• 1 Are you looking to display the area associated with each postal code as a shape on the map or do you just want to display a single marker for each postal code, located somewhere within the postal code area? – hennes Commented Aug 30, 2014 at 13:58
• I want to display area pointing with marker on th same map for all postal codes. – Maria Commented Aug 30, 2014 at 14:03
• I want to provide postal code and google map should search for it and show me map for all postal code in the same place together. – Maria Commented Aug 30, 2014 at 14:04
• How are you planning on "providing the postal codes"? The "best" solution is to geocode them offline and include the geographic coordinates. You can geocode them on page load, but if there are more than ~10, you will have to handle the API rate limit (the OVER_QUERY_LIMIT status response). – geocodezip Commented Aug 30, 2014 at 17:20

As far as I understood you have an array of postal codes like this.

var postalCodes = [
    '10405', // Berlin
    ...
];

You want to convert each of these ZIP codes to a marker on the map. For this purpose you can use Google's geocoding API. All you need to do is create a GeoCoder object and call its geocode function with the postal code and a country hint.

geocoder.geocode({
    address: postalCode,
    region: countryHint // e.g. 'DE' for Germany
}, function(result, status) {
    // Create marker
}

A working example: JSFiddle

HTML

<div id="map-canvas"></div>

JavaScript

var postalCodes = [
    '01067', // Dresden
    '10405', // Berlin
    '20359', // Hamburg
];

function initialize() {
    var map = new google.maps.Map(document.getElementById('map-canvas'), {
        center: new google.maps.LatLng(52.5167, 12.1833),
        zoom:   6
    });

    var geocoder = new google.maps.Geocoder();

    google.maps.event.addListenerOnce(map, 'tilesloaded', function() {
        for (var i = 0; i < postalCodes.length; ++i) {
            geocoder.geocode({
                address: postalCodes[i],
                region: 'DE'
            }, function(result, status) {
                if (status == 'OK' && result.length > 0) {
                    new google.maps.Marker({
                        position: result[0].geometry.location,
                        map: map
                    });
                }
            });
        }
    });
}

google.maps.event.addDomListener(window, 'load', initialize);

This is the reference to use API properly.

Here is the logic, you have to create multiple LatLng objects with latitudes and longitudes.

Create a map object.

Create multiple marker objects for those LatLag objects and then bind those markers to map object.
