About 319 Area Code
Area code 319 serves Cedar Rapids, Iowa City, Waterloo and the east-central region of Iowa. Established in 1947 as one of the original 86 area codes in the North American Numbering Plan, 319 initially covered the entire eastern third of the state before a 2001 split created area code 563 for northeastern communities. Today, 319 spans major economic centers across Linn, Johnson, Black Hawk, and Des Moines counties. The code supports local voice and SMS-capable numbers used by manufacturers, universities, healthcare providers and retail operations across urban and rural markets.
The 319 region combines advanced manufacturing (aerospace electronics, bioprocessing, ag products), major education hubs (University of Iowa in Iowa City, colleges in Cedar Rapids and Waterloo), and healthcare networks. Cedar Rapids is a global leader in corn processing and produces over 540 million gallons of ethanol annually. Local businesses use 319 numbers for customer support, appointment scheduling, order confirmations, and field service dispatch. Using a local number typically delivers stronger pickup rates than toll-free alternatives because customers recognize the area code and trust the local connection.
