Custom map Google Maps: Create custom Google Maps, color-coded by Counties, ZIP Codes, or 3-digit ZIP Codes in a Google Sheet

Quickly create a free live-linked interactive color-coded map on Google Maps based on Counties, ZIP Codes, or 3-digit ZIP Codes stored in a spreadsheet. Use custom data fields to assign different colors to each value, customize colors, add titles and more. And the map is live-linked to the spreadsheet: change the spreadsheet, and the next time you visit the map, your updates will be automatically shown on the map!

Create your custom color-coded map using this form:

Map title
Google Sheet URL
1. Create or open a Google Sheet here
2. While viewing the Google Sheet, copy the entire Google Sheet URL shown in your browser’s address bar and paste it into the Google Sheet URL box above
3. The first 4 columns of your spreadsheet must be County, StateAbbrev, Data, and Color (all other columns will be ignored)
   – Column names do not matter, but they must be the first columns and must be in this order
   – The Data column is what gets color-coded; it can be anything (e.g. Name, Zone, Status, etc.)
   – The Color column can contain color names or hex values (e.g. red, #FF0000)
   Example showing a few rows of a County-based spreadsheet setup:

4. Your Google Sheet must be published using File > Publish to the web. Use the default values in that box and click Publish and OK.
   – DO NOT paste the link shown in the “Publish to the web” box into the “Google Sheet URL” box above. Instead, copy/paste the link as shown in Step 2.
   – DO NOT PUT CONFIDENTIAL INFORMATION IN THE GOOGLE SHEET; someone with the link could view it. This tool cannot edit your Sheet.

  • US coverage includes Counties in all 50 states plus Puerto Rico, US Virgin Islands, Guam, Northern Mariana Islands and American Samoa
    “Also show US city limits” draws all incorporated cities and towns in the United States and its territories and possessions
  • Within the UK, England displays Counties and Unitary Authorities, Scotland displays Council Areas, Wales displays Principal Areas, and Northern Ireland displays Districts. Explanation of Unitary Authorities, Council Areas, Principal Areas and Districts.
  • 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
  • Mexico displays Municipalities, which are the next level administrative divisions below State
  • Switzerland displays Districts

  • The Search places box uses a standard Google Maps geocoding engine, therefore you can type street addresses, road names, points of interest, and GPS coordinates (see * above) to see what county 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 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.
