Vat-Validation is a PHP class allowing you to

• Validate a VAT number
• Retrieve information like the name or the address of the company

The data is extracted from a European Commission webservice

It actually only works for European countries

require_once('vatValidation.class.php'); $vatValidation = new vatValidation( array('debug' => false)); $vatValidation->check($countryCode, $vatNumber)); 

Your instance can now access the following methods:

$vatValidation->isValid() $vatValidation->getName() $vatValidation->getDenomination() $vatValidation->getAddress() 

You'll find an example in the example.php file

PHP with Soap enabled
