One way or another you're going to need to get Zip code polygons or Zip Cod Centroids somewhere. Then you can present your data with any one of several tools, such as GE-Graph.

You can get Zip code SHP files here. But will be difficult to do the entire US since files are too large for Google Earth to handle.

Zip Code Centroids, you can get here.

Just assign lat/lon to each zip code in your spreadsheet, and I think GE-Graph can do the rest.

I was able to get the Centroids file to work...thank you!

We can use that but me ideal objective is to create a map like in examples "C" and "D" in this link:

I only want to do the zip codes for one state not the whole country. I am not sure what to do with the SHP files. From what I can see, I need to pull them into Google Earth not GE-Graph but they are not in the correct format to do that. Any suggestions?

Thanks!
