Wisconsin Zip Code Map
Postal zones sit right on top of the road network, so mail routes line up against real streets instead of floating on a blank outline.
Base layer covers:
- County boundaries
- Major road network
- State and national parks and conservation areas
At 1:580,000 scale, the map fits the whole state on one sheet. Useful for delivery planning, sales coverage, or general reference where the roads matter as much as the mail zones.
