A town or eup is an administrative unit in South Korea; along with township (rural), a town (urban) is one of the divisions of a county, and of some cities with a population of less than 500,000.
The main town or towns in a county—or the secondary town or towns within a city's territory—are designated as towns.
Towns are subdivided into villages.
In order to form a town, the minimum population required is 20,000.
