This is amazing. I was astonished that even zip code data is proprietary data of the USPS in the United States. It&#x27;s possible to &quot;reverse engineer&quot; the data from publicly available census data (zip code tabulation areas) which is what I do and publish for free on ZipLocate[0]. Comparable datasets cost $499.<p>Canada&#x27;s situation is even worse. Geocoder.ca has been sued by Canada Post[1] to take down their data (which Canada Post was selling for $5000).<p>The whole address data situation is really terrible. Glad to see Australia opening up the data.<p>[0] <a href="http:&#x2F;&#x2F;ziplocate.us&#x2F;" rel="nofollow">http:&#x2F;&#x2F;ziplocate.us&#x2F;</a><p>[1] <a href="http:&#x2F;&#x2F;geocoder.ca&#x2F;?sued=1" rel="nofollow">http:&#x2F;&#x2F;geocoder.ca&#x2F;?sued=1</a>
