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.

This is great, I use it all the time.

Hi, I am just curious the distance between two post codes in your list is shorter different compare with google map. How would I know which one is correct. I have around 3000 post codes to check, so it takes long time to compare your list and google map. Is there a faster way?

Hi Tom, I have switched off the read only setting that causes this issue with the iPad

Can you add a copy to clipboard for the cvs? They are hard to copy from an iPad because of the size of the text area. Cheers

sandie, this is not possible. As you say it only outputs full postcodes up to 12.5 km

i am working on a project to map all postcodes within a 25 mile radius at 2.5 miles intervals. can this be done? i see it can get all postcodes mapped up to 12.43miles

Hi Lee, unfortunately searches can only be done one by one.

hi - is it possible to put more than one postcode within the search parameter with appropriate radius to allow to extract just one table?
By Lee on 23/07/2015

Hi Rebecca, this can be done using multiple pages. Please refer to List USA ZIP Codes Within a Drive Time Radius but use Find UK Postcodes Inside a User Defined Area instead at the end.
By Free Map Tools on 09/07/2015

We see you have a tool to find Postcodes within a distance radius or distance by time, is there any chance of combining the two so we can find postcodes by time radius.

Hi Kn, this is not possible on the map on this page. It sounds like what you are requesting could be done if someone took the time to write a custom map to show what you require.

Hi, I am working on a project where we are trying to map how far any family has to travel to find a child adoption centre. I find your mapping tool really useful for this exercise. I need to visually show the locations of all the adoption centres and then be able to show what is the maximum distance any family anywhere in UK will need to drive to find their closest adoption centre. How can I show all the adoption centres as points on the map? Thanks in advance for your inputs.

Hi Zak, It is not possible on this page but you may be able to work something out yourself using the raw data on Download UK Postcodes with Latitude and Longitude.

Hi Team, great website by you guys. Has helped me a lot so thank! But is there anyway I could get the FULL postcodes for 25km/15mi radius and not just the outcodes?
