336 Area Code: Greensboro, North Carolina

North-central North Carolina is served by the 336 area code, with Greensboro as the primary city. Greensboro sits in the rolling Piedmont country of central North Carolina, on a stretch of land that has long supported a substantial textile and furniture-manufacturing base — the broader Piedmont Triad region (Greensboro, Winston-Salem, High Point) anchored much of the country's furniture industry through the twentieth century. The local working economy reflects healthcare, several university campuses (UNC Greensboro and North Carolina A&T among them), and a growing logistics and aerospace sector. The 336 footprint extends through Winston-Salem, High Point, Burlington, and the surrounding Piedmont counties.

In records the directory has compiled for 336 numbers, other North Carolina cities — Asheville, Charlotte, Fayetteville, and Greenville — recur frequently. None of those are inside the 336 footprint. The pattern reflects standard public-record dynamics, with phone numbers porting across North Carolina and addresses linked across multiple cities. The directory currently documents 666 distinct prefixes within 336 in detail, a working subset of the prefix population the code carries.

Greensboro's home values come in below the US median, with median household income running below the national figure. The city's median age sits a few years under the US reading, and population places Greensboro among the larger cities in North Carolina — substantial enough to anchor its share of the broader Piedmont Triad region. The 336 footprint as a whole reflects a long-running mix of mid-sized cities, university towns, and the surrounding rural counties of north-central North Carolina.
