Parramatta: landline numbers and carriers
Parramatta is one of the town-level numbering areas the ACMA register uses under area code 02 (NSW & ACT). The register lists 150 number blocks for it with about 1.4m allocated numbers, held by 24 carriers. A landline that calls you from one of these blocks was issued for the Parramatta area — though the line may since have been ported, and caller ID can be spoofed.
