title: Google Geocode API only USA results
body: <p>I'm using the simple URL that Google provides for zip code lookup.</p>
  
  <p><a href="http://maps.googleapis.com/maps/api/geocode/json?address=90210&amp;sensor=true" rel="nofollow">http://maps.googleapis.com/maps/api/geocode/json?address=90210&amp;sensor=true</a></p>
  
  <p>This URL will return results for the whole world but how do I limit those to just the USA? I looked it up but can't find anything. I'd hate to code more than necessary to make sure there are not any US addresses when there might be a way to add to the URL and get the:</p>
  
  <pre><code>  {
    "results" : [],
    "status" : "ZERO_RESULTS"
    }
  </code></pre>
  
  <p>This is what the API returns if there are no results at all. Much easier.</p>
