Google-maps – Zip codes in Radius Google Map

google mapsmapmappingzipcode

Hope someone can advise,

I would like to be able to use google map API to find all Zip codes/cities with x Miles of a point.

Has anyone done such a thing with google map or maybe some other type of service.

Would love to know if so how you have achieved it !

Thank you if you can advise.

There's nothing in the Google Maps API that can help with that, and I've never heard of any such service that could be mashed up with a Google Map.

What you could do is obtain a list of the locations of all the zip codes. Do a web search for [free zip code database] there are lots of them out there. Put it on your server then write your own server script to search it.

One option is to use the geonames web service that returns locations from zip codes. Here's a quick example of how to use that web service with dojo.

            dojo.require("dojo.io.script");
                function getPlace() {
        var zip = dojo.byId('zipcode').value;
        console.log('zip is ', zip);
        //use country code to get results for a specific country
        //var gn_url = 'http://ws.geonames.org/postalCodeLookupJSON?postalcode=' + zip + '&country=US';
        var gn_url = 'http://ws.geonames.org/postalCodeLookupJSON?postalcode=' + zip;
        console.log(gn_url);
        dojo.io.script.get({
          url: gn_url, 
          callbackParamName: "callback",
          load:function(response, io) { 
            console.log('got json.'); 
            console.dir(response); 
            places = response.postalcodes; 
            var infos = []
            dojo.forEach(places, function(p, i) {
                infos[i] = p.placeName + ', ' + p.adminName1 + ', Lat: ' + p.lat + '; Long: ' + p.lng + '<br />';
            });
                dojo.byId('postalCode').innerHTML = infos.join('');
          }, 
          error:errorCb
        });   
        }

        function errorCb(type, data, evt){
                debug(data);
        }
         </script>
     </head>
     <body class="tundra">
    Enter a zip code: <input id="zipcode" type="text" /> <button onclick="getPlace(); return false;" value="Find Place.">Find Place.</button>
      <div>Places:</div><div id="postalCode"></div>
    </body>
</html>
