A telephone identification sequence composed of twelve numerical figures is used in specific international telecommunication contexts. It serves to uniquely identify a subscriber’s connection point within a global network. An example would be 1-242-300-XXXX, where ‘1’ represents the country code, ‘242’ the area code, ‘300’ the central office code, and ‘XXXX’ the subscriber number.
Such numbering systems facilitate direct dialing across geographical boundaries, contributing significantly to international commerce and personal communication. Their implementation represents a significant advancement over manual switchboard operations, streamlining the process of establishing connections between distant parties. The structured format ensures efficient routing and delivery of voice and data traffic.
