What is the Australia Postcode Finder?
This is a free tool for finding Australian postcodes. Search a suburb or town to get its 4-digit postcode, or enter a postcode to see every suburb that uses it. It covers all eight states and territories, from New South Wales to the Northern Territory.
It helps with online shopping, parcel delivery, visa and migration forms, job and university applications, and any website or form that asks for an Australian address.
How to find an Australian postcode
- Suburb to postcode: choose “Suburb → Postcode”, type a suburb such as Bondi, Fremantle or Carlton, and optionally narrow it with the state menu.
- Postcode to suburbs: choose “Postcode → Suburbs” and type a full postcode like 2000, or the first digits like 30 to list every match.
- Copy the postcode, or open the area on a map to check it.
How Australian postcodes work
An Australian postcode has four digits, for example 2000 for Sydney. There is no hyphen or letter. Postcodes are managed by Australia Post and are used to sort mail.
Reading the digits
The first digit points to a state or territory. Broadly: 2 is New South Wales (and the ACT), 3 is Victoria, 4 is Queensland, 5 is South Australia, 6 is Western Australia, 7 is Tasmania, and 0 is the Northern Territory. The ACT uses some 26xx and 29xx codes inside the 2 range. Codes beginning with 0 keep their leading zero, for example 0800 for Darwin.
Suburbs and postcodes
A postcode can cover several suburbs, and a large suburb can have more than one postcode. That is why searching a postcode can return many suburbs.
Writing an Australian address
The usual order is unit and street, then the suburb in capitals, the state abbreviation and the postcode, for example: 1 Example Street, BONDI NSW 2026.
