Abstract: The disclosure relates to a 5G communication system or a 6G communication system for supporting higher data rates beyond a 4G communication system such as long term evolution (LTE). In a wireless communication system, a method performed by a first user equipment (UE) may include: obtaining at least one phone number from a plurality of usable sources, classifying, based on a usage state, the at least one phone number into one of a permanent state, a temporary state, or an invalid state, and transmitting a session initiation protocol (SIP) message including information associated with the at least one classified phone number to a second UE.
