319 Area Code in Iowa, United States
Description
Area code 319 serves southeastern Iowa, including cities like Cedar Rapids, Iowa City, Waterloo, and Burlington. It is one of the original area codes from 1947 and originally served a larger portion of the state before being split to create 563 in 2001. The 319 region includes major universities such as the University of Iowa and several hubs for manufacturing, healthcare, and education. Cedar Rapids, a key city in the area, is known for its food processing and strong cultural scene. Despite the split, 319 remains a core identifier for southeastern Iowa. It supports a dynamic mix of college towns, mid-sized cities, and rural communities.
