The diocese is the basic church body that comprises all the parishes of a determined geographical area. It is governed by the Diocesan Bishop, with the assistance of a Diocesan Assembly and a Diocesan Council. The OCA is currently composed of twelve geographic and three ethnic dioceses (Albanian, Bulgarian, and Romanian). The boundaries of the ethnic dioceses overlap those of certain geographic ones. These dioceses are the result of smaller ethnic jurisdictions joining the OCA at some point in its history, usually after having broken from other bodies. Dioceses are established by the Holy Synod whenever needed, and the Synod may also modify the boundaries of an existing diocese.
