On December 14, 2009, Malheur Bell was merged into its corporate parent, Qwest Corporation and the use of the Bell logo was discontinued.

BellSouth also operated in the Australian and New Zealand market.

BellSouth operated in New Zealand under the name of BellSouth New Zealand Limited from 1993 until 1998 when it was acquired by Vodafone. It competed against Telecom New Zealand. Its operations in Australia were under the name of BellSouth Australia Pty Limited.
