javascript - How can I get the country and region code using geolocation instead of full country and region names - Stack Overfl

I'm building a website that uses geolocation in HTML5 to provide a service specific to the region in which the user is. Here is what I have been doing: I use the Javascript in this SO question to get country and administrative region names. Then I search the country and region names in a database and it returns location-specific data that I can display.

Here is the script:

<script src=""></script>
<script>
    var region = "";
    var country = "";
    function getLocation()
    {
        if (navigator.geolocation)
          {
              navigator.geolocation.getCurrentPosition(showPosition,noGeolocation);
          } else {
              ...
          }
    }
    function showPosition(position)
    {
        var geocoder = new google.maps.Geocoder();
        var latlong = new google.maps.LatLng(position.coords.latitude,position.coords.longitude);
        geocoder.geocode({'latLng': latlong}, function(results, status) {
              if (status == google.maps.GeocoderStatus.OK) {
                  if (results[0]) {
                    for (var i = 0; i < results[0].address_ponents.length; i++)
                    {
                        var longname = results[0].address_ponents[i].long_name;
                        var type = results[0].address_ponents[i].types;
                        if (type.indexOf("administrative_area_level_1") != -1)
                        {
                            region = longname;
                        }
                        if (type.indexOf("country") != -1)
                        {
                            country = longname;
                        }
                      }
              }
        });
    }
    function noGeolocation()
    {
        ...
    }

    getLocation();
</script>

This script is working fine. I had no problem with it, until I used an OS and browser set to a different languages. The script then returned the country and region names in that language. Of course, I couldnt find any match in my database.

So, the question(s) is (are): is there a way to get language-independent country and region codes from google reverse geolocation? or is there a way to always get it in english? am I better off using IP geolocation then? or should I use a totally different method?

Thanks for the help.

You should use the short_name value for the country, which is the two-digit country code. These are ISO standard codes and should be the basis for your database lookup, not the localized country name.

Another options, which has ISO codes for administrative regions, is MaxMind's GeoIP2 JavaScript API:

http://dev.maxmind./geoip/geoip2/javascript/

It uses W3C geolocation when available and falls back on MaxMind's IP geolocation database otherwise. The free version requires attribution somewhere on your site.
