A GTIN is a string of digits that uniquely identifies a trade item (a product that is bought and sold). A GTIN is globally unique, meaning that no two products in the world share the same GTIN.

This library provides a straightforward way by which a number can be determined to be a valid GTIN or suspected of being invalid in some way.

via Composer

$ composer require real-digital/gtin-validator

// create a valid GTIN
$value = '4006381333931';
$gtin = Gtin\Factory::create($value);


// handle errors
$value = 'any invalid value';
try {
    $gtin = Gtin\Factory::create($value);
} catch (Gtin\NonNormalizable $e) {
    // ...

// check whether GTIN is valid
$value = '4006381333931';
$isValid = Gtin\Factory::isValid($value);

Each created GTIN implements a common interface. This is a complete list of its methods:
