Tiaro: landline numbers and carriers
Tiaro is one of the town-level numbering areas the ACMA register uses under area code 07 (QLD). The register lists 30 number blocks for it with about 38,000 allocated numbers, held by 19 carriers. A landline that calls you from one of these blocks was issued for the Tiaro area — though the line may since have been ported, and caller ID can be spoofed.
