BellSouth Corporation is asking federal regulators for permission to sell long-distance service in Mississippi, Alabama, Kentucky and the Carolinas.
The company already has been approved by the Federal Communications Commission to offer the service in Georgia and Louisiana, which it began selling May 24th.
The Alabama Public Service Commission approved BellSouth's request on May 28th.
BellSouth said the application covers 8.2 million customer lines, or about a third of its network.
The FCC has until September 18th to vote on the company's application.
BellSouth is the third of the nation's four dominant regional Bells to enter the long-distance market under terms outlined by the 1996 law allowing local phone companies to enter the market.
