About South Korea Phone Numbers

Korean mobile numbers start with 010, followed by 8 digits (total 11 digits). Older prefixes 011, 016, 017, 018, 019 still exist but 010 is dominant. Landlines vary by area.

How to Dial South Korea Phone Numbers

To call a South Korea phone number, the exact format depends on where the call starts. Domestic mobile calls usually keep the leading 0, while international calls to South Korea use the +82 country code instead.

  • Within South Korea: Dial the full national number, including the leading 0 for standard domestic calls.
    Example: 010-1234-5678
  • From abroad to South Korea: Dial +82 followed by the national number without the leading 0.
    Example: +82 10-1234-5678
  • From South Korea to other countries: Dial an international access prefix such as 001, 002, or 008, then the country code and full phone number.
    Example: 001 1 212 555 0123

Note: Korean domestic mobile numbers usually begin with 0, but that prefix is dropped in international format.

Special Cases

Some numbers and prefixes in South Korea have special rules or reserved uses.

  • Emergency Numbers

    112119

    South Korea uses 112 for police emergencies and 119 for fire, rescue, and ambulance emergencies. These short codes are dedicated emergency access numbers, not regular subscriber numbers.

  • Tourist and Foreigner Help Lines

    13301345

    South Korea provides special short help lines such as 1330 for tourist information and 1345 for immigration and foreigner support. These are service hotlines rather than geographic phone numbers.

  • Police Consultation and Reporting Numbers

    182

    Korean police also operate dedicated consultation and reporting lines separate from 112 for non-emergency matters. These short codes are allocated for public service access rather than for standard subscriber use.
