In Level Two, you can find the Auror Headquarters, the Misuse of Muggle Artifacts Office, and the Wizengamot Administrative Services.

Here, on Level Three, you can find the Accidental Magic Reversal Squad, the Obliviator Headquarters, and the Muggle-Worthy Excuse Committee.

Level Four has a long title and several smaller divisions. Here, you can find the Beast, Being and Spirit Division, the Goblin Liason Office, and the Pest Advisory Board.

On Level Five, you can find three major sections: the International Confederation of Wizards, British Seats; the International Magical Office of Law; the International Magical Trading Standards Body.

On Level Six, there are four major sections, each devoted to the problems and concerns inherent in magical transportation. You'll find the Apparition Test Center, the Broom Regulatory Control, the Floo Network Authority, and the Portkey Office.

This level is always a fun one, if extremely untidy. Here, you may find the British and Irish Quidditch League Headquarters, the Official Gobstones Club, and the Ludicrous Patents Office.

No one knows what lies behind these doors and unless you have specific business in these corridors, you'd best not enter.
