Find UK Postcodes Inside a Radius

Map of the UK where you can specify a point and a radius to search within and return all outcode postcodes inside the radius.

UK Postcode Radius Search Map



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

Step 2 : Click on map OR Place radius by location :



 Full Screen 

 Clear Map 

Show Centre Marker? Show Postcode Labels? Only Output Outcodes? Show UK County Borders?


 Toggle CSV or New Line 

CSV Postcodes

 Save CSV File 

CSV Postcodes with distance (postcode,km,miles)

 Save CSV File 


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.

Steve, have a look at : Radius Around a Point on a Map.
By Free Map Tools on 26th January 2023

Be good to just show a radius round a point without showing any markers.. and I suppose that would be simple to do.

Hi Andy, do you have an example of a postcode you have input?
By Free Map Tools on 14th September 2020

Doesn't seem to work - just getting "not found" for any postcode entered.
