An information processing system includes image capturing devices, an information processing apparatus, and processing circuitry. The image capturing devices are disposed to capture images of a management area. The information processing apparatus recognizes a code image corresponding to an object to be managed in the management area, from a captured image captured by the image capturing devices, and manages a location of the object. The processing circuitry sets address identification information associated with position information in the management area to a region of the captured image; based on recognition of the code image in the region, manages the position information associated with the address identification information set for the region, as a location of the object corresponding to the code image; and commonly sets one piece of the address identification information associated with the position information, for regions of different captured images captured by the image capturing devices.
