History of Area Code 580
Area code 580 was created on November 1, 1997, in a split from area code 405. The split happened because growing demand for phone numbers made the old 405 region too large to manage under one code. After the split, 405 stayed with Oklahoma City and nearby central Oklahoma, while 580 took most of the rest of the state outside the Tulsa area.
Area code 580 is a split area code, not an overlay. In 2021, the Oklahoma Corporation Commission approved an overlay for the same region, area code 572. Area code 572 officially overlaid 580 on May 24, 2021, and 10-digit dialing became necessary in the region.
