How to play
Match NANPA area codes to the places they commonly identify. Area codes overlay the map differently from ZIP or county lines — a third coordinate system Americans use every day on phone numbers.
Area codes as regional shorthand
212 still signals historic Manhattan prestige in culture; 310 and 818 split Los Angeles basins; 305 points to Miami. Overlays and splits change over time, so treat quiz pairs as educational snapshots.
US5 also maintains `/area-codes` reference pages when you want the directory view instead of a scored round.

Is this official government data?
No. Games are educational practice tools. For decision data — cost of living, salary, ZIP demographics — use US5 Places, Cost, and Money pages, which cite Census / HUD-style sources.
