The capital of Sarir was the city of Humraj, tentatively identified with the modern-day village Khunzakh. The king resided in a remote fortress at the top of a mountain.
Sarir bordered the Khazars to the north, the Durdzuks to the west and northwest, the Georgians and Derbent to the south. As the state was Christian, Arab historians erroneously viewed it as a dependency of the Byzantine Empire.
