The administrative districts in Jeongseon County began with seven myeons in 1906 when a national reorganization of administrative districts led to the implementation of the 13-province system. In 1973, Jeongseon-eup and the Sabuk branch office under its jurisdiction were elevated to the status of eup, and in 1980, Sindong was upgraded from myeon to eup. In 1985, Sabuk-eup was divided into two eups, Gohan-eup and Sabuk-eup, and the elevation of the Buk-myeon branch office to Bukpyeong-myeon in 1986 completed the development of the present state of four eups and five myeons. As Dong-myeon and Buk-myeon(East and North myeon, respectively), which had been named simply in relation to the points of the compass, were re-designated with titlesmore reflective of their regional characteristics, Hwaam-myeon (picturesque scenery of rocky mountain) and Yeoryang-myeon (surplus of food), Jeongseon County now features the four eups of Jeongseon, Gohan, Sabuk, and Sindong and five myeons of Hwaam, Nam, Yeoryang, Bukpyeong, and Imgye. These are administratively composed of 181 ris and 987 bans.
