Buffalo: landline numbers and carriers
Buffalo is one of the town-level numbering areas the ACMA register uses under area code 03 (VIC & TAS). The register lists 27 number blocks for it with about 39,000 allocated numbers, held by 18 carriers. A landline that calls you from one of these blocks was issued for the Buffalo area — though the line may since have been ported, and caller ID can be spoofed.
