From missed calls to compliance checks — area code lookup solves a surprisingly wide range of everyday problems.

Large states have dozens of codes. Use the tool above to look up a code in the table.
Area codes were invented in 1947 under the North American Numbering Plan (NANP) to route long-distance calls without operators. Over 75 years later, they still tell you exactly where a number originated.
The North American Numbering Plan (NANP) governs area codes across the US, Canada, and 18 Caribbean territories. All share the +1 country code but are split into hundreds of unique 3-digit area codes.
Every US and Canadian phone number starts with a 3-digit area code (NPA) after the +1. That code was originally assigned to a specific geographic region — a state, a province, or a major metro.
When a region exhausts available numbers, a new area code (an "overlay") is added to the same geography. Today, New York City alone uses over 10 area codes — 212, 332, 347, 646, 718, 917, 929, and more.
