The borders of this area ran from the southeastern protrusion of East Prussia (the Suwalki triangle) following the Neman River up to Mosty (excluding Grodno), including Volkovysk and Pruzhany up to the Bug River to the west of Brest-Litovsk and then following the border of the General Government to East Prussia.

Until the end of July 1941, Białystok was under the management of the military authorities, then it was subordinated to the civil administration.
Bialystok District was established on 1 August 1941; it was simultaneously excluded from the operational zones of the German Army in the Soviet Union.
From then until 1944, Gestapo and SS engaged in executions in the area, for example in the Nowosiółki forests near Choroszcz, where 4,000 people were executed.
At the same time, some small areas to the east of the 1939–1941 German-Soviet border were incorporated into the East Prussian district of Scharfenwiese (now Ostrołęka).
With this the city of Scharfenwiese henceforth held more hinterland to the east.

The center of administration for the district was the Polish city of Białystok.
The East Prussian Higher President and Gauleiter Erich Koch from Königsberg (modern-day Kaliningrad) was appointed Civilian Commissioner for the area, later Chief of Civil Administration (Chef-der-Zivilverwaltung).
