A method of providing an aliased telephone number provided. A user may request an alternate telephone number to protect his privacy when making calls. When the user transmits a call, a service provider detects that the call should be linked with an aliased telephone number. The provider may then substitute the aliased number for the originating number such that the recipient sees the aliased number on a caller identification module. Likewise, where someone sends a call to an aliased number, the service provider may cross reference the aliased number with an actual telephone number and either augment data information associated with the call with the actual number, or replace the aliased number with the actual number. The aliased number may be time sensitive and may have an expiration date. The system and method allow users to obtain telephone numbers for time-limited events.
