Hello! I have uploaded a KML file and turned on the toggle for FSAs, but it is taking a long time to pull any data (still have not received anything) Is there anything else I should be doing?

Yes, it is KML. I tried a smaller radius to see if it was the size but nothing loads. Any suggestions?

KML from Google Earth Should work. Are you sure it is KML and not KMZ?

Hi - Unable to upload KLM file generated from Google earth. is this possible?
By Sukh on 24th March 2023

CM, it could be an issue of too large an area. Could you first try a test, smaller area to see if this works? You may need to split your original area up in to parts and then combine the results at the end.

Hello! I have uploaded a KML file and turned on the toggle for FSA's, but it is taking a long time to pull any data (still have not received anything) Is there anything else I should be doing such as a way to compress the KML file?

That did the job - thank you!!!

Eddy, can you try it while the tickbox for [Only return Forward Sortation Area (FSA)] is on?
By Free Map Tools on 9th April 2021

Hey team, this is an awesome app and is super convenient. I used it a few months ago and it worked like a charm - now I'm trying to use it again for the same kml file and it simply does upload/generate? I've left it running for a log time, used different browsers, etc and still no luck - any help would be appreciated!

Disregard previouscomment. selecting [Only return Forward Sortation Area (FSA)] has solved the issue. Before it was simply trying to populate too many postal codes at once!

After selecting an area on the map the page freezes up after clicking "search for postal codes" Tried with chrome and microsoft edge.

Thanks, I got it to load, although the results are inconsistent.. I am trying areas I have marked for Toronto, ON and getting MB results (R0B).

Hi Steve, try clicking the button [Search For Postcodes] after it has loaded the KML.
By Free Map Tools on 8th December 2020

I am unable to load a KML file. The page displays 'List of postcodes found...' but nothing generates.
By Steve on 7th December 2020

The KML issue should now be fixed

Thank you for creating this; it is very useful!

Hi Thomas, can you confirm where the KML file was exported from? Which software or system? This will hopefully allow us to test the formatting of the KML file
