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.

Frequently asked questions

Do overlays and new splits appear immediately?
The quiz uses a curated teaching set. For the latest assignment charts, check NANPA or the US5 area-codes directory.
How is scoring calculated?
Most quizzes award one point per correct round. Your results panel shows correct answers over total rounds, plus an emoji grid you can share.
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.
