712 Area Code in Iowa, United States
Description
Area code 712 serves western Iowa, including cities such as Sioux City, Council Bluffs, Carroll, and Storm Lake. It is one of the original area codes created in 1947 and has retained its boundaries for decades. The region is primarily rural, with a strong agricultural base and a scattering of small urban centers. 712 covers the Iowa side of the Omaha–Council Bluffs metropolitan area, playing a key role in regional commerce and connectivity. It remains a single-code region with no overlays and supports a mix of farming, industry, and local businesses. The 712 code is a longstanding symbol of Iowa’s western heartland and community resilience.
