Adelaide: landline numbers and carriers

Adelaide is one of the town-level numbering areas the ACMA register uses under area code 08 (SA, WA & NT). The register lists 279 number blocks for it with about 3.7m allocated numbers, held by 24 carriers and spread over the 08700…, 08709…, 08708…, 08707…, 08812…, 08816…, 08831…, 08842…, 08710…, 08711…, 08815…, 08720…, 08722…, 08732…, 08811…, 08844…, 08712…, 08713…, 08742…, 08813…, 08827…, 08817…, 08824…, 08836…, 08723…, 08810…, 08819…, 08830…, 08833…, 08835…, 08837…, 08839…, 08845…, 08715…, 08716…, 08733…, 08820…, 08821…, 08822…, 08843…, 08846…, 08847…, 08714…, 08717…, 08721…, 08747…, 08825…, 08829…, 08840…, 08744…, 08823…, 08826…, 08832…, 08834…, 08838…, 08841… and 08849… dialling prefixes. That makes Adelaide the 2nd largest of 640 numbering areas under 08 by block count, with 13.2% of the area code's allocated numbers. A landline that calls you from one of these blocks was issued for the Adelaide area — though the line may since have been ported, and caller ID can be spoofed.
