Abstract
The object of the present application is to provide a method and device for verifying a communication number. Compared with the prior art, the present application includes: a user equipment transmitting a verification request to a network device; the network device transmitting an auxiliary verification number to the user equipment based on the verification request; the user equipment initiating a verification call to the auxiliary verification number via the communication number; the network device obtaining a call record of the auxiliary verification number and determining the verification result based on the call record of the auxiliary verification number. In this way, operator fees would not be caused at both the user equipment and the network device, thus greatly saving costs.
