901 NPA Split, Creating 731 NPA (Tennessee)

NPA 731 created from split of 901

Area code 731 was created in September 2001 from a geographic split of area code 901. The new code was assigned to western Tennessee, while 901 was retained for the Memphis metropolitan area.

NPA 731 split from 901 for most of West Tennessee

Area code 731 was assigned on September 17, 2001, to most of West Tennessee outside the immediate Memphis area. As a result, area code 901 was reduced to cover only Shelby, Fayette, Hardeman, and Tipton counties.

Permissive ten-digit dialing begins in 731

Permissive ten-digit dialing began on April 24, 2021, in area code 731. This allowed callers to use either seven or ten digits for local calls in preparation for the transition to mandatory ten-digit dialing due to the designation of 988 as a nationwide code for the National Suicide Prevention Lifeline.

Mandatory ten-digit dialing implemented in 731

Mandatory ten-digit dialing was implemented in area code 731 on October 24, 2021. This change was required to resolve conflicts with the new 988 code for the National Suicide Prevention Lifeline, ensuring all local calls used the full ten-digit number.
