How North American area codes work
A North American phone number follows the pattern (NPA) NXX-XXXX. The first three digits — the NPA, or “number plan area” — are what everyone calls the area code, and they anchor a number to a geographic region across the US, Canada and much of the Caribbean.
The first codes were assigned in 1947. As phones, faxes, modems and mobiles multiplied, regions ran short of numbers. Early on, a crowded region was “split” into a new code; today new demand is almost always met with an overlay — a second code laid over the same map, which is why so many places now require ten-digit dialing.
Toll-free codes (800, 833, 844, 855, 866, 877, 888) aren’t tied to any city, and caller ID can be faked, so a familiar-looking area code never proves where a call truly came from. Each code page here spells out what to trust.
