About AT&T’s Corporate Office

Since its establishment in 1878, AT&T has moved its corporate office three times. It initially started operations in San Antonio but announced the relocation of the corporate office to One AT&T Plaza in Dallas, Texas, on June 27, 2008.

The company stated that it relocated to have better access to its clients and operations across the globe, to important technology associates, distributors, innovation, and human capital as it continues to expand locally and globally.

Previously in 1992, AT&T Inc. moved its corporate office from St. Louis, Missouri to San Antonio when it was still known as Southwestern Bell Corporation. San Antonio still hosts the Telecom Operations section of the corporation serving domestic and regional customer bases in different states in the U. S.

However, AT&T Mobility’s headquarters remains in Atlanta, Georgia, with buildings in Redmond, Washington, formerly the host of AT&T Wireless. Bedminster, New Jersey, is the base of the corporation’s Global Business Services division, the AT&T Labs, and the original AT&T Corp.

Also, St. Louis still houses AT&T Advertising Solutions, the corporation’s Directory operations.

  1. Names and addresses for ongoing problems should be included on all AT&T sites. I have spent hours on the phone with assistors getting no help or worse trying to sell me something. That is insulting.
