I came across this when I did a search on SO: http://stackoverflow.com/questions/518026/zip-code-to-city-state-and-vice-versa-in-a-database
But I'm wondering, why can't we just use the Maps APIs for this? Has anyone tried doing this?

A:
It's pretty easy to use the Geonames webservice apis for this, specifically the postalCodeSearch method. Works great in my experience unless you're issuing multiple queries/second, although caching results is generally worthwhile. (ie: they do not change frequently.)

Yes, it's pretty easy to do it with Google Maps Geocoding getLocations().

<script src="http://maps.google.com/maps?file=api&v=2" type="text/javascript"></script>
<script type="text/javascript">
var geocoder;
var map;
var address = "10001"; //NEW YORK zip
function load()
{
map = new GMap2(document.getElementById("map"));
geocoder = new GClientGeocoder();
geocoder.getLocations(address, addToMap);
}
function addToMap(response)
{
place = response.Placemark[0];
point = new GLatLng(place.Point.coordinates[1],place.Point.coordinates[0]);
map.setCenter(point, 13);
marker = new GMarker(point);
map.addOverlay(marker);
marker.openInfoWindowHtml(place.address);
}
</script>
</head>
<body onload="load()" onunload="GUnload()">
<div id="map" style="width: 500px; height: 500px"></div>
</body>
</html>
You could give it a try online on Google code playground.
Have fun!
