Step 1 : Radius km (maximum = 320km) OR miles (maximum = 200 miles)

Step 2 : Click on map OR Place radius by location name or postcode :

 Draw Radius 


 Toggle CSV or New Line 


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 5km 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 am Sorry if I am not getting It. But i cant find download link of this tool. I have downloaded SQL query i need code for this tool.

Hi there. Great site and been massively helpful in a bit of work I am doing. When I get the list of full postcodes there are a fair number where you do not get the full postcode but you get, for example, M61 0D (so missing the final digit) or I get M60 1L - again missing the last digit. The query is does the missing digit mean that all possible final digits are included, so for example M60 1L covers say M60 1LA to M60 1LZ or is it something else? Thanks very much.

Hi, it is as the crow flies.
By Free Map Tools on 23/03/2014

Amazing resource - thanks for all your effort, hard work and generous help! Just one question - is the radius interpreted "as the crow flies" or "via actual roads"? I presume is the former but it does not seem to be explicitly mentioned (or I couldn't see it).

Hi Ian, This is done to help performance for all users as it is intensive on the database. If it was increased, all users would notice poorer performance.

Fantastic tool but is it possible to increase the 5km limit for displaying full postcodes to 10km?
By Ian on 05/03/2014

Found it! Great tool, really making my life easier. Keep up the good work.
By Greg G on 10/02/2014

Hi, is it possible to put multiple post codes in so i can see the radius of each one on the same map?
By Greg G on 10/02/2014

Hi, we have not taken the time to design this to work on other websites. Also, we cannot take time to support others implementing it elsewhere so unfortunately we cannot offer any help doing this.
By Free Map Tools on 10/02/2014

Great Uncle Honk, yes, you can on the page Find UK Postcodes Inside a User Defined Area.
