The area code 804 is located in Virginia and covers the Richmond Metropolitan Area, including Richmond, Tuckahoe, and Mechanicsville. It also encompasses the Northern Neck and Middle Peninsula. The area code was first put in service on June 24, 1973, and was split in 1996 and 2001 to create area codes 757 and 434, respectively. The 804 area code is predicted to run out of central office prefixes in the third quarter of 2024, and the State Corporation Commission (SCC) has approved the new area code 686 to be implemented after the numbers in area code 804 have been exhausted.
