- International call out: 00N (where N is the carrier code) followed by the distant country code and telephone number.
- Calling into Korea: +82 XX XXXX YYYY. The leading "0" is dropped when dialling into South Korea from abroad.
- Some 1566/1577/1588 telephone numbers cannot be dialed from abroad.
- Domestic long-distance call: 0NN (where NN is the carrier code) followed by the 0XX area code and XXXX YYYY number. See Domestic long-distance service code and Area code.
- Call to cellular : 01N XXXX YYYY (see Mobile phone number). When phone call is made between unified 010-number subscribers, leading 010 can be dropped (XXXX YYYY).

For example;
- Call 02-312-3456 within Seoul: 312-3456
- Call 02-312-3456 from elsewhere: 02-312-3456
- Call 051-212-3456 within Busan: 212-3456
- Call 051-212-3456 from elsewhere: 051-212-3456
- Call 02-312-3456 from abroad: +82-2-312-3456
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)
