The metropolitan see is located in Hulwan, and suffragan dioceses include Hamadan ( the diocese is often referred to as Beth Madaye), Masabadan, Dinawar and Nihawand. The area of the metropolitan province is relatively large, with most of the Christians located in the south.

Province of Rai
The metropolitan province of Rai (1) encompasses also the areas of the central Iranian plateau, mainly by its suffragan dioceses of Ispahan and Kirman. The latter two have been detatched from their original province (Beth Parsaye and Khuzestan) under the Seljuks, who also separated the the province of Tabarestan from Rai

Province of Tabarestan
The rather small metropolitan province of Tabarestan was detatched from Rai relatively recently under the Seljuks. The seat of the province is Astarabad in Gorgan, and suffragan dioceses had been established in Mazandaran and Gilan. However, the central and western parts of the Caspian shore appear to have very few to no new converts.

Province of Herat
The province of Herat used to be part of the province of Merv; its suffragan dioceses are Merv-i-Rud, Pusang, Badisi and Qadistan, Segestan and Farrah. The vast southern expanses of the province are effectively mission territory, populated mostly by Manicheans and Buddhists.

The city of Samarqand had become a major centre of Christianity in Sogdia, and its metropolitan province extends well along the entirety of the Oxus valley. Suffragan dioceses include Amul, Bokhara, Arbinjan, Nasaf, Faryab, Balkh and Tukharistan. The region of Khwarezm on the lower Oxus is part of the diocese of Bokhara; and Buddhist-majority Tukharistan also has only one diocese. In the area, Nestorian faith is intertwined with Manichean and Buddhist influences.
