A computerized method for managing phone numbers stored in a communication device, the communication device communicates with a communication service terminal provided by a telecommunication company. The communication device sends a request message for requesting to acquire a usage state of each of the phone numbers to the communication service terminal, and then detects which of the phone numbers have the usage state that matches one or more predetermined states. Any detected phone number which usage state matches the one or more predetermined states is deleted from the communication device.
