Area code 901 is an area code in the U.S. state of Tennessee. Originally it was the area code for the entire state, but now it is limited to the southwest corner of the state, including the city of Memphis.

Under the original 1947 North American Numbering Plan, area code 901 covered the entire state of Tennessee.
In an area-code split that was a flash-cut sometime during 1954, area code 901 was restricted to West Tennessee; while the eastern two-thirds of Tennessee--essentially, the entire state east of the Tennessee River--were reassigned the 615 area code.
After an area-code split that became mandatory on September 17, 2001, area code 901 serves only Shelby and Tipton counties and portions of Fayette, Lauderdale and Hardeman counties, a district very roughly corresponding with the Tennessee portion of the Memphis metropolitan area. The remaining areas formerly served by 901 were reassigned the 731 area code.
