The Department for the Regulation and Control of Magical Creatures is the second largest department of the Ministry of Magic (after the Department of Magical Law Enforcement), found on level four of the building. It deals with concealing magical creatures from Muggles, as well as the needs of those creatures and controlling them. They provide safe habitats for creatures and control the selling and breeding of them. In severe cases uncontrollable creatures can be executed and the Department of Magical Accidents and Catastrophies will provide Obliviators to aid in removing the memory of events from Muggles who may have seen.
It has three main divisions, established in 1811 by Grogan Stump, the Minister for Magic at the time. These are the Beast, Being, and Spirit Divisions. For a creature to qualify as a being they need to have sufficient intelligence to understand the laws of the magical community and to bear a part of the responsibility in shaping those laws. Those who class as spirits would fall under that category if it weren't for the fact that calling them 'beings' is inappropriate.
 Beast Division
Centaur Liason Office
Werewolf Registery and Werewolf Capture Unit
There is a debate as to which division werewolves should belong in. However the registery and Capture Unit are part of the Beast Division as they deal with the untamable side of werewolves.
 Being Division
Werewolf Support Services
This service is found in the Being Division as it deals with werewolves when they are in their human form and not dangerous.
 Spirit Division
The Spirit Division was created at the request of ghosts who felt that they were more 'has-beens' than 'beings'.
Ghoul Task Force
The Ghoul Task Force exists to remove ghouls from Muggle houses, however, in wizarding families ghouls present no trouble.
 Pest Sub-Division
This includes the Pest Advisory Burau. Members of this sub-division will help wizards rid themselves of troublesome pests.
 Goblin Liason Office
 Committee for the Disposal of Dangerous Creatures
 Ministry of Magic Classifications
To classify how dangerous a creature is, the Ministry of Magic has created five categories:
|XXXXX||Known wizard killer / impossible to train or domesticate|
|XXXX||Dangerous / requires specialist knowledge / skilled wizard may handle|
|XXX||Competant wizard should cope|
|XX||Harmless / may be domesticated|
