History of the 336 Area Code
- 1947: all of North Carolina is in 704.
- 1954: the eastern and central part of the state becomes 919.
- 1993: 910 is split from 919. At first it includes the Triad.
- December 15, 1997: the Triad and the northwest are split from 910 and become 336. The 910 code had filled up in only about three years.

Three Codes in Five Years
People in Greensboro and Winston-Salem changed area codes twice in the 1990s: from 919 to 910 in 1993, and from 910 to 336 in 1997. That history is one reason the state chose an overlay in 2016 instead of another split. The Triad is known for furniture, textiles, trucking and several universities, and all of them place calls from 336 and 743 numbers.
How to Dial a 336 Number
Because more than one area code can serve the same streets, always dial the full ten-digit number.
- From the US or Canada: 1 + 336 + the seven-digit number
- From another country: your exit code + 1 + 336 + the seven-digit number
Is a Call From 336 a Scam?
A 336 number usually belongs to a local resident, a college or a regional employer. Fake calls about jury duty, utility bills and package deliveries are the common unwanted calls.
Watch for these warning signs:
- A recorded voice that says an account is locked or suspended
- A caller who wants payment by gift card, wire transfer or crypto
- A text with a link about a delivery, a toll or a refund
- A request for a one-time code that was just sent to your phone
Caller ID can be spoofed, so the number on your screen does not prove where a call comes from.
What to do with an unknown 336 call
- Let unknown numbers go to voicemail. A real caller leaves a message.
- Look up the company and call the number on its website.
- Block the number on your phone.
- Report scam calls at reportfraud.ftc.gov and register at donotcall.gov.
- Forward spam texts to 7726 (SPAM).
