Zip Code Map Instructions
To open the inter-active map Click on "Zip Code Map Instructions" at the Top of the Page.
Enter a USPS Zip code, the address (it can also be just a city and state, the state, a partial address or even a coordinate in the form of latitude, longitude) into the fields provided or click on the map to show the USPS Zip code as an overlay.
You can also click on the "Map Type" buttons (top right of the map) to show the zip code overlay and manually move and zoom the map. The "Zip Hybrid" Map Type shows the basic map with zip code boundaries overlaid. The "Zips" Map Type shows just the zip code boundaries without the underlying Google map layer.
