A small PHP library for validating VAT identification numbers (VATINs).

This library is available on Packagist:

$ composer require ddeboer/vatin

If you want to use this library in a Symfony application, you can use the VatinBundle instead.

Validate a VAT number’s format:

use Ddeboer\Vatin\Validator;

$validator = new Validator;
$bool = $validator->isValid('NL123456789B01');

Additionally check whether the VAT number is in use, with a call to the VAT Information Exchange System (VIES) SOAP web service:

use Ddeboer\Vatin\Validator;

$validator = new Validator;
$bool = $validator->isValid('NL123456789B01', true);
