Although Koyraboro Senni is associated with settled towns, it is a cosmopolitan language which has spread east and west of Gao, to the Fula people living at the Mali–Niger border and to the Bozo people of the Niger River.
The majority of speakers live in the Gao Region of Mali.
Nasalized realizations of vowel sounds may also occur, but they are rare among different dialects.
