README

You may want to use https://github.com/loophp/tin instead.

A library to validate TIN numbers for individuals. This is based on a java library, this is why the code does not reflect best practices in php.

Supported countries are:

• Austria (AT)
• Belgium (BE)
• Bulgaria (BG)
• Croatia (HR)
• Cyprus (CY)
• Czech Republic (CZ) - no check digit (but possible czechphp/national-identification-number-validator)
• Denmark (DK)
• Estonia (EE)
• Finland (FI)
• France (FR)
• Germany (DE)
• Greece (GR) - only size
• Hungary (HU)
• Ireland (IE)
• Italy (IT)
• Latvia (LV) - no check digit
• Lithuania (LT)
• Luxembourg (LU)
• Malta (MT) - no check digit
• Netherlands (NL)
• Poland (PL)
• Portugal (PT)
• Romania (RO) - no check digit
• Slovakia (SK) - only structure
• Slovenia (SI)
• Spain (ES)
• Sweden (SE)
• United Kingdom (UK) - only structure

If your country is not there, feel free to open an issue with your country code and a link to the specification. Ideally, if you can provide a PR with the algorithm and the test that would be even better :-)

Installation

Run

$ composer require lekoala/tin

Usage

To simply check the validity of a number

$result = TINValid::checkTIN($countryCode, $number);

If you want to get the reason why a number is invalid, you can use

try {
    TINValid::validateTIN($countryCode, $number);
}
catch(TINValidationException $e) {
    
}

If you want to see if a country is supported or not, you can simply use

$result = TINValid::isCountrySupported('be');
