Component using the European Commission (EC) VAT Information Exchange System (VIES) to verify and validate VAT registration numbers in the EU, using PHP and Composer.

The Vies class provides functionality to make a API call to VIES and returns an object VatResponse containing the following information:

• Country code (string): a 2-character notation of the country code
• VAT registration number (string): contains the complete registration number without the country code
• Date of request (DateTime): the date when the request was made
• Valid (boolean): flag indicating the registration number was valid (TRUE) or not (FALSE)
• Name (string): registered company name (if provided by EC member state)
• Address (string): registered company address (if provided by EC member state)

Stated on the European Commission website:

To make an intra-Community supply without charging VAT, you should ensure that the person to whom you are supplying the goods is a taxable person in another Member State, and that the goods in question have left, or will leave your Member State to another MS. VAT-number should also be in the invoice.

On May 25, 2018 the General Data Protection Regulation or GDPR becomes law within all 28 European Member States. Is this VIES service package going to be compliant with GDPR?

In short: yes.

The longer answer is that this VIES package only interacts with the service for VAT ID verification provided by the European Commission. VAT validation is mandatory in European countries and therefor this service is allowed as lawfulness and legal basis. Please read more about this in European DPO-3816.1. This service does not store any data itself or collects more information than what's strictly required by law and provided by the EC VIES service.

When you have implemented this service package in your own project, be sure that you're making sure you're just store the VAT ID, the timestamp of validation, the result of validation and optionally the given validation ID provided by the EC VIES service.

• Minimum PHP version: 7.4
• Guzzle: ^7.9
• Extension: json

Please read the release notes for details.

To install the latest stable version use composer require webatvantage/vies.

To install specifically a version (e.g. 1.0.0), just add it to the command above, for example composer require webatvantage/vies:1.0.0

Here's a usage example you can immediately execute on the command line (or in cron, worker or whatever) as this will most likely be your most common usecase.

<?php

use Webatvantage\Vies\Vies;
use Webatvantage\Vies\Api\VatEuropeApi;

require_once dirname(__DIR__) . '/vendor/autoload.php';

$viesService = new Vies(new VatEuropeApi());

Now that we know the service is alive, we can start validating VAT ID's

$vatResult = $vat = $viesService->validateVat(
    'BE', // Country code
    '0203430576' // VAT ID
);

$vatResult->valid ? 'Valid' : 'Not valid'

try
{
    $valid = $vat = $viesService->validateFormat(
        'BE', // Country code
        '0203430576' // VAT ID
    );
}
catch (ViesException $exception)
{
    $reason = $exception->getMessage()
}

function validateVat(string $countryCode, string $vatNumber, ?string &$error = null): bool
{
    try
    {
        $vat = $viesService->validateVat($countryCode, $vatNumber);
    }
    catch (InvalidCountryCodeException $exception)
    {
        $error = $exception->getMessage();

        return false;
    }
    catch (InvalidVatNumberFormatException)
    {
        $error = $exception->getMessage();

        return false;
    }

    if ($vat->valid === false)
    {
        $error = 'The provided VAT number is not valid';

        return false;
    }

    return true;
}

use Webatvantage\Vies\Vies;

$vatNumber = 'BE0203.430.576';

$vatNumber = Vies::normalizeVat($vatnumber); // BE0203430576

use Webatvantage\Vies\Vies;

$vatNumber = 'BE0203430576';

['country' => $countryCode, 'id' => $vatNumber] = Vies::splitVatId($vatnumber); // ['country' => 'BE', 'id' => '203430576'];

use Webatvantage\Vies\Countries;

$countries = Countries::europeanCountries();

For Greece the international country ISO code is GR, but for VAT IDN's they use the prefix EL. Thanks to Johan Wilfer for reporting this.

Since January 1, 2021 the UK is no longer a member of the European Union and as a result, the VIES service provided by the European Commission no longer validates VAT ID's for the UK. There is one exception though and that is for Northern Ireland (XI) for which VAT ID's can be validated using this library and the EC VIES service.
