Abstract: Embodiments of the present application provide a method, an apparatus, a device, and a storage medium for judging permanent area change, and relate to the field of computer technologies. By determining feature information corresponding to at least one candidate user, where any candidate user is a user whose permanent area changes with a probability greater than a first preset probability threshold, and furthermore, by inputting feature information corresponding to the above-mentioned at least one candidate user into a preset classification model, it can be judged whether a target permanent area of the above-mentioned at least one candidate user is changed.
