Part of the Shinile Zone, available maps disagree on its exact location: according to the OCHA map for the Somali Region, Erer is bordered on the south by the Oromia Region, on the southwest by Afdem, on the west by the Afar Region, on the north by Djibouti, on the northeast by Ayesha, on the east by Shinile and the southeast by the territory of Dire Dawa; however, the map of the Oromia Region published by Disaster Prevention and Disaster Agency shows that the western part is separated into its own woreda called Afdem, and the woreda the OCHA map identifies as Afdem should be named Mieso.
