The digit  indicates the state or territory, generally followed by two letters on AM and three on FM. Stations with call-signs beginning in 2 are based in New South Wales or the ACT, 3 in Victoria, 4 in Queensland, 5 in South Australia, 6 in Western Australia, 7 in Tasmania, and 8 in the Northern Territory  .
