A plurality of information processing apparatuses are each assigned an apparatus identification code and a group identification code. In a database of a server apparatus, when or before each of the information processing apparatuses is sold to a customer, a correspondence relationship between the apparatus identification code and the group identification code assigned to the information processing apparatus is stored. When having communicated with any one of the information processing apparatuses sold to a customer, the server apparatus acquires from the database a group identification code corresponding to the apparatus identification code received from the information processing apparatus, and provides a service based on the acquired group identification code. |
