A method ascertains a tolerance location which differs from a target location for a pickup point for an object which is at rest in an installation and which is intended to be picked up by a means of transport. An identification mark is put onto the object in a known relative position in relation to the pickup point. A computation device uses a locating apparatus arranged in the installation to ascertain a physical location of the identification mark in the installation. The computation device ascertains the tolerance location from the physical location and the relative position. A corresponding apparatus contains a corresponding identification mark and a corresponding computation device.
