Looking for historical county boundaries on Google Maps? Here it is: Historical U.S. County Boundary Maps.

- US coverage includes Counties in all 50 states plus Puerto Rico, US Virgin Islands, Guam, Northern Mariana Islands and American Samoa.
- Within the UK, England displays Counties and Unitary Authorities, Scotland displays Council Areas, Wales displays Principal Areas, and Northern Ireland displays Districts. Described here.
- Australia displays Local Government Areas (LGAs).
- New Zealand displays Territorial Authorities.
- Canada displays Census Divisions, which are Counties in some provinces but may include other geographies shown here.
- Mexico displays Municipalities, which are the next level administrative divisions below State.
- Switzerland displays Districts.

- The Place box uses a standard Google Maps geocoding engine, therefore you can type street addresses, road names, points of interest, and the like, to see what county that address or road is located in.
- The "Use current location" button will be more accurate on smartphones and other devices containing a GPS; desktop browsers typically show an approximate location.
- Disclaimer: While the number of decimals in the latitude and longitude displayed for the map marker imply a positional accuracy of within a few feet, note that Google Maps is not inherently that accurate, and therefore this tool should not be used for legal purposes or anything beyond entertainment value.
- Occasionally, county lines may take up to 10 seconds to appear; if the county lines never appear, try refreshing the page (F5) and try your search again. Some very complex shapes (e.g. long boundaries along jagged coastlines) may not draw.
- This tool uses an experimental Google Maps API feature called Fusion Table Layers. The underlying county boundary map files used are quite large, and Google Fusion Tables are themselves a beta product. Zooming out too far will cause strange results. As with any new and innovative technology, don't be surprised if things occasionally don't function as expected.
- County lines must be viewed one country at a time.
