Find UK Postcodes Inside a User Defined Area
This is a map of the UK where you can define an area and then search to return all postcodes inside the area.
UK Postcode Inside Area Map
Options
Upload KML File
CSV Output
List of Postcodes found...
Instructions
- To define an area, click on the map to draw the edges of your search area
- Draw the area in a clockwise direction
- You can readjust markers once they have been drawn by dragging them to a new location
- Once you have an area defined, click the [Search For Postcodes] button. After a short while the postcodes will be displayed on the map and also listed in the textbox below the map
Other Points to Note
- The search will take a long time when you are searching a larger area or a densely populated area
- You can clear the map by clicking the [Clear All Points] button
- You can switch to a full screen view by clicking the [Full Screen] button
- Click [Zoom to Fit] to get your area to fit on the map as best possible
- Click [Search For Outcode Postcodes] if you only wish to find the outcode postcodes (SW1,DE2,BT12 etc...)
- You can remove the last point added to the area by clicking the [Delete Last Point] button. You can also remove an area end-point by clicking on the endpoint

How upto date are the postcodes?
Hoping this worked?
Did that work? Thanks Dean
This is for 158 Allport Road. Postcodes CH62 and CH63 postcodes
CA, that's an interesting idea. We will look in to it.
Reverse Feature/Functionality please ?? ability to enter a list of postcodes and it draws a polygon box that can be exported as a file
Hi, I need to combine two separate functions currently offered on this platform. Firstly I need to create a radius around a UK postcode. Then I need to customise this by removing/reshaping certain parts of the radius to exclude certain areas, but still retaining the reset of the circular radius previously defined. For e.g. firstly define a 3 mile radius but then cut the righthand side of the radius to remove certain areas, but again retaining the radius on the left.
Hi Pavel. Just tested a KML and it worked ok for us. Where has your KML be exported from? Which application?
Great tool, but can you check, if KML upload is working? Tried to upload a *.kml a couple times, no luck.
Sarah, have a look at Find UK Postcodes Inside a Radius.
Fantastic little tool. What would be really nice is the ability to put in a location, specify a radius and be able to list the postcodes within that area.
Really great tool here. Works well and very easy to use. I'm doing some work on properties within zero-emission zones and this has turned a potentially painful experience into a breeze. Thank you so much!
KML Upload is working again.
Awesome site with great functionality at the perfect price! However for some reason KML upload on the UK postcodes inside user defined area page seems to have stopped working in the last month. I have asked a few friends to try it and used KML files that definitely worked in the past.. I would really appreciate if you can find a resolution to this..! Thanks again!
Hi, it sounds like the search many be too large or the number of results too high. Can you reduce the search and see if it works then? If it does, try splitting the search in to separate smaller searches and combine the results at the end.
Is there a reason why mine isn't working to generate the postcodes. I have managed to successfully generate them once but on 6 other occasions the page just says "please wait" and never generates - and I have waited days!! I have tried both chrome and safari but do you have any tips?
This is a great tool! :) I would also really like sector (the outcode areas are too big... and individual postcodes return thousands of results). @Ian - re "Hello, it it possible to export the postcode sectors only that appear in the plotted area - E.g NR14 8, NR14 7, IP7 7?" - did you ever find a script/solution for this? Thanks
Many thanks
Chris, you are able to use the [User Menu] at the top right to save an area. This will keep it stored in you browser cache for a while. You can also Export Data to export the saved data as an XML file. The XML can be imported in future to reload an area on this page.
Chris, your query has been noted. Leave this with us...
