Area code 743

Area code 743 serves North Carolina, including Greensboro, Winston-Salem and Burlington (Eastern time). It has been in service since May 23, 2016 and shares its area with 336.

Numbers starting with 743 drew 746 reports to the FTC from Aug 14, 2026 to Nov 11, 2026 and 209 complaints to the FCC since November 2023. The number on your screen can be faked, so a 743 number proves nothing about where a call came from.

Phone companies holding 743 exchanges

Each exchange (the three digits after the area code) is assigned to one carrier. 100% of these exchanges are pooled: their numbers are handed out in blocks of 1,000 to other carriers, so the holder below is not always the company serving a given number.
