Find any 319- phone number in Iowa
The 319 area code covers the entire state of Iowa and was one of the original numbering plan area codes, assigned in 1947 after the North American Numbering Plan (NANP) was created. This plan was created by AT&T in order to have a system for efficient access to telephone services in the United States and Canada.
The 319 area code is also tied to some specialty services. It is often used for Test Numbers and for short code services. Short code services are used by organizations for text message and automated phone calls, for example. Iowa is the only state to use the 319 area code; other states are assigned area codes that are a three-digit combination of numbers.
