Wikipedia tells us; "Telephone administrations that manage telecommunication infrastructure of extended size, such as a large country, often divide the territory into geographic areas. This benefits independent management by administrative or historical subdivisions, such as states and provinces, of the territory or country. Each area of subdivision is identified in the numbering plan with a routing code. This concept was first developed in the planning for a nationwide numbering plan for Operator Toll Dialing and Direct Distance Dialing (DDD) in the Bell System in the United States in the 1940s, a system that resulted in the North American Numbering Plan for World Zone 1. AT&T divided the United States and Canada into numbering plan areas (NPAs), and assigned to each NPA a unique three-digit prefix, the numbering plan area code, which became known in short-form as NPA code or simply area code. The area code is prefixed to each telephone number issued in its service area."

Someone decided that this needed to celebrated.
