A bearing component is an annular member with a two-dimensional code which has a shape with a maximum circumferential dimension longer than a maximum radial dimension or a maximum axial dimension. An individual identification method for the bearing component includes the steps of imaging while rotating the bearing component, detecting a line pattern of the two-dimensional code from a captured image, recognizing the two-dimensional code based on an extension direction of the line pattern, extracting corresponding registration information by referring to a database based on information of the two-dimensional code, and identifying the bearing component according to the extracted registration information.
