An information processing device includes an association information acquiring unit, a first position information acquiring unit, and an output control unit. The association information acquiring unit acquires association information in which first identification information used for identifying baggage and second identification information used for identifying an owner of baggage identified by the first identification information are associated with each other. The first position information acquiring unit acquires position information of target baggage that is baggage identified by the first identification information included in the association information. The output control unit causes a mobile terminal held by a target owner who is an owner of the baggage identified by the second identification information associated with the first identification information relating to the target baggage in the association information to output information based on the position information of the target baggage.
