Regarding VAT numbers verification, this is currently not implemented in FA, however I agree it would be usefull. Anyway if you  use FA via internet, there is no need for any EU VAT numbers/formats database: there is online service available HERE where you can check VAT numbers status  at any time smile.

VIES verification
For many, this can be very helpful.
