The North American Numbering Plan is a system used by the United States and Canada to assign telephone numbers to various geographic areas. This system was introduced in 1947, and is made up of number plan areas (NPAs), central office codes (CO codes), and exchange codes. NPAs are easy to identify as they are the first three digits that make up a telephone number. The plan assigns a unique area code to each region, allowing for easy local calling. It also helps service providers to sort and distribute telephone services more efficiently. The 484 area code is used to designate the geographic region in eastern Pennsylvania.
