One page isn’t nearly enough space to list all of the uses for numbering. But here goes: validation numbers for concerts or theaters, trade shows or hotel rooms, car rentals, coupons, gift cards, and lottery tickets. And that’s just a start! We can number on paper, plastic, card stock and a wide variety of other substrates. Numbering helps you maintain order, informs you of response location, discourages counterfeiting and retains interest. It all adds up. You can really count on numbering.
