  4. Once you have an area defined, click the [Search For Postcodes] button. After a short while the postcodes will be displayed on the map and also in listed in the textbox below the map

Other Points to Note

  • You can clear the map by clicking the [Clear All Points] button
  • You can switch to a full screen view by clicking the [Full Screen] button
  • Click [Zoom to Fit] to get you area to fit on the map as best possible
  • Click [Search For Outcode Postcodes] if you only wish to find the outcode postcodes (SW1,DE2,BT12 etc...)
  • You can remove the last point added to the area by clicking the [Delete Last Point] button. You can also remove an area end-point by clicking on the endpoint

Future Ideas

  • Allow KML (polygon) upload to draw the area

Comments For This Page

This is a great tool! :) I would also really like sector (the outcode areas are too big... and individual postcodes return thousands of results). @Ian - re "Hello, it it possible to export the postcode sectors only that appear in the plotted area - E.g NR14 8, NR14 7, IP7 7?" - did you ever find a script/solution for this? Thanks

Many thanks

Chris, you are able to use the [User Menu] at the top right to save an area. This will keep it stored in you browser cache for a while. You can also Export Data to export the saved data as an XML file. The XML can be imported in future to reload an area on this page.

Chris, your query has been noted. Leave this with us...

Would it be possible to allow KML output as well as input? This would allow me to re-upload and tweak a previously exported area. Thanks, Chris
By Chris on 25th May 2020

Hi Ian, sorry that's not possible on this page. You may need to use some scripting to manipulate and group the results.

Hello, it it possible to export the postcode sectors only that appear in the plotted area - E.g NR14 8, NR14 7, IP7 7?
By Ian on 27th November 2019

Gary, a Download CSV button has been added below the Output CSV textbox.

Thsi is a great tool, is it possible to export the postcodes into a Excel or CSV File?
By Gary on 21st October 2019

Hi! Really great tool you've written here - thanks! There appears to be an issue with drawing an area though where waypoints 'spawn' each time they are edited i.e. after drawing the initial polygon, when you add more waypoints, rather than getting just one additional waypoint, you get several. Would be great if you can fix :) Happy to send a video if that helps. Thanks again.

make it usable ie postcode miles enter simple

That's great - thanks!

Tom, an option has been added to allow you to stop this. There is a new tick box below the map

Is it possible to disable the automatic zoom to fit after every click?
By Tom H on 5th March 2019

Steph, we will add this to a Future Ideas list.
By Free Map Tools on 12th December 2018

Hello. Can the tool be modified so that it recognises KML uploads?
By Steph on 10th December 2018

hi great tool. It would be handy if you could download the coordinates and re upload later so you can make adjustments to the area.
By Gary on 13th September 2018

Robert, sorry this is not possible.
By Free Map Tools on 13th March 2018

Great web tool. Any way of determining how many households are in the search?
By Robert on 13th March 2018

Hi Mark - Good to hear you found it.
