The invention relates to the mobile Internet verification service and aims to provide a number verification service realization method through voice call. A verification platform in an intelligent network realization mode is employed, and the verification platform comprises a trigger service module, a call service module and a verification module. The method comprises steps that a call is actively initiated by a verified user for the verification platform, calling routing is analyzed according to a calling switch address of a call trigger message, when a verification access number and a user call number are same network numbers and an active calling side originating office is an end office, authenticity verification of the user call number passes, and incoming call number ownership of the user is confirmed. Compared with the prior art, the method is advantaged in that introducing a signaling monitoring subsystem is not needed, system configuration is simplified, and system complexity is reduced; based on relatively stable characteristics of the switch address in the communication network, verification accuracy is improved.
