Area code 743 is a key telecommunications designation within the United States, specifically serving the state of North Carolina. Below are several important aspects of this area code: Geographic Location and Service Area: Area code 743 is assigned to North Carolina, serving most of the north-central and northwestern parts of the state. This includes the Piedmont Triad region and parts of the northern Foothills and Mountains. The area code covers 60 cities, including prominent ones like Greensboro, High Point, Burlington, Salisbury, and Asheboro, and extends over 18 counties such as Guilford, Forsyth, Davidson, Randolph, and Alamance​​​​​​. Implementation and Overlay with Area Code 336: The 743 area code was assigned on August 13th, 2014, and became operational on May 23rd, 2016. It was created from the 336 area code through a split or overlay process, indicating that it shares the same geographical region as the 336 area code. This overlay necessitates a 10-digit dialing pattern for local calls within the same area code​​​​. Time Zone and Largest City Served: Located in the Eastern Standard Time (EST) zone, area code 743 observes Daylight Saving Time, which involves clock adjustments in spring and autumn. The largest city served by this area code is Greensboro, a major urban center in North Carolina​​. In summary, area code 743 plays a vital role in the telecommunications infrastructure of North Carolina, particularly in the north-central and northwestern regions, including the economically and culturally significant Piedmont Triad area. Its overlay with area code 336 and coverage of numerous cities and counties make it an integral part of the state's communication network.
