One issue with using officially-issued ID numbers (I assume that a VAT number is a Value-Added Tax number assigned by the UK government) is that there is no world-wide registry guaranteeing that the IDs are unique.  A given ID might mean one company in the UK, a different one in Germany, and yet another company in Japan, for example.  So, any such tag would need to include a country code.
