Lookup City and State by Zip Google Geocode Api [closed]

Answer 1

I found a couple of ways to do this with web based APIs. I think the US Postal Service would be the most accurate, since Zip codes are their thing, but Ziptastic looks much easier.

Using the US Postal Service HTTP/XML API

According to this page on the US Postal Service website which documents their XML based web API, specifically Section 4.0 (page 22) of this PDF document, they have a URL where you can send an XML request containing a 5 digit Zip Code and they will respond with an XML document containing the corresponding City and State.

According to their documentation, here's what you would send:

http://SERVERNAME/ShippingAPITest.dll?API=CityStateLookup&XML=<CityStateLookupRequest%20USERID="xxxxxxx"><ZipCode ID= "0"><Zip5>90210</Zip5></ZipCode></CityStateLookupRequest>

And here's what you would receive back:

<?xml version="1.0"?> 
<CityStateLookupResponse> 
    <ZipCode ID="0"> 
        <Zip5>90210</Zip5> 
        <City>BEVERLY HILLS</City> 
        <State>CA</State> 
    </ZipCode> 
</CityStateLookupResponse>

USPS does require that you register with them before you can use the API, but, as far as I could tell, there is no charge for access. By the way, their API has some other features: you can do Address Standardization and Zip Code Lookup, as well as the whole suite of tracking, shipping, labels, etc.

Using the Ziptastic HTTP/JSON API (no longer supported)

Update: As of August 13, 2017, Ziptastic is now a paid API and can be found here

This is a pretty new service, but according to their documentation, it looks like all you need to do is send a GET request to http://ziptasticapi.com, like so:

GET http://ziptasticapi.com/48867

And they will return a JSON object along the lines of:

{"country": "US", "state": "MI", "city": "OWOSSO"}

Indeed, it works. You can test this from a command line by doing something like:

curl http://ziptasticapi.com/48867 

Answer 2

couple of months back, I had the same requirement for one of my projects. I searched a bit for it and found out the following solution. This is not the only solution but I found it to one of the simpler one.

Use the webservice at http://www.webservicex.net/uszip.asmx.
Specifically GetInfoByZIP() method.

You will be able to query by any zipcode (ex: 40220) and you will have a response back as the following...

<?xml version="1.0" encoding="UTF-8"?>
 <NewDataSet>
  <Table>
   <CITY>Louisville</CITY> 
   <STATE>KY</STATE> 
   <ZIP>40220</ZIP> 
   <AREA_CODE>502</AREA_CODE> 
   <TIME_ZONE>E</TIME_ZONE> 
  </Table> 
</NewDataSet>

Hope this helps...

function getCityState($zip, $blnUSA = true) {
    $url = "http://maps.googleapis.com/maps/api/geocode/json?address=" . $zip . "&sensor=true";

    $address_info = file_get_contents($url);
    $json = json_decode($address_info);
    $city = "";
    $state = "";
    $country = "";
    if (count($json->results) > 0) {
        //break up the components
        $arrComponents = $json->results[0]->address_components;

        foreach($arrComponents as $index=>$component) {
            $type = $component->types[0];

            if ($city == "" && ($type == "sublocality_level_1" || $type == "locality") ) {
                $city = trim($component->short_name);
            }
            if ($state == "" && $type=="administrative_area_level_1") {
                $state = trim($component->short_name);
            }
            if ($country == "" && $type=="country") {
                $country = trim($component->short_name);

                if ($blnUSA && $country!="US") {
                    $city = "";
                    $state = "";
                    break;
                }
            }
            if ($city != "" && $state != "" && $country != "") {
                //we're done
                break;
            }
        }
    }
    $arrReturn = array("city"=>$city, "state"=>$state, "country"=>$country);

    die(json_encode($arrReturn));
}

Use the GeoCoding API

For example, to lookup zip 77379 use a request like this:

https://maps.googleapis.com/maps/api/geocode/json?address=77379&sensor=true&key=YOUR_GOOGLE_PLATFORM_API_KEY
