Abstract: A device registration work assistance system includes a plurality of devices installed at building installation locations, a management apparatus, and a notification apparatus. The management apparatus estimates arrangement information of the devices based on information relating to electromagnetic waves acquired by the devices performing wireless communication with each other, and calculates one or more candidates for the device installed at the installation location by collating the arrangement information with the position information of the installation locations. In a case in which the management apparatus determines that the device actually installed at the installation location cannot be identified from the one or more candidates for the device installed at the installation location, the notification apparatus notifies the position information of the installation location and the unique information of the one or more candidates for the device installed at the installation location.
