Business::Tax::VAT::Validation - A class for european VAT numbers validation.
use Business::Tax::VAT::Validation; my $hvatn=Business::Tax::VAT::Validation->new(); # Check number if ($hvatn->check($VAT, [$member_state])){ print "OK\n"; } else { print $hvatn->get_last_error; }
This class provides an easy api to check european VAT numbers' syntax, and if they has been registered by the competent authorities.
It asks the EU database (VIES) for this, using its SOAP interface methods.
$hvatn=Business::Tax::VAT::Validation->new(); If your system is located behind a proxy : $hvatn=Business::Tax::VAT::Validation->new(-proxy => ['http', 'http://example.com:8001/']); Note : See LWP::UserAgent for proxy options.
@ms=$hvatn->member_states;
If you want to test a VAT number format ouside this module, e.g. embedded as javascript in a web form.
%re=$hvatn->regular_expressions;
returns
( AT => 'U[0-9]{8}', ... SK => '[0-9]{10}', );
$ok=$hvatn->check($vatNumber, [$countryCode]);
You may either provide the VAT number under its complete form (e.g. BE-123456789, BE123456789) or specify the VAT and MSC (vatNumber and countryCode) individually.
Valid MS values are :
AT, BE, BG, CY, CZ, DE, DK, EE, EL, ES, FI, FR, GB, HU, IE, IT, LU, LT, LV, MT, NL, PL, PT, RO, SE, SI, SK
$ok=$hvatn->local_check($VAT, [$member_state]);
%infos=$hvatn->informations();
my $err = $hvatn->get_last_error_code(); my $txt = $hvatn->get_last_error();
Possible errors are :
If error_code > 16, you should temporarily accept the provided number, and periodically perform new checks until response is OK or error < 17 If error_code > 256, you should temporarily accept the provided number, contact the author, and perform a new check when the software is updated.
