Hello,

This add-on is unfortunately not working for VAT-Numbers from Greece.

(It seems a little bit strange to me, I'm the first, who noticed this, but I haven't found any information about this 'bug' in this thread - please excuse me, if I've missed something)

The problem is: Greek VAT-Numbers are an exception, they're starting with 'EL', but not with 'GR' (short Country cobe by ISO)

The problem can be fixed, by adding the following code:

Code:
$country_iso_code_2 = $country_iso_code_2 == 'GR' ? 'EL' : $country_iso_code_2;
after

Code:
$country_iso_code_2 = $this->getCountryIsoCode2($countries_id);
in validateVatNumber method (file Vat4EuAdminObserver.php)


...Or you can simply replace ISO-2 code for Greece (from "GR" to "EL") :-)
