Mackay: landline numbers and carriers
Mackay is one of the town-level numbering areas the ACMA register uses under area code 07 (QLD). The register lists 101 number blocks for it with about 288,000 allocated numbers, held by 19 carriers. A landline that calls you from one of these blocks was issued for the Mackay area — though the line may since have been ported, and caller ID can be spoofed.
