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.
No need to download complicated software. Use the easy mapBuilder form above to create a custom county map, custom zip code map, custom delivery zones map, custom sales map, custom US map or any other choropleth thematic color code map using U.S. Counties or ZIP Codes.
More is more: Include additional columns in your spreadsheet! Additional columns will be viewable using the “more…” button that appears when you click your custom areas. Any links (urls) you include in your spreadsheet will become clickable links!
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!

Additional Usage Tips
- Be sure to read the Quick Tips above on how to use this map tool
- 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
– 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 - Because the map layers are complex, boundaries will not be shown if you are zoomed out too far
