Coffs Harbour: landline numbers and carriers
Coffs Harbour is one of the town-level numbering areas the ACMA register uses under area code 02 (NSW & ACT). The register lists 66 number blocks for it with about 211,000 allocated numbers, held by 19 carriers. A landline that calls you from one of these blocks was issued for the Coffs Harbour area — though the line may since have been ported, and caller ID can be spoofed.
