How to dial a phone number in Jeju Republic of Korea?
From outside Republic of Korea, a caller would dial their international call prefix (typically 00 in Europe and 011 in North America), followed by 82 (the country code for
Republic of Korea), then 64 the 2-3 digit area code of the place you're calling (Jeju) minus the trunk code '0', and finally the local number minus the trunk code '0'. All local telephone numbers dialled within Republic of Korea must use the leading '0' and the area phone code, even when calling locally.
