I believe the numbers are the official numbers but the area has been "privatised" and the numbers are now "meaningless" in a way that the houses are renumbered as "K<num>" and all their internal maps use these. The lift gate is "open" for walk or bike so it could be easily mapped by a local hero.
Probably the lift gates and the area limit shall be surveyed as well, and the reception offices. I believe (right now) the area is open in the direction of Crvenog gloga.
