An area code is the first three digits of a standard 10-digit NANP telephone number. The technical term for an area code is a Numbering Plan Area (NPA) code.
Most US area codes identify a geographic area. However, some NPA codes are used for non-geographic services rather than a particular location. NANPA maintains separate lists for geographic and non-geographic area codes.
The state-by-state list is cross-checked against current area-code directory data, while NANPA remains the authoritative source for US number assignments.

US area codes are the 3-digit codes (NPA) that identify a specific geographic area within the North American Numbering Plan. They sit at the start of every 10-digit US phone number and tell the network where to route a call.
The area code is always the first three digits of a 10-digit US phone number, in the format NXX-NXX-XXXX. If you only have a partial number, a reverse phone lookup tool can help.
Every area code maps to a specific city, region, or state. Enter the 3-digit code into the search or area code lookup tool above to see the state, major cities, and time zone it covers.
The country code (+1) applies to the whole US, plus Canada and several Caribbean nations under the NANP. The area code is a smaller piece inside that system that narrows the number down to one region or city.
An overlay is when more than one area code serves the same geographic region, added when an area needs more numbers. Everyone keeps their existing number, but every call then needs the full 10 digits, even within the same area code.
New codes are created when a region is running out of number combinations, usually from rising demand for cell phones, VoIP, and business lines. Regulators respond with a split, a new code for part of the region, or an overlay, a second code layered on top.
