Our location dataset for Australia

Explore our comprehensive collection of Australia ZIP code and administrative data products, designed to meet all your mapping and location intelligence needs.

Australia ZIP Codes

Australia uses a “Postcode” system, which is a four-digit numeric format, like 9999, with no letters or separators. This means it uses only numbers, unlike US ZIP codes which are also numeric. However, US ZIP codes are five digits long compared to Australia’s four. According to the GeoPostcodes world postal code database, Australia has 2,937 postcodes covering 574 regions and 16,010 towns.

Australia ZIP & Administrative boundaries

Australia administrative landscape often follows inconsistent regional models and irregular public sources, making it difficult to maintain reliable boundaries. Our standardized postal and administrative boundary data resolves these gaps to ensure complete, coherent geographic coverage.

Australia Administrative Divisions

GeoPostcodes provides a standardized reference for Australia’s address structure, ensuring consistent, accurate, and globally aligned formatting across your systems. The dataset captures the official address elements required by the national postal operator and maps them into our unified global schema.
