Regulatory Information and Historical Context
The North American Numbering Plan Administration (NANPA) regulates area code 580, managing telephone number assignment across the United States, Canada, and participating regions. NANPA created area code 580 on November 1, 1997 as a geographic split from area code 405 to accommodate growing demand for telephone numbers in Oklahoma.
Area code 405, one of the original area codes established in 1947, initially covered the entire state of Oklahoma. By 1997, population growth and increased telephone service adoption required the split, with 580 serving southwestern Oklahoma while 405 retained central Oklahoma (including Oklahoma City). Area code 405 later added overlay area code 572 to meet continued demand.
Current Status: Area code 580 currently has no overlay area codes. With 79.5% of available prefixes assigned as of 2025, the area code is not in jeopardy of exhaustion. Under current projections, 580 will remain stable in its current configuration until at least 2029.
This evolution shows how telecommunications infrastructure adapts to population growth and technology adoption.
