Callpoint Spatial value-added G-NAF

Geoscape G-NAF (Geocoded National Address File) is Australia’s authoritative geocoded address dataset.


Callpoint Spatial packages G-NAF in various forms (e.g. flat text files, GIS).
We can also include attribution from other datasets to help meet your specific needs.

G-NAF with Enriched Attribution

Examples of attribution options in Callpoint Spatial’s value-added editions are listed below.
These enriched G-NAF editions can help meet your business requirements and are off-the-shelf.

The attributes below are not available in open G-NAF as specific supplier licensing is required.

G-NAF with Is Residential flag

Knowing whether an address is determined as residential or not finds application across the real estate, telecoms, demographic and health care sectors amongst other.


The Is Residential data is sourced from Geoscape Buildings.  Image of sample extract below.

G-NAF with Roads Hierarchy

This attribute categorises road centrelines.  Examples include National Highway, Arterial Road and Local Road.  Hierarchy is sourced from Geoscape Roads.


Callpoint attaches the Roads Hierarchy attribute to G-NAF.  This means that users obtain the road category against each address.  Applications range from Proptech property valuation models to a very basic traffic volume proxy for health researchers.

G-NAF with Non-Residential (and Residential) flags, DPID

If your application requires an explicit Non-Residential indicator and/ or Australia Post Delivery Point Identifier (DPID), please refer our Australia Post Postal Address File (PAF) page.

Why choose  Callpoint Spatial for G-NAF?

Our lengthy and in-depth G-NAF experience:

We engaged with Geoscape Australia (then PSMA Australia) regarding its forthcoming G-NAF during the first IPND address accuracy audit that we conducted for the Australian Communications and Media Authority in 2003.

We recommended that G-NAF be used as the address reference dictionary for future audits; this recommendation was adopted.

We pioneered the use of G-NAF in our Local Government Area (LGA) Broadband Analysis reports that we introduced in 2004.

We won the Metropolitan Broadband Blackspot Program (MBBP 2005) geospatial consultancy tender and extensively used G-NAF for that project.

We transitioned our address validation/geocoding engine to G-NAF during 2004, and this has since been extensively refined.


The engine is used by our Geocoded PAF production system.  Our geocoder is also embedded within Callpoint AQ Pro®.

Before the open G-NAF era, we introduced G-NAF to numerous Australian telcos to help meet their spatial and operational needs.
