The Administrative Registration Department was a department of the Ministry of Magic. It was probably a sub-division of another department, such as the Department of Magical Law Enforcement, and was responsible for the registration of the wizarding population. After the Fall of the Ministry of Magic the Muggle-Born Registration Commission was created under this department.
It is possible that once a witch or wizard had a child, they had to register the baby as a member of the magical community of Great Britain through this department.
