Area code 984 is an overlay for 919 in central North Carolina, covering the Research Triangle cities of Raleigh, Durham, Chapel Hill, and surrounding communities. Introduced in 2011, it was created to support the continued population and technological growth in the region. With ten-digit dialing now required, 984 is commonly assigned to new mobile phones, businesses, and residents. It complements the legacy 919 code and plays a key role in maintaining telecommunications access for one of the fastest-growing areas in the southeastern United States. 984 reflects the region’s ongoing expansion in education, technology, and innovation.
