Kor Usilic existed as a planet found in the Kor Usilic system. This system resided in the Bootana Hutta area of Hutt Space. Specifically, it was positioned within the Outer Rim Territories section of Hutt Space, which itself was located in the Slice portion of the galaxy. Hyperlanes provided connections to both the Gos Hutta and Kor Hunamma systems.
The Usilic kajidic designated Kor Usilic as their throneworld.
The reference book The Essential Atlas, published in 2009 and authored by Jason Fry along with Daniel Wallace, provided the first textual reference to Kor Usilic, locating it within grid square S-11.
