Hi, can i have source code of get-australian-postcodes-inside-polygon.php ? I'm learning about finding zipcode in polygon area. Thank you so much!

When I included Groote Eylandt in the defined area it omitted any post codes on the island. This caused issues and inconvenience and ended up wasting time. Could you please ensure that all post codes selected are generated including on islands. It would be much appreciated. Thanks

BM, we cannot change back. We cannot afford to on this free-to-use site. An update has been made to allow the polygon to be edited.

Should not have changed this tool, we can cannot drag the point markers into position when zoning your desired area, makes things very difficult, please change back.

Hi Miguel, thanks for the suggestion - this is an interesting one! We will look in to feasibility
By Free Map Tools on 31st October 2018

This is amazing. What about a reverse function - you add in a set of postcodes, and then it'll highlight (or drop a pin) in each area?

LGA option has been added to the Future Ideas list.

Hi Paul, this sounds like what you talk about : Find Australian Postcodes Inside a Radius
By Free Map Tools on 19th November 2017

Excellent solution thanks. Has anyone come across a mapping solution that allows you to highlight a ring of postcodes, and then to get a list of every postcodes within that ring?
By Paul on 19th November 2017

Thank you so much! This is perfect for what I need, I have been looking for a while and had nearly given up thinking I could only search within a radius. Awesome tool :)

Robbo, this has now been added.
By Free Map Tools on 7th March 2017

Hi. This page is very helpful, but is it possible to remove duplicated postcodes (as you can on the 'within a radius' page)? I lose a lot of time manually removing them... Thanks!
