The Federal Office of Information, alternatively referred to as the Government Building, is a prominent government building in Hillwood.
The building's entrance has a Latin motto: "Cave, Quivi Sumus". This directly translates into "Beware, Whoever We Are".
Mr. Bailey works here as a department supervisor.
- Despite clearly being the same structure in its three appearances, the naming of the building is somewhat inconsistent. In both "Arnold's Christmas" and Hey Arnold! The Movie, it's referred to as "Federal Office of Information", but in "Save the Tree", this building is depicted as being "City Hall". However, in "Mr. Green Runs", when Arnold and Mr. Green attempt to appeal to Councilman Gladhand to fix the pothole on Vine Street, they visit a different building called "City Hall".
