CSV Postcodes

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.

Saff, this isn't possible to filter out on this page. The only suggestion is to get the full postcodes then use a spreadsheet or script to extract the postcode sectors and group unique values.

It's very helpful thanks but how can I limit to just the district number only i.e. St6 5 rather than st6 5de

Alfred, it is only possible to do one-by-one on this website. Running in batch would have a cost. Get in contact if you wish to discuss.

If I have a list of postcodes that I need a radius around (~150 postcodes), is there a way to run them all at once or only one by one?
By Alfred on 6th July 2017

I will try to work with you to see how is going.Thank you.

Hi abdulwahid, Can you explain what steps you take on this page and where it stops working please?
By Free Map Tools on 6th June 2017

Hello, why isn't this page working?
By abdulwahid on 6th June 2017

Edvin, not sure what you mean. Could you give a bit more detail please?

Is there any API for this feature so i can consume it as a web service?
By Dave on 3rd March 2017

I love this website. I was in search to find out the the UK post codes within 3 and 5 miles radius and this this website gave me all required details in the format what I actually want. Thank you and really appreciate the developer of this website.

Do you and are you willing to share the SQL/MySQl code that calculates this?
By Stuart on 25th January 2017

Dave, for performance reasons this is kept limited. Once the radius size gets so large there is an impact on the service for all users.

Please could we have FULL UK postcodes inside a radius beyond 20km? I need to calculate full postcode & distance up to 60 miles from a central point.
By Dave N, Bristol on 5th October 2016

Great, fingers crossed
