The Werewolf Register was created by Newt Scamander in 1947. The Register was a list of all known werewolves in Great Britain, and was controlled and maintained by the Werewolf Registry sub-department of the Department for the Regulation and Control of Magical Creatures. It is unknown what happened to those who refused to register and were discovered later. However, the register was poorly kept, as Fenrir Greyback, a werewolf, managed to hide his status at first when he was brought up to the Ministry by pretending to be a Muggle tramp.
