Question

我来自哪里，我不需要缴纳增值税（增值税）。但我正在做的一个项目需要其输入才能合法地完成交易。

在哪里可以找到API，我可以从增值税税号中获取相关信息（地址，公司名称等）？我想用它来自动填充表单，因为没有更好的方法来吓跑客户而不是让他工作。

评论中提到的VIES有一个API。而且我已经实现了你所要求的，主要是出于同样的原因。和它的'PHP。你走了：

class VatValidator {

const validVatId = 'valid';
const invalidVatId = 'invalid';

/**
 *
 * The european commission (ec) provides a validation database for VAT Id's, which can be accessed via WSDL.
 * We check the given VAT against that Database.
 *
 * Actually that is more reliable than any captcha !!!
 *
 *  * only companies have one
 *  * the code can not be "brute forced"
 *  * simple mass requests can be cut off easily
 *
 * @param String $requestedVatId entire VAT Id including country code
 * @param string $company optional Company Name
 * @param string $city optional company city
 * @return Multiple false on error, String self::validVatId or String self::invalidVatId according to state.
 */
public static function validateVATID($requestedVatId, $company=null, $city=null)
{
    $ret = false;
    $ecUrl = "http://ec.europa.eu/taxation_customs/vies/checkVatService.wsdl";
    $vatid = str_replace(array(' ', '.', '-', ',', ', '), '', trim($requestedVatId));
    $cc = substr($vatid, 0, 2);
    $vn = substr($vatid, 2);
    $client = new SoapClient($ecUrl);

    if($client)
    {
        $params = array('countryCode' => $cc,
                        'vatNumber' => $vn,
        );

        /*
         * simple request only since we do not get any further information anyway.
         *
         * with $r = $client->checkVatApprox($params);
         * we could:
         *
                    'requesterCountryCode' => 'XXX',
                    'requesterVatNumber' => 'XXX' // Own ID!!

        if ( !empty($company) )
            $params['traderName'] = $company;
        if ( !empty($city) )
            $params['traderCity'] = $city;

        $params["traderCompanyType"] = 1;
        $params["traderStreet"] = 'xyz';
        $params["traderPostcode"] = '1234';
        */

        try
        {
            //$r = $client->checkVatApprox($params);
            $r = $client->checkVat($params);
            if($r->valid == true)
            {
                logMessage(Constants::$debug, 'valid: ' . $vatid);
                $ret = self::validVatId;
            }
            else
            {
                logMessage(Constants::$debug, 'invalid: ' . $vatid);
                $ret = self::invalidVatId;
            }

            // This foreach shows every single line of the returned information
            //              foreach($r as $k=>$prop)
            //              {
            //                  logMessage(Constants::$debug, $k.': '.$prop);
            //              }
            //logMessage(Constants::$debug, print_r($r, true));

        } catch(SoapFault $e) {
           logMessage(Constants::$debug, 'Error, see message: '.$e->faultstring);
           $ret = $e->faultstring;
        }
    }
    else
    {
        logMessage(Constants::$debug, 'cannot connect to ' . $ecUrl);
        $ret = 'CONNECTERROR';
    }
    return $ret;
}
}

代码中的“XXX”可能是您自己的增值税ID，以便通过输入您自己的ID来防止有点欺诈......

我在哪里可以找到VAT API？
