Key Takeaways

• The 743 area code is an overlay for the Piedmont Triad region of north-central North Carolina.
• It was activated on April 1, 2015, as an overlay on top of the existing 336 area code.
• The entire 743 region observes Eastern Time — EST (UTC−5) in winter and EDT (UTC−4) in summer.

• You can get a local Greensboro number in minutes through a VoIP provider — no North Carolina address required.

What Is the 743 Area Code?

The 743 area code is a North American Numbering Plan (NANP) telephone prefix that serves north-central North Carolina, a region known as the Piedmont Triad. It is an overlay code, meaning it covers the exact same geographic area as the older 336 code rather than carving out a new region of its own.

The 743 code was introduced to keep pace with steady growth across the Triad's three anchor cities and their surrounding counties. Because it shares territory with 336, a new local number here is fully tied to Greensboro — residents and businesses treat both codes as one and the same.

For callers, businesses, and anyone searching for a regional number, the 743 offers a fresh supply of local Piedmont Triad numbers in a market where 336 numbers have grown harder to find.

Coverage Area and Geography

The 743 area code covers the entire Piedmont Triad region of north-central North Carolina. This includes Guilford, Forsyth, and Randolph counties, along with a wide ring of surrounding communities across more than a dozen counties.

Because 743 is an overlay, its boundaries mirror those of the 336 code exactly. The region sits between the Charlotte metro to the southwest and the Research Triangle to the east, forming the central pillar of North Carolina's economy.

For businesses using virtual numbers to reach the Piedmont Triad market, a 743 prefix signals immediate local relevance to customers, suppliers, and business partners throughout the region.

Major Cities in the 743 Region

Several cities define the identity of the 743 area code territory:

• Greensboro — the largest city in the region and the third-largest in North Carolina
• Winston-Salem — a historic city known for its tobacco, banking, and healthcare legacy
• High Point — the "Furniture Capital of the World," host to a major global furniture market
• Burlington — a growing city in Alamance County east of Greensboro
• Kernersville — a fast-expanding town at the heart of the Triad
• Asheboro — the Randolph County seat, home to the North Carolina Zoo
• Thomasville — a historic furniture town just south of High Point

Together these cities make the Piedmont Triad one of North Carolina's most important economic regions, blending manufacturing heritage with modern industry across many sectors.

Time Zone for the 743 Region

Every community in the 743 area code region observes Eastern Time. From early November through mid-March, the region runs on Eastern Standard Time (EST) at UTC−5. For the rest of the year it shifts to Eastern Daylight Time (EDT) at UTC−4.

For teams scheduling calls with 743 contacts, here are the key time conversions:

• 9:00 AM EST = 8:00 AM CST (Central time winter hours)
• 9:00 AM EST = 6:00 AM PST (West Coast winter hours)
• 9:00 AM EST = 2:00 PM GMT (UK standard time)
• 9:00 AM EDT = 1:00 PM GMT (UK during summer)

North Carolina observes Daylight Saving Time in line with federal rules. Clocks spring forward on the second Sunday in March and fall back on the first Sunday in November. Because the whole region shares a single time zone, there is no ambiguity when scheduling calls across the Piedmont Triad.

History of the 743 Code

An Overlay on the 336 Code

The 743 area code was activated on April 1, 2015, as an overlay on the existing 336 code. Rather than splitting the Piedmont Triad into two geographic zones, regulators chose an overlay so no resident or business would have to change an existing number. This approach has become the modern standard for adding numbers to growing regions.

The 336 code itself was created in 1997, when it split from the older 910 code covering much of central and eastern North Carolina. As the Triad's population and business base expanded, the supply of available 336 numbers ran low — prompting the 743 overlay.

Why an Overlay Instead of a Split

Overlays let a region add millions of fresh numbers without disrupting existing service. Everyone keeps their current number, and only 10-digit dialing becomes mandatory. The Triad followed the same overlay path taken by the 726 area code in San Antonio, reflecting a nationwide shift away from disruptive geographic splits.

How to Dial a 743 Phone Number

Dialing a 743 phone number follows the standard 10-digit format required across the United States. Because 743 overlays 336, 10-digit dialing has been mandatory in the Piedmont Triad since the overlay took effect. According to FCC dialing rules, every domestic call must include the full area code plus the 7-digit local number.

• From within the US: Dial 1 + 743 + 7-digit local number
• From Canada: Dial 1 + 743 + 7-digit number
• From outside North America: Dial your exit code + 1 + 743 + 7-digit number

Most smartphones auto-format calls correctly when a contact is saved with the full number. If you are calling from a landline, always include the 1 prefix for any call originating outside the 743 region.
