Step 1 : Radius km (maximum = 320km) OR miles (maximum = 200 miles)

Step 2 : Click on map OR Place radius by location name or postcode :

 Draw Radius 


 Toggle CSV or New Line 


Input a radius to search within in KM or miles. Click on the map or type in an address or postcode on the center of your search. After a delay, the results will appear inside the radius. If you hover over a marker, you will see it's outcode postcode.

Any radius less than 20km will return full postcodes, anything more will return outcodes only.

The list of Post Codes inside the radius will be displayed in the textbox. You can toggle between CSV or new line output by clicking the [Toggle CSV or New line] button above the textbox.

Hi, 25 mile radius from PO19 works OK at our side. We thought perhaps it was a 'big' search but this is not the case. Can you try a different web browser and see if this helps?

Hi, I am searching a 25m radius from PO19

Hi, where are you searching and how big is your radius? Are there any JavaScript errors?
By Free Map Tools on 02/09/2014

When searching, I don't get any results either (similar to the previous comment). The 'Searching' icon just keeps on going round and round.

Hi, can you describe the search you are doing? the Radius and the center point? Thanks.

Hi, when I search for a radius it shows on the map but doesn't show the post codes, it just keeps searching

I am using Windows Internet explorer, IE8.00 in a corporate environment, so I am unable to use a different browser. A colleague has also tried on a different computer but has the same issue.

Hi Karen, thanks for the info. We have tested this and it works fine for us on multiple browsers. Can you confirm which browser you are using? Also, can you try it on a different computer please?

I have tried multiple codes, but most recently DA15 with a 5 or 25 mile radius. I have cleared my cookies and browsing history, but it has not made any difference.
By Karen on 30/07/2014

Hi, can you confirm the radius you have specified and the location you are searching please?
By Free Map Tools on 30/07/2014

Karen To confirm I have had the same issue and had to use an alternative website. The radius appears on the map, however the output wheel shows as searching only

Hi Karen, as far as we know (and see) it is working. Have you tried deleting your temporary internet files, or used a different web browser? If it still doesn't work, please describe what you see, or doesn't see?

I use this tool all the time, but the postcodes within a UK radius has not worked at all since early July. Has anyone else had an issue? Thanks

Hi Ray, what do you have to go on? Do you know the location of the unknown postcode on a map?
By Free Map Tools on 23/07/2014

cant understand or use this much needed tool. i just want to find a postcode - spent a long time failing
By Ray on 23/07/2014

Hi, yes, you found a bug. Thanks for reporting. It should now be resolved.
By Free Map Tools on 03/07/2014

Trying to do a 100, 150 and 200 mile radius of a postcode and its giving me the same amount of postcodes for each one (1397 postcode districts) think there may be a fault

Hi Jack, Unfortunately it is just one at a time.
