01 — Oklahoma at a Glance
Oklahoma, by the numbers.
Area code 405 covered all of Oklahoma from 1947. On January 1, 1953, northeastern Oklahoma, including Tulsa, split off into 918, though 405 kept most of the state's phone lines.
That arrangement held 44 years. On November 1, 1997, 405 shrank again to central Oklahoma around Oklahoma City, while the southern and western portions became 580.
Rather than split further as cell phone use grew, Oklahoma added overlay code 539 in 2011 over 918's Tulsa-area territory.
Today 405 (plus its overlay) serves greater Oklahoma City, 918/539 serve Tulsa and the east, and 580 covers the rural west and south.
Did you know?
Oklahoma's 918 area code, created in 1953 to relieve the original 405, held its territory unchanged for over half a century before finally needing its own overlay, 539, in 2011.
