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.

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.

Robert, sorry this is not possible.

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.

Hello again, ignore previous comment. I found what I was looking for here - https://www.freemaptools.com/find-uk-postcodes-inside-radius.htm
Thanks for making this website, its great.

Hello. I would like to use this postcode finder but by using a mile radius from a certain postcode (like your 'Radius From UK Post Code Map' rather than drawing it out myself (which would take a while and wouldn't be accurate). Is there any way I can dow this? I'm wanting to find all full postcodes within a 12 mile radius of Inverness. Thanks, Mark
By Mark on 14th February 2017
Hi great tool, you wouldn't happen to have any sample code would you?
On 24th April 2016
Amazing tool. Good work. Thanks.

Hi Rob, I have done some investigation in to this. There is no quick/easy solution but if you get in contact [here] I have a suggestion.

Hi. Im looking for a map that just defines borders of smaller sectors (EG, in the WA postcode you have WA9, WA10, WA11. In each of these, you then have smaller sectors such as WA9 1, WA9 2, WA9 3, WA9 4, WA10 2, WA10 3 and so on - I want these smaller sectors outlined).
I did find an online map not long ago that showed these borders, but now they never load up :(
Possible to get these on this map?
By Rob on 1st March 2016
Brilliant - thanks you
