810

Area code 810 is a telephone area code in the North American Numbering Plan, specifically serving the east-central part of the U.S. state of Michigan. Geographic Coverage: Area code 810 covers the east-central part of Michigan, including cities like Flint, Lapeer, Port Huron, and the southern portion of the Thumb area. This makes it a vital part of the state's telecommunication infrastructure, connecting various communities within this region​​. Establishment and Origin: The area code 810 was assigned for use in Michigan on December 1, 1993, and it originated from a split of the 313 area code. This split was part of the process to meet the growing demand for phone numbers in the region. The assignment of area code 810 reflects the expansion and development of telecommunication services in Michigan​​​​. Time Zone and Dialing Pattern: Located in the Eastern Standard Time (EST) zone, area code 810 observes Daylight Saving Time, which involves clock adjustments in spring and autumn. The standard dialing pattern for local calls within the same NPA (Numbering Plan Area) in the 810 area code is seven digits​​. In summary, area code 810 is essential for telecommunications in east-central Michigan, encompassing several major cities and counties. Its implementation in 1993 and its designation to serve areas outside the Detroit metropolitan area underscore its significance in the region's communication network. The area code's location in the Eastern Time Zone and adherence to Daylight Saving Time are also important operational aspects.
