth surrounding Madison, the state capital and home to the University of Wisconsin.

Quick facts

Wisconsin's ZIP code range begins at 53001 and extends all the way to 54986, spanning nearly 2,000 possible numeric values across 18 active prefixes — one of the broader allocations among Midwestern states.
Milwaukee County, despite being the most densely populated county in Wisconsin, ranks second in ZIP code count with 42, behind Dane County's 46 — a reflection of Madison's rapid suburban expansion in recent decades.
Wisconsin notably skips several prefix blocks entirely, such as 533 and 536, which were never assigned to the state, leaving gaps in its numeric sequence that hint at early postal planning decisions made when ZIP codes were introduced in 1963.
