If customers enter company and their vat number in Address step, vat number is not displayed in anywhere except when you do some "extra digging".
Order info / Billing Address has no vat number
The only way for you to find the vat number is to go to Order in backend, expand Billing address data tab and look if the vat is entered or now. This is to much time consuming for caretaker to check if it exist or not - but showing data in Billing Address info it would make world better for order caretaker and also customer can check their vat number correctness at Review step.
I suppose the "hcard_org" in Address model can be extended since those two informations are related.
