History of Area Code 405

When the Federal Communications Commission (FCC) decided to make phone numbers public in the USA in 1947, area code 405 was introduced to serve the demand of the entire Oklahoma state. It was one of the original 85 area codes, initially implemented to serve telephone demand nationwide.

After over half a century of service, the 405 was split in 1997 by adding the new area code 580. However, within two decades, phone number usage exceeded that, leading to adding the new area code 572 as an overlay to 405.

Overall, Oklahoma has 5 area codes.
