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 :

 Clear Map

CSV Postcodes with distance (postcode,km,miles)


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.

Comments For This Page

There are no known issues right now. Can you confirm the input the criteria you used please?

Is there an issue with this site as when inputting the criteria to draw down on a radius and selecting output codes only, when pressing on the search button - nothing happens ?

Jrais, please try Find UK Postcodes Inside a User Defined Area.

Hi can you draw the area you want a list of postcodes rather than a diameter circle?
By Jrais on 15th November 2019

Dorian, you can copy and paste it in to a text file and save it as filename.csv

How do you export the CSV data?
By Dorian on 30th September 2019

Is there any chance this could give driving distances rather than point to point? If not, could you point me in the right direction as to where and how I could find that information (eg: OSM?).

Hi Claire, please try : Distance Between UK Postcodes.
By Free Map Tools on 20th May 2019

Is there an option which gives time taken for travelling distance between postcodes?
By Claire on 16th May 2019

Graham, for the doughnut, this is not possible to do on this page, but you can subtract results of A from B to get the same output. In terms of speed, I agree that some searches return 1000\'s of results and web browsers do take their time to process and display all this data. We take the approach that it\'s better to let users do larger searches and wait for their browser to process it rather than put a lower radius limit on searches just to avoid comments such as \"its a bit slow\". Also, 30 miles in a less populated area will be relatively faster than a populated area i.e. the South East.

would it be possible to do a doughnut shape search for say between 10 and 20Km? that would allow for me to build up search areas easier. worked great for me but trying anything over 30 miles is too slow. Thanks

Hi, for the large amounts of data that can come about, the browser will sometimes be under pressure and slow down. We could limit the amount of data or the radius that can be input but then I'm sure there will be complaints about that. So this is due to the sheer amount of data.

option for copying list of postcodes? its so big Its taking forever to scroll and select
On 6th February 2019

Is it possible to only see the first part for the cost code in the list - ie. IP1, rather than IP1 4JJ?
By Barry on 4th October 2018

Carwyn, we have just updated the data. This should now work.
By Free Map Tools on 3rd October 2018

SA33 5EZ from SA33 6EH showing no results. Postcode is correct according to Royal Mail
By Carwyn on 2nd October 2018

This is fantastic, thank you very much for putting this together.
By Oliver on 27th September 2018

Josh, it is due to the sheer amount of data trying to return. Yes, the website should cope better but at this point in time there is no quick bug fix.
