About Area Code Maps
Area code maps show the geographic boundaries of each three-digit area code in the North American Numbering Plan (NANP). Unlike some countries where area codes cover precisely defined regions, NANP area codes can cover entire states, parts of states, or even overlap with each other.
In many urban areas, overlay codes have been introduced where multiple area codes serve the same geographic region. For example, New York City has area codes 212, 332, 347, 646, and 929 all serving the same area. This means a geographic map alone doesn't tell the complete story.
Use our area code lookup to find specific details about any area code, or browse the full list.
