South Korea Phone Number Format

Country code +82 — Complete guide to South Korea phone number formats, mobile and landline structures, and area codes.

Number Format Overview

Phone numbers in South Korea use the international country code +82. When dialing from outside South Korea, you must include this country code before the local number.

Dialing Tips

  • Remove the leading zero: When dialing internationally, drop the trunk prefix (usually 0) that is used for domestic calls in South Korea.
  • Use the + notation: From a US mobile phone, use +82 instead of 011 82.
  • Verify the number length: Make sure you have the correct number of digits. If your call does not connect, check whether you need to add or remove an area code digit.
  • Save contacts in international format: Always store phone numbers with the full +82 prefix so they work from any country.
