North American area codes

Every area code in the +1 numbering plan — 466 in all — with where it is, the cities it covers and its time zone. Pick a code to see its overlays and history, and to check a number from it for free.

New area codes coming

Scheduled by NANPA; existing numbers do not change.

United States

Area codes by state, with the main cities each one covers.

Canada

Area codes by province and territory.

US territories

Puerto Rico, the US Virgin Islands and the Pacific territories — domestic calls from the US.

Caribbean & Atlantic

Dialed like US numbers, billed as international. The codes one-ring scams favour.

Toll-free and special codes

Not tied to any place: the number could belong to a business anywhere in North America.

All area codes, in order

Every active and scheduled code, numerically.
