Area Code 743 Location

Area code 743 serves Greensboro and the wider Piedmont Triad in north-central North Carolina. It’s an overlay for long-standing area code 336, created to add more phone number capacity as the region grows. The overlay means 743 and 336 cover the same places, including busy business districts, universities, and major travel routes. Greensboro anchors the area, with Winston-Salem and High Point forming a key urban triangle.

Major cities and communities in the 336/743 overlay include:

• Greensboro
• Winston-Salem
• High Point
• Burlington
• Kernersville
• Asheboro
• Lexington
• Thomasville
• Mount Airy
• Reidsville

Landmarks in the 743 area include Piedmont Triad International Airport (GSO), the Greensboro Coliseum Complex, and historic Old Salem in Winston-Salem. The region also hosts the High Point furniture market, a major event for home furnishings. Colleges and universities such as UNC Greensboro, Wake Forest University, and High Point University add to the area’s cultural and economic impact.

Introduced in 2016, area code 743 requires 10-digit dialing for local calls across the 336/743 territory. Existing 336 numbers stayed the same, while new numbers may be assigned with the 743 or 336 code. This overlay approach avoided splitting cities or changing familiar phone numbers. If a call shows a 743 phone number, it most likely comes from Greensboro or nearby Triad communities in north-central North Carolina.
