History of Area Code 515
Area code 515 is one of the original North American area codes created in 1947. It originally covered a much larger part of Iowa than it does today. The North American Numbering Plan assigned these first area codes to organize long-distance telephone service across the United States and Canada.
Area code 515 was reduced by later splits as telephone demand grew. In 1954, Iowa created area code 319 from part of 515. In 2001, another split created area code 641, which took many communities in central and southern Iowa, while 515 remained in the north-central part of the state, including Des Moines and Ames. As of now, area code 515 does not use an overlay.
