Redcliffe: landline numbers and carriers
Redcliffe is one of the town-level numbering areas the ACMA register uses under area code 07 (QLD). The register lists 70 number blocks for it with about 431,000 allocated numbers, held by 22 carriers. A landline that calls you from one of these blocks was issued for the Redcliffe area — though the line may since have been ported, and caller ID can be spoofed.
