Telephone numbers in South Korea are organised and assigned using the following scheme.
For example;
South Korea uses an open dialing plan with a total length (including 0) of 9 to 11 digits and, within city, subscriber numbers 7 to 8 digits long. Dialing from mobile phones to any type of phone except 010 numbers, the area code must be included.
In 1998, telephone numbers in Seoul starting with 2 and 6 added more digit (02-2XX-YYYY to 02-22XX-YYYY, 02-6XX-YYYY to 02-26XX-YYYY). Before area codes were shortened from 4 digit to 2~3 digit in June 2000, there were 1 digit exchange number (usually "2") with some 2 digit exchange numbers so some phone numbers like 0347-61-XXXX, 0443-2-XXXX or 0525-40-XXXX existed. (now 031-761-XXXX, 043-652-XXXX and 055-340-XXXX)
Before June 2000, South Korea used two- to four-digit area codes.
It is not necessary to dial any carrier prefix before making a domestic long-distance call. These prefixes are needed only when you want to choose a different carrier other than your default long-distance carrier (usually the same company that provides your phoneline).
