Custom Color-Coded Maps
Use the mapBuilder form just above to create your own custom color coded map on Google Maps, color-coded by Counties or ZIP Codes
Quickly create a free live-linked interactive color coded map (also known as a choropleth map) on Google Maps based on Counties, 5-digit ZIP Codes or 3-digit ZIP Codes stored in a Google Sheets spreadsheet. Use any custom data column of your choice to assign different colors to each value, customize colors, add titles and more.
Data changed? No problem: the custom map you create is live-linked to the spreadsheet! So, change the spreadsheet, and the next time you visit the map, your updates will be automatically shown on the map!
No need to download complicated software. Use the easy mapBuilder form above to create custom county maps, highlight zip codes on a map, or any other choropleth thematic color code map using U.S. Counties or ZIP Codes.
Example Maps created using this Custom Color-Coded Maps tool (Counties on left, ZIP Codes in middle, and 3-digit ZIP Codes on right)

- In the “Search places” box above the map, type an address, city, etc. and choose the one you want from the auto-complete list

Explanation of Unitary Authorities, Council Areas, Principal Areas and Districts.

Other Notes
- The Search places box uses a standard Google Maps geocoding engine, therefore you can type street addresses, road names, points of interest, etc. to see what custom area that location is part of
- Many of the map layers from which this information is extracted are very large, so it may take several seconds for all of the map layers to finish drawing
- Because the map layers are large, boundaries will not be shown if you are zoomed out too far
- Note that typing an address will zoom in the map very close, whereas typing a city or county by itself will show you a map with a wider view
- Disclaimer: While the number of decimals in the latitude and longitude displayed for the map marker may imply a positional accuracy of within a few feet, note that Google Maps and the source data may not be that accurate. Accordingly, this tool should not be used for legal nor surveying purposes or anything beyond entertainment value.
