Rockingham: landline numbers and carriers
Rockingham is one of the town-level numbering areas the ACMA register uses under area code 08 (SA, WA & NT). The register lists 65 number blocks for it with about 206,000 allocated numbers, held by 18 carriers. A landline that calls you from one of these blocks was issued for the Rockingham area — though the line may since have been ported, and caller ID can be spoofed.
