Geographic Coverage & Major Cities
Area code 743 covers the Piedmont Triad and north-central North Carolina, including Guilford, Forsyth, Alamance, and neighboring counties. Because it is an overlay, it shares the identical footprint of the 336 area code rather than covering a separate zone.
- Greensboro – the largest city in the Triad
- Winston-Salem – home of Wake Forest University
- High Point – the furniture capital
- Burlington & Mount Airy – established Triad communities
As a newer code over the Triad, 743 numbers are common among lines set up after the original 336 numbers grew scarce.
A Brief History of Area Code 743
Area code 743 was activated in 2012 as an all-services overlay on the 336 region. The 336 code itself split from 910 in 1997. An overlay adds a second area code across the same geographic area, so existing 336 customers kept their numbers while new lines could be assigned either code, under mandatory 10-digit dialing. A further overlay, 472, was later assigned to the same region.

Numbers in the 743 area code use Eastern Time (ET). The region observes Daylight Saving Time, shifting from EST (UTC-5) to EDT (UTC-4) between March and November each year.
