Missouri Area Code
Missouri's area codes are numerical designations used in telecommunications to define specific geographic regions for phone numbering. As of my last update in September 2021, some notable area codes in Missouri include 314, which covers St. Louis, 636, serving parts of eastern Missouri, 573 for central and southeastern regions, and 417 for southwestern Missouri. These area codes help organize telephone communication within the state. Please verify with up-to-date sources, as area codes can change over time.

What time zone is Missouri?
Missouri is generally in the Central Time Zone (CT). The entire state follows Central Standard Time (CST), which is UTC-6, during the standard time of the year. However, during daylight saving time, Missouri observes Central Daylight Time (CDT), which is UTC-5. Daylight saving time in Missouri typically begins on the second Sunday in March and ends on the first Sunday in November, when clocks are set forward by one hour to observe CDT.
Note that the start and end dates of daylight saving time can change
Mississippi's area code history traces back to 1947 when the state introduced Area Code 601, covering the entire state. As population growth and telecommunications demands increased, Mississippi later added Area Code 228, serving the Gulf Coast region, in 1997. These area codes have efficiently managed phone numbering within the state, facilitating communication for its residents and businesses.
