The Tumi Tracer is an exclusive, complimentary program that helps reunite Tumi customers with their lost or stolen items. The core of the program is a unique 20-digit individual product number printed on a special metal plate that is permanently affixed to Tumi products. That number, along with the owner's contact information, is entered into our Tracer database when a bag is registered with us, and used to help aid in the recovery of lost or stolen items that are reported to us.
