641 Area Code in Iowa, United States

Area code 641 covers central and south-central Iowa, including cities such as Mason City, Ottumwa, Newton, and Indianola. It was created in 2000 from a split of area code 515 due to population growth and increasing telecommunications demand. The region is largely rural, with agriculture playing a central role in the local economy. It also includes several small colleges and community-focused towns. 641 remains a standalone area code with no overlays, and seven-digit dialing is still possible in some parts. The code represents the quieter, more traditional communities of Iowa’s interior, reflecting the state’s agricultural and civic roots.
