What time zone is 534 area code in the USA?

The 534 area code is situated in the Central Time Zone (CT) of the United States. This time zone observes Daylight Saving Time, shifting from Central Standard Time (CST) to Central Daylight Time (CDT) during the warmer months. The National Institute of Standards and Technology provides precise timekeeping and updates on time zone changes.

History of the 534 Area Code

The 534 area code was introduced as an overlay to the 715 area code in 2010. This change was implemented to address the growing demand for new telephone numbers in the region. Overlays are a common solution to number exhaustion, allowing existing numbers to remain unchanged while providing additional numbering resources. The North American Numbering Plan Administrator (NANPA) manages the allocation and administration of area codes across North America.
