Australia Postal Codes

Australia Postal Codes are four-digit numbers used to identify specific geographic areas for efficient mail sorting and delivery. The postal code system is structured so that the first digit typically represents the state or territory, with the remaining digits further identifying regions, cities, suburbs, or specific areas. For example, Sydney, in New South Wales, has postal codes ranging from 2000 to 2299, depending on the suburb. The system ensures precise mail delivery across Australia's vast and diverse regions, including remote and rural areas.
