A Brief History of Area Code 919

Area code 919 was created in 1954 to serve the eastern half of North Carolina. In 1998, the eastern coastal counties split off into the new 252 code, confining 919 to the Triangle region. The 984 overlay was added in 2012, and 10-digit dialing became mandatory.

Numbers in the 919 area code use Eastern Time (ET). The region observes Daylight Saving Time, shifting from EST (UTC-5) to EDT (UTC-4) between March and November each year.

Best time to call: Standard business hours run 9:00 AM to 5:00 PM Eastern, Monday through Friday. Eastern Time matches New York and is three hours ahead of the West Coast, so late morning is usually a safe window from either coast.
