Willunga: landline numbers and carriers
Willunga is one of the town-level numbering areas the ACMA register uses under area code 08 (SA, WA & NT). The register lists 40 number blocks for it with about 46,200 allocated numbers, held by 20 carriers. A landline that calls you from one of these blocks was issued for the Willunga area — though the line may since have been ported, and caller ID can be spoofed.
