FAQs

  • What are postcodes?

    Postcodes are a series of four digits that are used in Australia to efficiently sort and route mail within the postal system. The digits within the postcode are assigned to specific delivery points within Australia and are interpreted to ensure mail is delivered to the correct location.

  • Do the postcode digits have any meaning?

    Yes, each digit within Australian postcodes has a specific meaning. Australian postcodes consist of four digits and are often linked with one area or delivery point.

    The first number of the postcode usually specifies the state or territory, while the second shows the region within that state. Within regions with the same second number, the third and fourth digits are usually allocated in ascending order of distance from the states capital city.

    The data provided by these digits is interpreted by the mailing system to ensure mail is delivered to the correct location.

    For example, in the postcode 2450, the 2 represents the state of NSW. The 4 represents the north coast region of the state. The 50 represents the city of Coffs Harbour.

  • Where do you get your postcode data from?

    Addressfinder combines information from AusPost, the Australian Buerau of Statistics and Data.gov.au to produce Australia’s most comprehensive address dataset. Our address database is 100% verified by authoritative sources and updated regularly. We use this database to ensure our Australian address and postcode finder only returns accurate results.

  • How to get the Postcode Finder on my site?
