Mount Wilson: landline numbers and carriers
Mount Wilson 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 41,000 allocated numbers, held by 18 carriers. A landline that calls you from one of these blocks was issued for the Mount Wilson area — though the line may since have been ported, and caller ID can be spoofed.
