A target identification system includes: one or more optical receivers (at least one of a first optical receiver or a second optical receiver) which receive outgoing light from a moving body, the outgoing light including an optical signal indicating identification information (first information) for identifying the moving body; a controller connected to the one or more optical receivers; and a wireless communicator connected to the controller. When the one or more optical receivers receive the outgoing light, the controller obtains the identification information, and when the controller receives radio waves including the identification information and service information (second information) via the wireless communicator, in the case where the identification information included in the outgoing light matches the identification information included in the radio waves, the controller obtains the service information, the service information being information necessary for the moving body to receive a predetermined service.
