US Area Code Lookup

Understanding US Area Codes

The North American Numbering Plan (NANP) divides the United States and its territories into geographic numbering plan areas (NPAs). Each area is assigned a three-digit area code. Knowing the area code can tell you the general location of a phone number, which is essential for businesses, marketing, and personal communication.

Why use an Area Code Lookup?
