Free IP Locator API - Convert IP Addresses to Zip Codes with PHP

If you just want a free site to use:
IP Address Locator with Map


If you want a quick PHP solution, try this:

$ip = 'xxx.xxx.xxx.xxx';
var_dump(json_decode(file_get_contents("https://freegeoip.net/json/$ip"),true));



If you want quick responses, you can install the freegeoip server on ubuntu. This will give you your own personal IP locator service to use privately (or publicly if you are a nice guy):
