How to read and use this map

County lines are administrative boundaries, not postal routes. A mailing address can use a city name associated with a neighboring area, and ZIP codes can cross county lines. When you need to identify a county for an address, confirm it with an official geocoder or local government source.

For classroom or planning use, print directly from this page. If labels become crowded, choose landscape orientation and reduce page margins. The underlying vector lines remain crisp at different sizes.
