History of Area Code 641
Area code 641 entered service on July 9, 2000, as a geographic split from area code 515. The split assigned 641 to many communities outside the remaining 515 territory in central Iowa.
Iowa originally received area codes 319, 515, and 712 when the North American Numbering Plan began in 1947. Area code 641 was created as telephone use increased and the 515 region needed additional numbering resources. Area code 641 was created as a split, not as an overlay, and it remains a geographic area code.
