580 Area Code: Lawton, Oklahoma

Oklahoma's 580 area code covers the western and southern parts of the state outside the central Oklahoma City and northeastern Tulsa metros, with Lawton as the primary city. Lawton sits in southwestern Oklahoma immediately adjacent to Fort Sill, one of the largest Army installations in the country and home to the Field Artillery School. The military presence shapes a substantial slice of the local population and economic profile alongside a long-running role as the regional commercial center for southwestern Oklahoma. The 580 footprint extends through Enid, Ponca City, Ardmore, Altus, and the surrounding cluster of small cities and farming counties spread across western and southern Oklahoma.

Records linked to 580 numbers in the directory often include Oklahoma City and Tulsa — Oklahoma cities outside the 580 footprint. The pattern reflects standard public-record dynamics, with phone numbers porting across Oklahoma and addresses linked across multiple cities. The directory currently documents 399 distinct prefixes within 580 in detail, a working subset of the prefix population the code carries.

Lawton's median age sits well under the US figure, at the low thirties, a pattern shaped heavily by the substantial military and military-family population at Fort Sill. Median household income runs below the national reading, home values come in dramatically below the US median, and population places Lawton among the mid-sized Oklahoma cities — substantial enough to anchor a regional economy organized around the military installation, healthcare, and the surrounding agricultural counties. The broader 580 footprint reflects an unusually large geographic stretch of Oklahoma with a relatively dispersed population.
