title: Google Maps API/Geocoding - Can I retrieve a response by just passing a ZIP code?
body: <p>Greetings:</p>
  
  <p>I have put together a RESTful web service in .NET 3.5 that takes a phone number and does a reverse lookup to retrieve the ZIP code of that location. I am now creating an *.aspx page that will present the output of a request to the Google Maps API. This output will be a polygon on a map that will be that US ZIP code. I'm wondering if I could just pass in only that ZIP code in the http request for the address parameter. The example at <a href="http://code.google.com/apis/maps/documentation/geocoding/" rel="nofollow noreferrer">http://code.google.com/apis/maps/documentation/geocoding/</a> basically passes in the entire street address. Not quite sure if the ZIP would be sufficient. </p>
  
  <p>Anyone had experience working with this? </p>
  
  <p>Thanks in advance!</p>
