Area code 901 was one of theoriginal North American area codes created in 1947 for the first nationwidetelephone numbering plan. It served the entire state of Tennessee until 1954, when the state was divided in aflash cut into two numbering plan areas.West Tennessee retained the area code, while the eastern two-thirds of the state, essentially, the part of the state east of theTennessee River, receivedarea code 615.
Despite the presence of Memphis, the state's largest city at the time,West Tennessee is not as densely populated as the state's other twoGrand Divisions. As a result, while the eastern two-thirds of the state went from one area code to four from 1995 to 1999, 901 remained the sole area code for West Tennessee for 47 years. However, by the turn of the millennium, 901 was close to exhaustion due to the Memphis area's rapid growth, as well as the proliferation of cell phones and pagers. On September 17, 2001,area code 731 was assigned to most of West Tennessee outside the immediate Memphis area. Area code 901 remained in service forFayette,Hardeman,Shelby,Tipton counties, an area largely coextensive with the inner ring of the Memphis area.
Despite the Memphis area's growth and the continued demand for telecommunication services, 901 is not in danger of exhaustion. According to 2021 projections, relief will not be required until about 2035.[1] It is one of the few urban area codes that have not beenoverlaid, making Memphis one of the largest cities where seven-digit dialing is still possible.
The area code was the inspiration for the name ofMemphis 901 FC, a local professional soccer team that plays in theUSL Championship.[2]
