It serves Raleigh, Durham, Chapel Hill, Cary, and most of central North Carolina, and is a local (non-toll-free) area code in the Eastern Time Zone.
919 originally covered all of central and eastern North Carolina. The 1998 split (252) carved out the eastern part of the state, leaving 919 with the Triangle region. As Research Triangle Park's tech and biotech sectors grew, overlay 984 was added in 2011 to handle continued demand. Despite the overlay, a 919 number remains the heritage signal for established Triangle tech companies, biotech firms, and the area's three major research universities (Duke, UNC, NC State).
