Geelong: landline numbers and carriers
Geelong is one of the town-level numbering areas the ACMA register uses under area code 03 (VIC & TAS). The register lists 100 number blocks for it with about 572,900 allocated numbers, held by 23 carriers. A landline that calls you from one of these blocks was issued for the Geelong area — though the line may since have been ported, and caller ID can be spoofed.
