A communication device (200) operates on a plurality of communication networks (104, 110) and utilizes a method (400) for reformatting a caller identification received from one communication network (110) to match the caller identification format of a second communication network (104). The reformatted caller identification can be used to match an address book entry (318) or for dialing a call using the second communication network (104). A communication controller (300) is also used to provide the reformatted caller identification in an alternate embodiment.
