Tab 3 - Business Address needs a physical address: Country, Street Address 1, optional Street Address 2, City, State/Province/Region and Postal Code, then Save. P.O. boxes are not accepted. The fields are pre-filled from your company address settings where available. If you later change the Country, Sprwt deletes the old address record and creates a new one; changing other fields simply updates it. The saved address is also attached to your profile as the supporting address document used during evaluation.
