Sorry. The stamping machine in Ball Plant 3 is only designed to handle single and double digits. They would have to replace the entire equipment for this to happen. The other issue is unlike personalized logos which are done post-production, they do not change numbers for one individual order, they print a large batch at each number and put them on the shelf until someone orders that number. You can see and purchase all 00-99 at the TT Store at the end of the Ball Plant tour. The volume of balls printed through 999 that likely would not be purchased would be a waste and just drive up overhead costs that then would be passed on to the retail price of balls. Hope this helps.
