Area code 743 is an overlay for 336, covering the Piedmont Triad region of North Carolina, which includes Greensboro, Winston-Salem, and High Point. Introduced in 2016 to provide additional numbering capacity, it supports a region known for its furniture manufacturing legacy, higher education institutions, and growing business climate. Ten-digit dialing is mandatory. While 336 remains the more established code, 743 is essential to the Triad’s continued expansion and modernization. The area code reflects the region’s blend of Southern tradition and economic evolution.
