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 Ray, what do you have to go on? Do you know the location of the unknown postcode on a map?

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.
By Free Map Tools on 22/05/2014

Hi Colette, It is not possible to do this directly. Unless there is a way to filter out postcodes based on their prefix?
By Free Map Tools on 22/05/2014

Great tool thank you. Is there a way to put multiple postcodes in, see the radius of each one and the postcodes they cover?
By Jack on 15/05/2014

Hi - I would like to get postcodes by UK county - is this possible?
By Colette Cox on 15/05/2014

It has now been increased to 20km.
By Free Map Tools on 12/05/2014

Is it possible for you to increase the distance to 15km to show full postcodes? That would be brilliant.

Hi Scott, These type of postcodes are errors. We will try and remove these.

By Free Map Tools on 14/04/2014

I am Sorry if I am not getting It. But i cant find download link of this tool. I have downloaded SQL query i need code for this tool.

Hi there. Great site and been massively helpful in a bit of work I am doing. When I get the list of full postcodes there are a fair number where you do not get the full postcode but you get, for example, M61 0D (so missing the final digit) or I get M60 1L - again missing the last digit. The query is does the missing digit mean that all possible final digits are included, so for example M60 1L covers say M60 1LA to M60 1LZ or is it something else? Thanks very much.
