# ISO 3166-2:KR

ISO 3166-2:KR is the entry for South Korea (officially the Republic of Korea) in ISO 3166-2, part of the ISO 3166 standard published by the International Organization for Standardization (ISO), which defines codes for the names of the principal subdivisions (e.g., provinces or states) of all countries coded in ISO 3166-1.
Currently for South Korea, ISO 3166-2 codes are defined for one special city, six metropolitan cities, seven provinces, two special self-governing provinces and one special self-governing city. All of them are province-level subdivisions.

* 11: special city
* 26–31: metropolitan cities
* 41–48: provinces
* 49: special self-governing province
* 50: special self-governing city
