Quick answer: Area code 743 is a telephone overlay covering North Carolina's Piedmont Triad — sharing the exact same territory as area code 336. Activated on May 23, 2016, it serves Greensboro, Winston-Salem, and High Point across twelve north-central North Carolina counties. The territory operates in the Eastern Time Zone, and ten-digit dialing has been mandatory since April 23, 2016.
What area code 743 covers across the Piedmont Triad
Area code 743 does not mark out its own territory — it is layered directly on top of the region already served by 336. Both codes cover the exact same footprint: the Piedmont Triad and portions of the northern Foothills and Mountains of North Carolina.
This all-services overlay means new phone numbers issued anywhere in the region can carry a 336 or 743 prefix, regardless of which one a caller's neighbor happens to have. No existing number changed when 743 launched — it simply expanded the pool of numbers available as the Triad's manufacturing, healthcare, and logistics economy kept growing.
Pairing a 743 number with a 624 area code Buffalo, New York presence creates a natural legacy-manufacturing-to-healthcare corridor, connecting the Piedmont Triad's furniture, textile, and freight economy with Buffalo's own university-and-medical-campus-anchored revival.

Greensboro, Winston-Salem, and the cities sharing a 743 number

The 743 territory spans twelve counties across north-central North Carolina, anchored by the three cities that give the Piedmont Triad its name.
The Triad's core cities:
- Greensboro (Guilford County) — The largest city in the territory, home to a major logistics hub and two significant universities
- Winston-Salem (Forsyth County) — Anchored by Wake Forest University and a leading academic medical center
- High Point (Guilford/Randolph/Davidson counties) — The global capital of the furniture industry, home to the twice-yearly High Point Market
Surrounding communities:
- Burlington (Alamance County) and Kernersville (Forsyth/Guilford/Davidson) — Established commercial and residential centers between the core cities
- Asheboro (Randolph County) — Anchoring the southern edge of the territory
- Reidsville (Rockingham County) and Eden (Rockingham County) — Communities along the northern Foothills approach
| Sub-region | Key communities |
|---|---|
| Guilford County | Greensboro, High Point, Kernersville |
| Forsyth County | Winston-Salem, Kernersville |
| Randolph & Davidson | High Point, Asheboro, Lexington, Thomasville |
| Outer counties | Burlington, Reidsville, Eden, Mount Airy |
From 910 to 336 to 743: North Carolina's Piedmont Triad numbering story

Area code 910 originally covered a broad swath of south-central and western North Carolina. As the state's population grew, area code 336 split off on December 15, 1997, to serve the Piedmont Triad region on its own — Greensboro, Winston-Salem, High Point, and the surrounding counties.
By the early 2010s, growth across the Triad's healthcare, logistics, and manufacturing sectors was pushing 336 toward exhaustion. Rather than force another disruptive split, the North Carolina Utilities Commission approved an overlay.
Permissive dialing for area code 743 began on October 24, 2015, ten-digit dialing became mandatory on April 23, 2016, and the new code officially entered service on May 23, 2016 — the 388th area code activated in North America.
| Milestone | Detail |
|---|---|
| Pre-1997 | Area code 910 covers a broad swath of south-central and western NC |
| December 15, 1997 | Area code 336 splits off for the Piedmont Triad |
| October 24, 2015 | Permissive dialing for 743 begins |
| April 23, 2016 | Ten-digit dialing becomes mandatory |
| May 23, 2016 | Area code 743 officially enters service |

Ten-digit dialing across the 336 and 743 territory
Because two area codes share one territory, every call placed within the region — even between two phones in the same Greensboro neighborhood — must include the area code.
| Calling scenario | Format |
|---|---|
| Any local call within the 336/743 territory | 743-XXX-XXXX (ten digits mandatory) |
| Anywhere else in the US or Canada | 1-743-XXX-XXXX |
| International call to a 743 number | +1 743 XXX XXXX |
Time zone: The entire 743 territory observes Eastern Time — the same zone as Charlotte, Raleigh, and Washington DC. Businesses coordinating between the Triad's three core cities never need to account for a time difference within the region.
Why Piedmont Triad businesses choose a 743 number

A 743 area code number places a business inside one of the Southeast's most established manufacturing, healthcare, and logistics economies.
Key reasons to establish a 743 area code number:
- High Point Furniture Market — The world's largest furniture industry trade event, held twice a year, anchors a deep home-furnishings design, manufacturing, and wholesale economy across the Triad
- Wake Forest University and Atrium Health Wake Forest Baptist — A top-ranked research university and its academic medical center anchor Winston-Salem's healthcare, biotech, and higher-education economy
- Piedmont Triad International Airport logistics hub — A major FedEx Ground and Air hub, alongside Old Dominion Freight Line's national headquarters in Thomasville, anchors a substantial freight and logistics sector
- UNC Greensboro and NC A&T State University — Two major public universities, including the nation's largest historically Black university, feed a steady pipeline of business, engineering, and STEM talent
- UCaaS virtual Piedmont Triad presence — Businesses targeting the Triad's furniture, healthcare, or logistics markets from outside North Carolina can establish immediate local credibility through a Unified Communications as a Service (UCaaS) platform, provisioning a 743 number with cloud-hosted voice, video, messaging, and analytics routed to any device worldwide; pairing a 743 number with a 618 area code Southern Illinois presence creates a natural logistics-and-manufacturing corridor connecting two regional freight and industrial hubs
Medicare fraud and other 743 area code scam calls

Area code 743 is a legitimate telephone prefix serving the Piedmont Triad's residents and businesses — but North Carolina ranks among the top five states nationally for unwanted call complaints, and scammers actively spoof 743 numbers to appear local.
Most frequently reported 743 scam types:
- Medicare and prescription fraud — The single most reported scam category nationally, with calls offering fraudulent insurance enrollment or discount medications, often targeting seniors across the Triad's retirement communities
- Government agency impersonation — Callers pose as the IRS, Social Security Administration, or Medicare, threatening legal action or benefit suspension unless personal information or payment is provided immediately
- Debt reduction robocalls — Prerecorded calls offering to erase credit card or loan debt in exchange for upfront fees
- Home improvement and utility scams — Unsolicited offers for repairs, solar panels, or energy assistance that request upfront payment for services never delivered
Staying protected: No legitimate government agency, Medicare representative, or utility company demands immediate payment over an unsolicited call. Report suspected 743 scam calls to the FTC at reportfraud.ftc.gov and to the North Carolina Attorney General's office.

Frequently asked questions
What is the 743 area code?
Area code 743 is a telephone overlay code serving North Carolina's Piedmont Triad, covering Greensboro, Winston-Salem, High Point, and the surrounding twelve counties. Activated on May 23, 2016, it shares the exact same territory as area code 336, meaning new numbers issued anywhere in the region can carry either prefix.
Where is the 743 area code located?
Area code 743 covers north-central North Carolina, including Guilford, Forsyth, Randolph, Davidson, Alamance, and Rockingham counties, along with portions of the northern Foothills and Mountains. Major cities include Greensboro, Winston-Salem, High Point, Burlington, and Kernersville.
Is 743 the same as the 336 area code?
Not exactly the same code, but the same territory. Area code 743 is an overlay, meaning it covers the identical geographic footprint as 336 rather than a separate region. A 743 number is just as local to Greensboro and Winston-Salem as a 336 number.
When was the 743 area code created?
Area code 743 was activated on May 23, 2016. It followed area code 336, which split off from area code 910 on December 15, 1997, to serve the Piedmont Triad region. Permissive dialing for 743 began in October 2015, and ten-digit dialing became mandatory across the shared territory in April 2016.
What time zone is the 743 area code in?
Area code 743 is in the Eastern Time Zone. The entire territory observes Eastern Standard Time (UTC−5) in winter and Eastern Daylight Time (UTC−4) during daylight saving time, the same zone as Charlotte, Raleigh, and Washington DC.
Why does the Piedmont Triad have two area codes?
The Piedmont Triad shares two overlapping area codes, 336 and 743, because regulators chose an overlay over another geographic split to relieve number exhaustion. Adding a new overlay code preserved existing phone numbers for residents and businesses rather than forcing a disruptive second split of the region.
Can I get a 743 number for a business outside North Carolina?
Yes. Virtual phone providers and UCaaS platforms offer 743 area code numbers to businesses and individuals regardless of physical location. A virtual 743 number establishes authentic Piedmont Triad presence, routes all calls to any device anywhere in the world, and connects your business with the region's furniture, healthcare, and logistics markets without a physical North Carolina office.
Is the 743 area code associated with scam calls?
Area code 743 is a legitimate telephone prefix for the Piedmont Triad, but North Carolina ranks among the top states nationally for unwanted call complaints, and scammers actively spoof 743 numbers to appear local. The most heavily reported fraud types include Medicare and prescription fraud, government agency impersonation, debt reduction robocalls, and home improvement scams. Any unsolicited call demanding immediate payment or personal information is a scam regardless of caller ID.
