Area code 810 is a telephone area code in the North American Numbering Plan for the east-central part in the U.S. state of Michigan. The numbering plan area (NPA) comprises the cities of Flint, Lapeer, Port Huron, and the southern portion of the Thumb. ===Prior usage of 810 for TWX=== In 1962, AT&T assigned area code 510, then designated as a Service Access Code (SAC) of the format N10, for conversion to dial service of the Teletypewriter Exchange Service (TWX) in the United States. Later in the decade, additional area codes, including 810 were assigned. NPA 810 served a large area from Michigan southward to all of the southern and southeastern United States. Telex use of the area code was decommissioned in 1981 after conversion of the service to new transmission technologies by Western Union. ==Service area== The numbering plan area includes all of Genesee and Lapeer counties and portions of Oakland, Macomb, St. Clair, Sanilac and Livingston counties.
