In 1993 Southwestern Bell Corp. moved its headquarters to San Antonio, Texas and, during its annual meeting of stockholders in 1995, the company announced that its name would be changed to SBC Communications, Inc. The name change was an effort to reinforce the company's national and global reach and the company not only stated that "SBC" wasn't an acronym for Southwestern Bell Corporation, but that it did not stand for anything at all.

SBC then proceeded (as permitted by the Telecommunications Act of 1996) to acquire fellow baby bell Pacific Telesis, the Regional Bell operating company serving Nevada and California, in 1997 and the former independent Bell System franchise SNET (Southern New England Telephone).

SBC then announced plans to acquire Ameritech, the Regional Bell operating company serving Illinois, Indiana, Michigan, Ohio, and Wisconsin,, and told the FCC that it would allow competitors access to local markets where it had had a monopoly if the FCC would allow them to acquire Ameritech. The FCC agreed and in May 1998, SBC and Ameritech announced the merger would move forward. After making several organizational changes (such as the sale of Ameritech Wireless to GTE) to satisfy state and Federal regulators, the two merged on October 8, 1999. The FCC later fined SBC Communications $6 million for failure to comply with agreements made in order to secure approval of the merger.
