Narrabri: landline numbers and carriers
Narrabri is one of the town-level numbering areas the ACMA register uses under area code 02 (NSW & ACT). The register lists 36 number blocks for it with about 38,000 allocated numbers, held by 17 carriers. A landline that calls you from one of these blocks was issued for the Narrabri area — though the line may since have been ported, and caller ID can be spoofed.
