Geocoding Component Restrictions

This example creates a request to the geocoding service that restricts the results to a particular postal area within Sydney, Australia.

Read the documentation or view this example full screen.

function initMap() {
  var geocoder = new google.maps.Geocoder;
  var map = new google.maps.Map(document.getElementById('map'), {
    zoom: 8,
    center: {lat: -33.865, lng: 151.209}
  });

  document.getElementById('submit').addEventListener('click', function() {
    geocodeAddress(geocoder, map);
  });
}

function geocodeAddress(geocoder, map) {
  geocoder.geocode({
    componentRestrictions: {
      country: 'AU',
      postalCode: '2000'
    }
  }, function(results, status) {
    if (status === 'OK') {
      map.setCenter(results[0].geometry.location);
      new google.maps.Marker({
        map: map,
        position: results[0].geometry.location
      });
    } else {
