Melbourne: landline numbers and carriers
Melbourne is one of the town-level numbering areas the ACMA register uses under area code 03 (VIC & TAS). The register lists 706 number blocks for it with about 10.5m allocated numbers, held by 31 carriers. A landline that calls you from one of these blocks was issued for the Melbourne area — though the line may since have been ported, and caller ID can be spoofed.

Worth knowing
