The northern part was returned to Hungary by the annexation of the remainder of Carpathian Ruthenia after Czechoslovakia ceased to exist in 1939, however the redeemed territories of the former county remained separate from the administrative branch office of Máramaros. After the Second Vienna Award, the rest of the county became part of Hungary as well and Máramaros County was recreated on this territory, with Máramarossziget as capital. Afterwards, the northern part of Máramaros county along with the administrative branch offices of Máramaros became part of the Soviet Union, Ukrainian SSR, Zakarpattia Oblast. Since 1991, when the Soviet Union split up, the Zakarpattya region is part of Ukraine.
