API Client for Validating Tax Identification Number.

Introduction

With this package you can get tax offices by city plates and validate tax identification numbers on GIB (Gelir İdaresi Başkanlığı).

This package requires PHP 7.4 or higher.

Installation

You can install the package via composer:

composer require tarfin-labs/tax-identification-number

Usage

Listing tax offices by city plate:

use TarfinLabs\TaxIdentificationNumber\Validation;
use TarfinLabs\TaxIdentificationNumber\Exceptions\NotFoundException;

try {
    $offices = Validation::init()->getTaxOfficesByCityPlate(34);
} catch (NotFoundException $e) {
    echo $e->getMessage();
}

Output:

[
    [
        "code" => "034XXX",
        "name" => "TAX OFFICE NAME 1",
    ],
    [
        "code" => "034XXY",
        "name" => "TAX OFFICE NAME 2
    ],
]

Validating a tax identification number:

use TarfinLabs\TaxIdentificationNumber\Validation;

try {
    $response = Validation::init()->validate(1234567890, '034455');
    
    $response->isValid(); // boolean
    $response->getStatus(); // "1"
    $response->getTckn(); // ""
    $response->getStatusText(); // "FAAL"
    $response->getTaxNumber(); // "123123123"
    $response->getTaxOfficeNumber(); // "034455"
    $response->getCompanyTitle(); // "ACME INC."
} catch (\Throwable $e) {
    echo $e->getMessage();
}

If you want to validate a TCKN for a sole proprietorship, you need to give TCKN (11 characters) as first parameter to validate() method.

use TarfinLabs\TaxIdentificationNumber\Validation;

try {
    $response = Validation::init()->validate(12345678902, '034455');
    
    $response->isValid(); // boolean
    $response->getStatus(); // "1"
    $response->getTckn(); // "12345678902"
    $response->getStatusText(); // "FAAL"
    $response->getTaxNumber(); // "9999999999"
    $response->getTaxOfficeNumber(); // "034455"
    $response->getCompanyTitle(); // "METİN KAYA"
} catch (\Throwable $e) {
    echo $e->getMessage();
}
