A method for foiling cellular telephone cloning by verifying subscribers of a cellular communications network is accomplished by having each subscriber provide a local telephone number, typically not their own, to the cellular telephone company and long distance carrier for each cellular telephone they own in order to verify legitimate subscribers. Shortly after power-up of the cellular telephone, a subscriber either invokes an automatic dialer or manually dials the verification telephone number. A computer in the cellular network receives the subscriber's first call after power-up and verifies the dialed telephone number against the verification telephone number stored in a database corresponding to the electronic serial number of that cellular telephone. In response to a match, the cellular network transmits a single ring to the subscriber telephone as confirmation of a validation; otherwise a message requesting enablement of the cellular telephone is transmitted to the subscriber telephone.
