Cedar Rapids

Iowa City

Cedar Rapids is home to facilities for both Qauker Oats and General Mills, securing its position in the American food industry. The 319 area code covers both Cedar Rapids and Iowa City. Implemented in 1947, 319 is one of the original American area codes. Until the year 2000, it was able to successfully cover all of Iowa’s residents. However, in 2000 it was decided that an overlay was necessary for the region due to exhaustion of numbers under 319. The Cedar Rapids area code was not exhausted due to population growth, but rather due to the rapid expansion of cell phone lines and other forms of communication. Accordingly, many individuals in the Cedar Rapids and Iowa City area code had more than one phone number, which was too much for area code 319 to support.
