Custom Territories using ZIP Codes on Google Maps tool

Create your own custom Google Map using any combination of ZIP Codes, counties, cities and more

Quickly create custom sales territory maps, delivery area maps, service area maps or other custom territory maps on Google Maps. This custom Google Maps tool enables you to create custom territory maps showing an overall merged boundary and add your own title to the map. Popular uses include custom sales maps, custom delivery area maps, custom territory maps, business planning and publishing.

How to create a sales territory, delivery area, or service area map based on ZIP Codes

Follow the easy steps below to create a custom map using ZIP Codes, optionally show the overall boundary and add a map title

To zoom to one or multiple ZIP Codes, and optionally show their boundary (e.g. for a service territory, sales territory or delivery area), create a link such as this:,10024,10025,10026&zipboundary=show&title=My+Service+Territory

TIP: copy/paste the link above and customize to suit your needs

NEED TO DETERMINE WHICH ZIP CODES YOU SERVE? Type your business address in the "Search places" box above the map, check the "Show ZIP Code boundaries" (and optionally labels) box in the lower left, then use the "Drawing Tools" button on the left side of the map to draw a polygon around the area you would like to deliver to. A list of ZIP Codes will appear in a box from which you can copy/paste to build your link!

The parameters you can use to build your custom link are:

  • zips - expects a comma-separated list of one or multiple 5-digit U.S. ZIP Code(s) (do not use spaces between the commas), for example: ?zips=10023,10024
  • zipboundary - optionally shows a merged overall boundary based on the zips (e.g. for a service territory or delivery area) by using the word show, as in: &zipboundary=show
  • cities - optionally shows U.S. city limits by using the word show, as in: &cities=show
  • title - optionally give your map a title (use the + character to represent spaces), for example: &title=My+Sales+Territory
  • color - optionally choose the color used for the Map Title and the ZIP boundary, expects a 6-character hex color code without the leading # character, for example, &color=00FF00 would create a green map title and ZIP boundary (free tools are widely available on the internet to find your hex color)
  • labels - optionally shows ZIP Code labels by using the word show, as in: &labels=show

A few important things to make this work:

  1. You must use the question mark ( ? ) right after .html, as shown above and below
  2. Do NOT use spaces anywhere in the URL or query parameters
  3. You must separate query parameters using the ampersand ( & ), as shown above and below
  4. User the + character to represent spaces in the title parameter

TIP: For simplicity, you can drop the https://www from the front and just create the link as:

With this functionality, you can feel free to create links on your own website that open a window to the Custom Maps on Google Maps tool, zoomed into your area of interest and showing a ZIP Code based sales territory, service territory or delivery area!

Some websites that make use of this custom map functionality

Feel free to share this with others who may find this functionality useful!

  1. Follow the instructions above this box to create a link to your own custom map.
  2. Once your customer uses this map, they can then zoom in, search for their address and so on. To go to another location, type any place or address in the "Search places" box above the map*
    OR: Zoom into your place of interest on the map
  3. Optionally, check the "Show ZIP Code boundaries" and "Show ZIP Code labels" checkboxes in the lower left corner of the map to see the ZIP Codes on the map
  4. Optionally, check the "Also show US city limits" checkbox in the lower left corner of the map to see City Limits overlaid on the map (available in the U.S. only)
  5. Click the "⊕ Locate" button in the upper right corner of the map to use your current location † and quickly answer "what county am I in?"
  6. Subscribe in the top header to receive notification of tool updates and usage tips

You can also type in GPS coordinates in decimal degrees into the Search places box. For example, type -105.25, 40 for Boulder, Colorado.
**  or equivalent province, district, etc.
*** All information is reported based on the location of the blue dot on the map; to move the blue dot, click the map
†  The "Locate" button will be more accurate on smartphones and other devices containing a GPS; desktop browsers typically show an approximate location

  • 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.
