Southwestern Bell Telephone Company, LLC is a wholly owned subsidiary of AT&T. It does business as other d.b.a. names in its operating region, which includes Arkansas, Kansas, Missouri, Oklahoma, Texas, and portions of Illinois. The company is currently headquartered in Dallas, Texas at One AT&T Plaza.
In 1984, the former AT&T agreed to divest its local telephone operations but retain its long distance, R&D and manufacturing arms. From this, SBC Communications Inc. (first known as Southwestern Bell Corp.) was born. Twelve years later, the Telecommunications Act of 1996 drove major changes in the competitive landscape.
Following a 1995 name-change to SBC Communications, the company combined its Southwestern Bell Telecom division, which provided telephone equipment, with Southwestern Bell Telephone Co. as a cost-saving measure.
