 When in 1993 the new province Sa Kaeo was created, the district became the capital district of the province and was therefore renamed Mueang Sa Kaeo.The district is divided into eight sub-districts ("tambons"), which are further subdivided into 124 villages ("mubans").Sa Kaeo itself has town status ("thesaban mueang") and covers parts of "tambons" Sa Kaeo and Tha Kasem.
