History & Cultural Notes
Southern and western Oklahoma's economy runs on a mix of defense, agriculture, and energy. Lawton, the area's largest city, grew up around Fort Sill, a major U.S. Army post and home to the Field Artillery School, which has shaped the city since the early 1900s. Enid anchors the state's wheat industry with large grain storage and processing facilities, and Ardmore sits within the historic Ardmore Basin oil field, a legacy of Oklahoma's early-20th-century petroleum boom.
Key industries across the region include:
- Defense and aerospace, centered on Fort Sill
- Agriculture, particularly wheat and cattle
- Energy, including oil and gas
- Manufacturing
- Food and beverage processing
Area code 580 was created effective November 1, 1997, splitting off from area code 405 and taking most of southern and western Oklahoma—including Lawton, Enid, and Ardmore—while 405 kept the Oklahoma City metropolitan area; a permissive dialing period ran through April 1, 1998. The territory also stretches into the Oklahoma Panhandle, reaching Guymon and Boise City, among the most sparsely populated parts of the state, along with other served communities such as Ada, Ponca City, Duncan, and Altus.
