History of Area Code 405
Area code 405 was established in 1947 as one of the original North American Numbering Plan area codes. It originally covered the entire state of Oklahoma.
In 1953, area code 918 was created for eastern Oklahoma, leaving 405 in western and central parts of the state. In 1997, area code 580 was split from 405 for much of western and southern Oklahoma. Area code 572 was added as an overlay to 405 in 2021, giving central Oklahoma an additional code without changing the geographic boundaries of the 405 region.
The splits and overlay reflected the need for more telephone numbers as residential, business, cellular, and other telephone services expanded. Existing 405 numbers remained in use after the 572 overlay was introduced.
