Introduction
The 743 area code went live across North Carolina's Piedmont Triad in 2015 to keep phone numbers flowing through Greensboro, Winston-Salem, and High Point.
Anyone opening a business, moving to the region, or fielding an unfamiliar call needs to understand what this prefix actually signals.
This guide covers where the 743 area code reaches, why regulators added it, how ten-digit dialing changed the region, and how to spot a spoofed call. By the end, you will know exactly how to claim a 743 phone number and put it to work with confidence.
- The 743 area code overlays 336 across the Piedmont Triad, so both codes now share the same North Carolina territory.
- Ten-digit dialing has been mandatory since April 2016, even for calls between neighbors in the same town.
- Every community under the 743 area code runs on Eastern time, matching the rest of North Carolina.
- A cloud phone platform can activate a 743 phone number in minutes, with no Piedmont Triad office required.
What the 743 Area Code Covers Across the Piedmont Triad
The 743 area code reaches Greensboro, Winston-Salem, and High Point, plus a wide stretch of small towns strung along the I-85 corridor.
It shares this exact footprint with the older 336 area code, since regulators stacked 743 on top instead of redrawing any boundary.
That means a caller in Winston-Salem and a caller in High Point can both carry a 743 number despite sitting on opposite ends of the Triad.
Greensboro, Winston-Salem, and the Towns Between Them
Greensboro anchors the eastern half of the coverage area as the region's largest city, while Winston-Salem holds down the western side around its downtown arts district. High Point fills the middle as the self-declared furniture capital of the world. Asheboro, Burlington, and Mount Airy round out the smaller communities that share this same three-digit prefix across north-central North Carolina, stretching well into both Randolph and Rockingham counties.
The 2015 Overlay That Ended Seven-Digit Dialing
Area code 336 went into service in 1997 after splitting away from the older 910 numbering plan that once stretched across a much larger slice of the state.
Growth across Greensboro, Winston-Salem, and High Point kept climbing through the 2000s and 2010s as new businesses and households claimed fresh lines.
By the mid-2010s, regulators recognized that another geographic split would force thousands of existing residents to swap their numbers.
Why Regulators Chose an Overlay Over a Split
Regulators activated the 743 area code on October 24, 2015, letting new numbers keep flowing without touching a single existing 336 customer. Permissive dialing ran through April 23, 2016, and mandatory ten-digit dialing began the very next day across the shared territory. The first new numbers reached customers that May, matching overlays already running in Charlotte and the Research Triangle.

Ten-Digit Dialing Rules for the Piedmont Triad
Because the 743 area code shares its territory with 336 instead of replacing it, every local call in the region requires all ten digits, including the area code.
Dialing just seven digits, a habit many longtime residents grew up with, has not worked anywhere in the overlay zone since April 2016.
That rule applies whether the person calling holds a 336 number or a 743 number, and no long-distance charges apply within the shared territory.
- Always dial the area code plus the seven-digit number, even for calls across the street
- Save new contacts with the full ten digits from the start
- Update saved speed-dial entries that only stored seven digits
- Expect the same ten-digit format on landlines, mobiles, and VoIP lines alike
How to Tell a Genuine 743 Call From a Scam
The 743 area code itself carries no risk on its own; real Piedmont Triad residents, hospitals, and small businesses use it every day.
Scammers know that a local-looking prefix earns instant trust, which is exactly why they spoof caller ID displays to make fraudulent calls seem like they are coming from a neighbor.
The digits on a screen never tell the whole story, and the caller's behavior is what actually matters.
Warning Signs Worth Hanging Up Over
According to the Federal Communications Commission, scammers routinely fake caller ID information to disguise where a call truly originates, so an area code alone can never confirm a caller's identity. Watch for urgent demands to pay a bill immediately, requests for gift cards or wire transfers, or callers claiming to represent a utility company while pushing for personal details. Hang up and dial the official number listed on a bill or website instead of trusting whatever showed up on the screen. A legitimate business will never pressure someone into paying instantly or sharing a one-time verification code over the phone.
What Time Zone Governs 743 Area Code Calls
Every community inside the 743 area code operates on Eastern time, observing daylight saving right alongside the rest of North Carolina.
That shared clock keeps scheduling simple for businesses, since a call placed at 9 a.m. in Greensboro lands at 9 a.m. in Winston-Salem without any conversion.
Companies coordinating appointments, deliveries, or support calls across the Triad never need to double-check a client's local hour before dialing.
“This is not a random string of digits — it is the Piedmont Triad's second calling identity, layered onto 336 to keep Greensboro, Winston-Salem, and High Point connected.”
The Local Advantage of a Matching Number
Businesses serving Greensboro, Winston-Salem, or High Point gain something real by matching their number to a prefix locals already recognize.
Callers answer faster, trust faster, and refer their neighbors faster once they see this area code on the screen instead of an unfamiliar toll-free line.
A 743 phone number tells a customer something simple right away: this business understands the Piedmont Triad and is easy to reach.
Local Number vs Toll-Free for Piedmont Businesses
A toll-free number still makes sense for national brands chasing recognition everywhere at once. A local number instead tells a caller in Burlington or Asheboro that the company on the other end is part of their own community, not a distant call center somewhere else. For local service businesses especially, that distinction often decides whether the phone gets answered at all, and pairing a local number with reliable VoIP service providers helps even a brand-new team sound like an established Piedmont Triad player. Understanding how the 336 area code shares this same territory helps residents make sense of who is really on the line.
