What time zone is 580 area code in the USA?

The 580 area code is situated in the Central Time Zone (CT) of the United States. This time zone observes Daylight Saving Time, meaning clocks are set forward by one hour in the spring and set back by one hour in the fall. This adjustment helps to make better use of daylight during the longer days of summer. For accurate timekeeping, you can refer to the National Institute of Standards and Technology.

History of the 580 Area Code

The 580 area code was created in 1997 as a result of a split from the original 405 area code. This change was necessitated by the growing demand for telephone numbers in the region, driven by population growth and the increasing use of telecommunications technology. The split allowed for a more efficient allocation of numbers and helped to accommodate the expanding needs of residents and businesses in the area. For more information on the history and administration of area codes, you can visit the North American Numbering Plan Administrator (NANPA).
