Area code 580 serves southwestern and southern Oklahoma, including cities such as Lawton, Enid, Altus, and Ardmore. It was created in 1997 from a split of the 405 area code to better serve the rural and smaller metropolitan areas of the state. The 580 region is known for agriculture, military installations like Fort Sill, and natural resources. It spans a large geographic area with a relatively low population density, making it a critical part of Oklahoma’s communication infrastructure. 580 remains a standalone area code and symbolizes the state’s rural resilience and close-knit communities.
