Dialing Tips

  • Remove the leading 0: When dialing internationally, drop the trunk prefix (0) that is used for domestic calls in South Korea.

  • Verify the number length: Numbers in South Korea have 9 or 10 digits for mobiles and 5 to 10 for landlines after +82. If your call does not connect, check that no digit is missing or doubled.
  • Save contacts in international format: Always store phone numbers with the full +82 prefix so they work from any country.
