The largest telephone numbering plan in North American is the North American Numbering Plan (NANP), serving 25 regions or countries. Other countries maintain an autonomous numbering plan with distinct country codes within the international E.164 specifications by the International Telecommunication Union.
Each NPA was identified by a three-digit area code used as a prefix to each local telephone number. The United States received seventy-seven area codes, and Canada nine. The initial system of numbering plan areas and area codes was expanded rapidly during the ensuing decades, and established the North American Numbering Plan (NANP).
The second area code, 202, was assigned to the District of Columbia. The allocation of area codes was readjusted as early as 1948 before the implementation of the plan commenced. For example, the Indiana numbering plan area 317 was divided, which essentially provided a larger numbering pool in the Indiana suburbs of Chicago (area code 219).
