Introduction
The 919 area code is synonymous with North Carolina's Research Triangle — the innovation hub anchored by Raleigh, Durham, and Chapel Hill. Home to three world-class research universities (NC State, Duke, and UNC-Chapel Hill) and Research Triangle Park (RTP), one of the largest research parks in the world, the 919 area code has become one of the most recognised prefixes in the US tech and life sciences industry.
The Raleigh-Durham metro has ranked among the fastest-growing large metros in the US for over a decade, consistently drawing corporate relocations, biotech investment, and tech talent. This guide covers where the 919 area code applies, which cities and ZIP codes it serves, its time zone, history, and how businesses secure a 919 number today.

History of the 919 Area Code
The 919 area code has a long history that reflects North Carolina's transformation from a tobacco-and-textiles economy to one of the most dynamic tech and biotech clusters in the country.
- 1954: 919 assigned to all of North Carolina (a single statewide code).
- 1993: 704 expanded; 910 split from 919 for southeastern NC (Wilmington, Fayetteville); 336 split for the Piedmont Triad (Greensboro, Winston-Salem, High Point).
- 1998: 919 reduced to Wake, Durham, Orange, Johnston, and Chatham counties.
- 2011: 984 introduced as overlay for 919 as Research Triangle growth depleted available numbers.
- 2011–present: 919 and 984 co-exist as overlays serving the same Research Triangle geography.
The speed at which 919 required an overlay — driven by Research Triangle Park expansion and Raleigh's rapid corporate in-migration — reflects how quickly North Carolina's innovation economy grew in the 2000s.

Scam Awareness: 919 Area Code Calls
The 919 area code is spoofed by scammers who want calls to appear local to Raleigh or Durham. Common impersonation targets include Duke Energy, Wake County government, the NC Department of Revenue, and local healthcare systems.
- Duke Energy never threatens immediate disconnection without prior written notice — hang up on any such call
- NC government agencies contact residents by mail first; calls demanding immediate tax payment are scams
- Never provide personal or financial information to an unsolicited 919 caller
- Report suspicious calls to the FCC at fcc.gov/consumers and the NC Attorney General at ncdoj.gov

As the home of Research Triangle Park, Duke University, UNC, and NC State, 919 is one of the most credible tech and life sciences area codes in the Southeast.
