title: Software using google API returns incorrect information
body: <p>I've been having an issue generating a geocode map of a large list of postcodes (~29,000) online, and finally found a site named 'EasyMapMaker'. It seemed to work fine, although took a very long time as expected, but a great number of postcodes are not in the correct location.</p>
  
  <p>When entering these postcodes into google maps, they are not recognised or incorrect. I assume then that the errors in EasyMapMaker, which uses the Google geocoding API, are related to google.</p>
  
  <p>My question is, Is there an alternative free software with a large data limit that functions off of something other than the Google Geocoding API, and is likely to be faster with less margin of error?</p>
