G-NAF (Geocoded National Address File)

The Geocoded National Address File (G-NAF) is Australia’s trusted source for geocoded address data, built and maintained by Geoscape Australia using verified government data. G-NAF aggregates over 50 million contributed addresses, condensed into 15.4 million unique, validated addresses.

G-NAF provides a powerful spatial dataset with more than 15 million Australian physical addresses. Each address is identified by a unique code, the G-NAF-PID, ensuring consistent identification of all addresses across Australia. Importantly, G-NAF does not contain personal information about individuals or households.

How G-NAF Benefits Your Business:       

G-NAF is essential in ensuring accurate geospatial data. SamplePages leverages the G-NAF to provide superior sampling capabilities. With G-NAF-PID, we can now sample by dwelling or unique address more efficiently. This enables the ability to:

  • Limit records per dwelling for targeted research
  • Manage top-up samples to avoid contacting previously surveyed addresses
  • Improve the precision of address-based data collection for market research

Whether you’re conducting national surveys or delivering location-based services, G-NAF ensures that your data is accurate, reliable, and comprehensive.

Full Address

Some of our clients have found great success in improving response rates through conducting a mail out of notice to the home of the survey respondent flagging with them that they have the opportunity to have their voice heard on matters affecting their local community in an upcoming market research interview call.  

Formerly the ability to conduct a mailout prior to a market research project was only possible if our clients were to deliver a list of street addresses which we append data onto. Whereas now any sample can now be exported with full address details to conduct a pre-survey mailout.  

Geocoding

We offer efficient processes for cleaning and normalising location data, converting addresses into precise latitude/longitude coordinates. This enables broader spatial analysis for applications such as market research and logistics. Our geocoding ensures accurate and actionable insights for location-based decisions.
