Area code 984 is an overlay for 919 in central North Carolina, covering Raleigh, Durham, Chapel Hill, and nearby areas in the Research Triangle. Activated in 2011, it was introduced to accommodate the region’s explosive growth in technology, healthcare, and education. Ten-digit dialing is required. Though newer than 919, area code 984 is an essential part of the Triangle’s modern infrastructure and continues to grow with the influx of new residents, businesses, and academic institutions fueling the area’s innovation.
