Its original name upon founding was State Telephone Company of Texas. It later changed its name to Southwestern Associated Telephone Company, and General Telephone Company of the Southwest.
In 1996, Contel of New Mexico and Contel of Texas were merged into GTE Southwest.
In 2000, Bell Atlantic purchased GTE and renamed itself Verizon. Shortly thereafter, the pending sale of GTE Southwest's operations to Valor Telecom was completed. GTE Southwest's Arkansas operations in Arkansas, Missouri, and Oklahoma were sold to CenturyTel to become CenturyTel of Northwest Arkansas (GTE's operations in Arkansas were completely sold off). GTE Southwest retained its name and operations in more populated areas of Texas.
GTE Southwest is the only former GTE operating company that has not changed its official legal name under Verizon ownership.
