Canberra: landline numbers and carriers
Canberra is one of the town-level numbering areas the ACMA register uses under area code 02 (NSW & ACT). The register lists 195 number blocks for it with about 2.1m allocated numbers, held by 24 carriers. A landline that calls you from one of these blocks was issued for the Canberra area — though the line may since have been ported, and caller ID can be spoofed.
