Azkaban is Unplottable.
Unplottability refers to the deliberate concealment of several areas around the world. Unplottable locations are either magically hidden from plain sight or simply removed on maps. Common reasons for unplottability are for individual safety and the protection of certain secrets, particularly within the schools of wizardry.
