Abstract: A system, method, and apparatus are provided for sending a calling party number for a roaming mobile station to a called party. The roaming mobile station subscriber dials an abbreviated number, corresponding to a full directory phone number, which is received by a visited public land mobile network (V-PLMN) . The V-PLMN queries a service control point (SCP) to determine routing instructions corresponding to the abbreviated number. During the query, the SCP stores the calling party number in a register. The SCP transmits the routing instructions appended with an index and an identification number for the SCP. The V-PLMN uses the route instructions to route the call generated by the mobile station to a switching point serving the called party. The switching point then uses the index to retrieve the stored called party number from the SCP.
