580 Area Code: Location, Time Zone and Phone Lookup

580 is a unique area code in the United States. It is the only area code in the country that is divided between two time zones. The eastern half of the area code, which is located in Oklahoma, observes Central Time, while the western half, located in Texas, observes Mountain Time.The history of 580 is closely tied to the history of the time zones in the United States. The area code was created in 1947, when the country switched from a four-time zone system to a six-time zone system. At the time, the 580 area code encompassed the entire state of Oklahoma.

In 1995, the area code was split in two, as the western half of Oklahoma moved to the 405 area code. This created two separate time zones in the 580 area code. The eastern half of the area code continued to observe Central Time, while the western half began observing Mountain Time.

Today, the 580 area code is still divided between two time zones. The eastern half of the area code, which is located in Oklahoma, observes Central Time, while the western half, located in Texas, observes Mountain Time.
