History

Original numbering plan areas and area codes of Minnesota in 1952

When the American Telephone and Telegraph Company (AT&T) created the first nationwide telephone numbering plan for Operator Toll Dialing in 1947 to automate and speed the connection of long-distance calls, the United States and Canada were divided into 86 geographic numbering plan areas (NPAs) and assigned the original North American area codes. Minnesota was divided into a south-eastern area including the Twin-Cities with area code 612 and the rest of the state in the south-west, north, and north-east with area code 218.[2] In 1954, the southern half of 612 was designated a separate numbering plan area with area code 507 as the third area code for the state.
