What is an Australia Postal Code?
An Australian postal code (commonly called a postcode) is a four-digit number used by Australia Post to identify geographic regions for mail delivery. Each state and territory is assigned specific postcode ranges to ensure accurate routing.
Examples:
- New South Wales (NSW): 1000–2999
- Victoria (VIC): 3000–3999
- Queensland (QLD): 4000–4999
- Western Australia (WA): 6000–6999
Our generator follows these official postcode ranges to ensure every generated result is realistic and structurally valid.
