FirstGroup operates the city buses under the name First Aberdeen, as the successor of Grampian Regional Transport (GRT) and Aberdeen Corporation Tramways. Aberdeen is the global headquarters of FirstGroup plc, having grown from the GRT Group. First is still based at the former Aberdeen Tramways depot on King Street, which has now been redeveloped into a new headquarters and bus depot. Stagecoach East Scotland also run buses in Aberdeen and Aberdeenshire, under the Stagecoach Bluebird brand. Megabus run buses from the bus station to places north and south of the city.
