Colane: landline numbers and carriers
Colane is one of the town-level numbering areas the ACMA register uses under area code 02 (NSW & ACT). The register lists 29 number blocks for it with about 14,900 allocated numbers, held by 17 carriers. A landline that calls you from one of these blocks was issued for the Colane area — though the line may since have been ported, and caller ID can be spoofed.
