A registration device includes a reader, a specification unit, a determination unit, a setting unit and a call registration unit. The specification unit specifies a plurality of candidate floors on the basis of a two-dimensional barcode. In a case where it is determined by the determination unit that a candidate floor that matches an installation floor is included, the setting unit sets the candidate floor as a departure floor and sets another candidate floor included in the plurality of candidate floors as a destination floor. The call registration unit registers a call for a car on the basis of the departure floor and the destination floor set by the setting unit.
