ZIP codes are a system of postal codes used by the United States Postal Service. ZeeMaps supports Zip Code Lookup, using the View -> Zip Code Lookup menu item on your map.
Zip Code Lookup for Texas
For example, suppose you want to lookup all Zip codes for the state of Texas. Highlight the state of Texas, using the Additions -> Highlight Regions -> States on your map.
Then, once the state of Texas has been highlighted, select the menu item View -> Zip Code Lookup, and click an the highlighted Texas region. You’ll get a list of all Zip Codes in Texas.
The same feature can be used to lookup Zip Codes of a particular city, county, or an arbitrary building. You can click on a building to get the Zip Code of the building instead of the area. You are not limited to using pre-defined regions for doing a zip code lookup. Since ZeeMaps allows you to define arbitrary areas like circles, rectangles, polygons and hand-drawn, you can lookup zip codes for any region on the map.
Unlike the US Postal Service’s Zip Code Lookup service, with ZeeMaps you can easily lookup zip codes for an entire region, instead of having to do it one zip code at a time.
When you click on an highlighted region, the lookup is done for the entire region. If you want to find the zip code for a point within an highlighted region, first click outside the region and then move the zip code locator to the point inside the highlighted region.
