Data sources

Addressfinder's autocomplete and verification services utilise the Addressfinder address database. Addresses are sourced from official sources such as The Australia Post PAF, G-NAF, NZ Post PAF, LINZ AIMS, Stats NZ, ESRI, HERE and our own database built over the last decade.

We update our address database monthly to ensure data freshness.

Australia data sources

Addressfinder's Australian address data comes from three main sources:

  • The Australia Post PAF The Postal Address File is owned, controlled and maintained by Australia Post. In addition to containing every deliverable address in Australia, the PAF also contains the DPID of address and also GPS coordinates for the majority. Like the Addressfinder database, the PAF is updated on a monthly basis.
  • Geocoded National Address File (G-NAF) maintained by Geoscape Australia. As the name implies, the GNAF contains GPS coordinated for 100% of the addresses in the database. The addresses in the GNAF are the legal/physical addresses. These are sourced from multiple reputable sources such as local and Federal Government entities.
  • Australian Bureau of Statistics The ABS is Addressfinder's source of census and geo-political related address metadata. This metadata is used to suppliment addresses from the GNAF.

Every verified address can be returned with a range of metadata, see the available Australia addresses metadata
