Introduction
The 743 area code serves northwestern North Carolina as an overlay of the established 336 area code. Introduced in 2017 by NANPA to address number exhaustion in the 336 region, 743 covers the same geographic territory as 336 — a densely populated corridor of the Piedmont Triad that includes Greensboro, Winston-Salem, and High Point.
An overlay code means two area codes share the same geographic area. Both 743 and 336 numbers ring at addresses throughout the same cities and counties in northwestern North Carolina.
This guide covers what the 743 area code is, which cities and counties it covers, how it relates to 336, the time zone it operates in, and how businesses can get a 743 area code number.

Learn moreWhat Is the 743 Area Code?
The 743 area code is an overlay for the 336 area code region in northwestern North Carolina. An overlay is a type of area code assignment used when a geographic region has exhausted — or is approaching exhaustion of — available number combinations in its original area code.
NANPA approved 743 as the overlay for 336 with the code becoming active for new number assignments starting in 2017.
An important practical implication of overlay codes: because two codes share the same geographic area, 10-digit dialing is required for all local calls. Callers in Greensboro must dial all 10 digits — including the area code — even for local calls within the same city.
Cities and Counties in the 743 Area Code
The 743 area code covers the same territory as 336 — the Piedmont Triad region and surrounding areas of northwestern North Carolina.

743 vs 336: What Is the Difference?
The practical difference between a 743 number and a 336 number is none — both reach the same geographic area, both are assigned to lines physically located in northwestern North Carolina, and both require 10-digit dialing for local calls within the region.
336 has been the area code for northwestern NC since 1993, when it was split off from the original 919 statewide code. It is far more widely recognized by residents of the region. 743 numbers are newer and were assigned to new lines beginning in 2017.

How to Get a 743 Area Code Number

Dialing a 743 Number from Abroad
Reaching a Piedmont Triad line from outside the United States works the same way as calling any US number: the caller dials the international exit code used in their own country, then the US country code 1, then the full ten-digit number. The overlay changes nothing about international dialing — 743 and 336 lines are reached identically.
- From most of Europe, Africa, and Asia: 00 + 1 + 743 + the seven-digit number
- From any mobile phone worldwide: + 1 743 555 0123 — the plus sign replaces the exit code
- From Canada and other NANP countries: dial 1 + 743 + the number, exactly as a domestic US call
Triad manufacturers and universities field regular overseas calls, so many publish their numbers in full international format. Callers abroad should also account for Eastern Time when scheduling — mid-afternoon in Europe reaches Greensboro at the start of its business morning. For more, see 743 area code.
Porting a Number Into or Out of the Triad Region
Businesses in Greensboro, Winston-Salem, or High Point that switch phone providers can keep their existing digits. US portability rules oblige the current carrier to release a number once a verified transfer request is submitted, and the process applies equally to overlay and legacy prefixes, landlines, mobiles, and cloud lines.
- 1Gather the account number, service address on record, and any transfer PIN from the current carrier.
- 2Submit the port order through the new provider, which manages the exchange between carriers.
- 3Keep the existing service active until the port completes to avoid losing the number.
Routine transfers usually finish within a few business days. A company moving away from North Carolina can port its Triad digits to a cloud platform and continue answering the same number from any location.
Choosing Between Local and Toll-Free for Triad Businesses
Companies serving the Piedmont Triad often weigh local digits against a toll-free line. Each sends a different signal, and the better choice follows from where the customers are.
- Local digits suit businesses winning customers inside the region — furniture showrooms, medical practices, contractors — because residents answer familiar prefixes more readily
- Toll-free numbers suit operations fielding callers from across the country, such as a manufacturer's national order desk or support line
- Running both is common: local digits for community-facing marketing, a toll-free line for nationwide service
Cloud phone platforms make the pairing simple, routing both numbers to the same team and devices. The decision is about presentation, not infrastructure — either type of number can ring anywhere the business works.
Conclusion
The 743 area code is the 2017 overlay for northwestern North Carolina's 336 region, covering the Piedmont Triad cities of Greensboro, Winston-Salem, and High Point. It operates in the Eastern Time Zone and requires 10-digit dialing throughout the region.
For businesses serving or targeting customers in the Triad region, a 743 or 336 local number is a straightforward way to establish familiarity with North Carolina customers. Explore number availability at meratalk.com.
