Overview of South Korea's +82 19 Mobile Prefix
The +82 19 prefix is a non-geographic mobile network code within the South Korean national numbering plan, administered under ITU-T E.164 guidelines. Unlike geographic area codes that correspond to specific cities or provinces, the 19 prefix is allocated exclusively for mobile communication services, enabling subscribers to be reached regardless of their physical location. This prefix is assigned to mobile network operators (MNOs) and mobile virtual network operators (MVNOs) that provide nationwide 3G, 4G LTE, and 5G services.
Technical Formatting and Dialing Procedures
South Korean mobile numbers typically consist of 10 or 11 digits, including the leading national destination code (NDC). For the 19 prefix, the standard national format is 019-XXXX-XXXX (where X represents a digit), resulting in a total length of 11 digits when including the leading '0'. Internationally, callers must dial +82 19 XXXX XXXX, omitting the leading '0' of the NDC. For example, a national number 019-1234-5678 would be dialed as +82 19 1234 5678 from abroad.
When calling within South Korea, users simply dial the full 11-digit number, including the leading '0'. For international callers, the plus sign (+) indicates the international access code, which varies by country (e.g., 011 from the US, 00 from most European countries). It is essential to use the correct international format to ensure proper routing through the PSTN and mobile networks.
Service Characteristics and Portability
Numbers under the 19 prefix are non-geographic, meaning they are not tied to a specific region. This allows subscribers to retain their numbers when moving across the country. Mobile number portability (MNP) is fully implemented in South Korea, enabling users to switch between MNOs or MVNOs while keeping their existing 19-prefix number. However, the prefix may not always indicate the current service provider due to porting; it reflects the original allocation.
These numbers support full voice, SMS, and data services, including international roaming. SMS and voice calls to 19 numbers are routed through the home network's MSC (Mobile Switching Center) and HLR (Home Location Register). For VoIP or international calls, interconnection agreements ensure seamless termination.
Regulatory and Usage Notes
The 19 prefix is part of the national numbering plan managed by the Korea Communications Commission (KCC). It is distinct from geographic codes (e.g., 02 for Seoul) and special service codes (e.g., 080 for toll-free). While most 19 numbers are used for personal mobile services, some may be assigned to MVNOs offering data-only plans or IoT devices. Callers should be aware that charges for calling 19 numbers depend on their own carrier's international or domestic rate plan, as these are standard mobile numbers, not premium or toll-free lines.
