A South Korean mobile telephone identifier typically comprises eleven digits, structured as 010-XXXX-YYYY. The initial ‘010’ universally designates a mobile service. The subsequent four digits (XXXX) represent a subscriber’s unique identifier within the network, while the final four digits (YYYY) further differentiate the specific subscriber. An instance would appear as 010-1234-5678.
This numbering system facilitates efficient routing of calls and text messages within South Korea’s telecommunications infrastructure. Its standardized format aids in verification processes, subscription management, and lawful identification. Historically, variations existed, but the ‘010’ prefix became the standard, streamlining mobile communication and solidifying its role in the countrys digital landscape.
