PHP library to validate VAT numbers.


Open a command console, enter your project directory and execute the following command to download the latest stable version of this library:

$ composer require antalaron/vat-number-validator

This command requires you to have Composer installed globally, as explained in the installation chapter of the Composer documentation.

Basic usage

To validate a VAT number:

use Antalaron\Component\VatNumberValidator\VatNumber;
use Symfony\Component\Validator\Validation;

$validator = Validation::createValidator();
$violations = $validator->validate('ATU37675002', new VatNumber());

if (0 !== count($violations)) {
    foreach ($violations as $violation) {
        echo $violation->getMessage().'<br>';

You can add your own VAT validator via extraVat option:

$violations = $validator->validate('11', new VatNumber(['extraVat' => function ($number) {
    return 0 !== preg_match('/^(\d{2})$/', $number);
