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?

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

Hi great tool, you wouldn't happen to have any sample code would you? 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

Hi Paul, this is not possible as we do not have the dataset required to do this. So, not saying it cant be done (technically), but not here unfortunately.

Hello is it possible to find out how many addresses per selected defined area? I can find postcodes per area, but how to work out how many households/addresses? Thanks Paul
By Paul on 15th November 2015

Hi Simon, you can take a screenshot while in Full Screen mode and also use the list below the map to get the list of postcodes contained in the area.

Hello, Can you create an area and export the graphic and the list of postcodes contained within?
By Simon H on 22nd October 2015

Just what I needed - thank you so much. Quick and simple - Thank you!!

Hi Tom, it is done on an ad-hoc basis. So nothing regular, but we do make updates from time to time.
By Free Map Tools on 7th July 2015

How up to date are the postcodes? are they updated regularly or automatically updated with new postcodes? Cracking piece of kit and just what I needed btw, so thanks
By Tom on 6th July 2015

Point taken. We have made some updates to the instructions.
By Free Map Tools on 11th May 2015

Worked well, but only by trial and error to find how to define an area. Instructions not clear at all and should be rewritten.
