A system and method for proactively detecting cloning fraud in a cellular mobile telephone environment are discussed. Information is collected which corresponds to registration notifications of the cellular telephones as they operate within the cellular mobile telephone environment. The registration information is used to detect time-space peculiarities. Specifically, registrations having the same mobile identification number and occurring in different mobile switching centers within a predetermined time interval are identified. This time interval, based on a reasonable travel time between cells covered by the different mobile switching centers where the registrations originated, is used as a threshold for detecting cloning fraud.
