ENUM (E.164 Number Mapping)

ENUM (E.164 Number Mapping) is a system that connects traditional phone numbers to internet-based communication services. It converts a standard phone number into a unique digital address that can be used to find all related communication methods—like Voice over IP (VoIP), email, or instant messaging—via the internet. Essentially, ENUM bridges the gap between phone networks and internet services, making it easier to reach someone using their regular number across different communication platforms without needing multiple contact details.
