Maching numbers on all 3 portions make it easy to match a customer's claim check to the keys and vehicles fast. Made of heavy card stock, the Vehicle ID Numbers include a hang tag with perforated key tag and claim check. Two sided printing enables you to see the status of each vehicle at a glance. (Red side means the vehicle is not repaired. Green means the job is done.) An easy and effective way to organize the service dispatch area at your dealership or repair shop.
