RE: us zip code border
Hi,
The boundary data you are looking for is not available through MWS. You'd
have to purchase some third party polygon data containing zip boundaries,
upload it as a polygon datasource, then display it through your app. You
might want to check out a Virtual Earth solution to this at:
