Area code 712 covers western Iowa, including cities such as Sioux City, Council Bluffs, and Spencer. It is one of the original area codes assigned in 1947 and continues to serve a large, primarily rural portion of the state. Known for its agricultural output, small-town communities, and scenic views along the Missouri River, the region maintains a steady pace of life and close-knit community values. The 712 area code remains untouched by overlays, allowing for seven-digit local dialing. It serves as a long-standing symbol of western Iowa’s consistency, tradition, and connection to the land.
