336 Area Code: North Carolina Location, Cities & Scam Guide (2026)

What Is the 336 Area Code?

The 336 area code serves north-central and northwestern North Carolina, covering the Piedmont Triad region. This includes major cities like Greensboro, Winston-Salem, and High Point, along with portions of the northern Foothills and Blue Ridge Mountain communities.

Created in 1997 when it split from area code 910, the 336 area code now serves approximately 1.6 to 1.8 million residents across one of North Carolina's most economically significant regions. The Piedmont Triad is the state's third-largest metropolitan area, after Charlotte and the Research Triangle.

If you're receiving calls from 336 numbers or considering a North Carolina phone number, here's what you need to know.

The History of the 336 Area Code

Understanding the 336 area code means understanding North Carolina's rapid telecommunications growth in the 1990s.

Before 1997: The 910 Era

Prior to the split, area code 910 covered a massive portion of North Carolina, including the Piedmont Triad, the Sandhills, and the Southeastern coast. This vast territory became unsustainable as phone number demand exploded.

December 15, 1997: The Birth of 336

On December 15, 1997, area code 336 was created in a geographic split from 910. The new code took over the northern portion of the former 910 territory, while 910 retained the Fayetteville and coastal areas.

This split was part of a nationwide wave of new area codes—336 was one of 43 area codes introduced in 1997 alone, as the telecom industry struggled to keep up with cellular phone growth.

2014-2016: The 743 Overlay

By 2014, even the 336 area code was running low on available numbers. On August 20, 2014, the North Carolina Utilities Commission announced that 336 would receive an overlay: area code 743.

The transition timeline:

• October 24, 2015: Permissive 10-digit dialing begins
• April 23, 2016: Mandatory 10-digit dialing takes effect
• May 2016: First 743 numbers issued

Today, both 336 and 743 serve the same geographic area. You must dial all 10 digits for local calls.

336 Area Code Time Zone

The 336 area code operates in the Eastern Time Zone (ET):

• Standard Time: UTC-5 (Eastern Standard Time/EST)
• Daylight Saving Time: UTC-4 (Eastern Daylight Time/EDT)

When planning calls to or from 336 numbers, keep these time differences in mind:

North Carolina observes Daylight Saving Time, so the offset changes in spring and fall.

Common Scam Types from 336

Health Insurance Scams Callers claim to offer Affordable Care Act plans, Medicare supplements, or other coverage. They're often phishing for personal information.

Auto Warranty Scams The persistent "your car's warranty is about to expire" robocall that plagues every area code.

IRS/Tax Scams Callers claim you owe back taxes or that there's an issue with your return. Real IRS contacts come by mail first.

Utility Scams Fraudsters claim to be from Duke Energy or Piedmont Natural Gas, threatening disconnection unless immediate payment is made.

Tech Support Scams Callers claim your computer has a virus and offer to "fix" it for a fee while actually installing malware.

How to Protect Yourself

1. Don't trust caller ID — Numbers can be spoofed to show any 336 number
2. Never share sensitive information — Real businesses don't cold-call asking for SSN or payments
3. Hang up and call back — If a call seems legitimate, look up the official number yourself
4. Use call blocking apps — Nomorobo, Hiya, or Truecaller can filter known scam numbers
5. Register with Do Not Call — Visit donotcall.gov
6. Report scam calls — File complaints at reportfraud.ftc.gov or ncdoj.gov
