In Sumuri District of Teluk Bintuni Regency, Sumuri people reside in Tofoi (district capital), Materabu Jaya, Forada, Agoda, Saengga, Tanah Merah Baru, Onar Lama, and Onar Baru villages.

The following basic vocabulary words are from Voorhoeve (1975),[4] as cited in the Trans-New Guinea database:[5]
