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.

I don't suppose there's a tool to list the village names not the post codes?
By Doug Woods on 25/04/2016

Hi James, you can do it using a combination of 2 pages on this site. If you use this guide [] but swap out anything do do with US ZIP codes with the UK equivalent ... []

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?
