Southwestern Bell Telephone Company is a subsidiary of AT&T. The business it holds is similar to AT&T Southwest as well as other DBA names along its working district. The company’s present headquarter is in One AT&T Plaza, Dallas, Texas.

In 1882, Missouri and Kansas Telephone Company were officially instituted. It was merged with one administrating unit of Bell System together with Southwestern Telegraph and Telephone Company in Texas-Arkansas, Bell Telephone Company in Missouri known also as Missouri Bell Telephone Company during March 1, 1912 and Pioneer Telephone and Telegraph Company in Oklahoma.

The last 3 corporations were officially consolidated into the Missouri and Kansas Telephone Company during 1920 and were renamed as Southwestern Bell Telephone Company. This company was usually regarded the initial move of AT&T corporate ladder prior the 1984 disintegration of the company. While being a branch of Bell System, it was the largest Bell Operating Company of 22 owned AT&T.

Subsequent to the disintegration of AT&T, the Southwestern Bell Telephone Company was administered by the Southwestern Bell Corporation. Ironically it was the smallest of the entire 7 “Baby Bells” for holding a single telephone company. Both holding companies were frequently referred “Southwestern Bell”. During 1995, SBC chose to switch its business name to SBC Communications, Inc which is now called AT&T to transform into a national telecommunications corporation. The change was made possible by Telecommunications Act of 1996. The SBC gathered Pacific Telesis Group during 1997, the Southern New England Telecommunications during 1998 and the Ameritech during 1999.

During December 30, 2001, the pioneer Southwestern Bell Telephone Company integrated in Missouri closed down when it amalgamated with Southwestern Bell Texas, Inc and individual administrating company. At this time, previous assets of the 1882 instituted company were moved to a corporation established on that day which is the Southwestern Bell Telephone, LP in Texas. This business discontinued operating during June 29, 2007 when all its asses were combined into SWBT Inc in Missouri established 8 days before. Just then, SWBT Inc obtained the previously latent name of Southwestern Bell Telephone Company.

From the change of name during 1920 until 1999, the SWVT was trademarked as Southwestern Bell. During 1999, SBC Communications started to link its business name to the brands of Bell Operating Companies they hold. This modification effected Southwestern Bell logo to be pursued with a divider line of SBC Global Network surrounded with a circle including Pacific Telesis “access” symbol.

In 2000, Bell logo was slumped from the symbol of Southwestern Bell. During 2001, SBC regulated its administrating business branding logos and put SBC company logo northwest of the brand “Southwestern Bell” and was recognized as the SBC Southwestern Bell. The brand disappeared in 2002 when the SBC dropped the brands of the entire administrating corporations to utilize “SBC” as a countrywide name. Since DBA names were not accepted until the start of 2003, Southwestern Bell Telephone Company brand stayed on the phone book covers released during December 2002 as well as January 2003.

After the DBA names were accepted, SBC started to formally employ Southwestern Bell Telephone, LP brand.
