Instructions

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.

We are doing some work for UK Blood Bikes do you have an API,

Steve, have a look at : Radius Around a Point on a Map.
By Free Map Tools on 26th January 2023

Be good to just show a radius round a point without showing any markers.. and I suppose that would be simple to do.
By Steve Parky on 25th January 2023

Gg, please get in contact to discuss.
By Free Map Tools on 25th February 2022

Does this have an API available for me to use in my program?
By Gg on 24th February 2022

does not appear to work

Lee, no it's not possible to search for boroughs.
By Free Map Tools on 1st November 2021

Can you search for boroughs within a radius
By Lee on 31st October 2021

Sorry, that's not possible.
By Free Map Tools on 20th July 2021

HI , Is it possible to search more than one postcode at a time ?
On 19th July 2021

What did you input?
By Free Map Tools on 17th January 2021

Just tells me not found?
By Christina on 17th January 2021

Is it possible to get all the postcode districts within a drive time of a specific postcode?
By Alex on 3rd December 2020

I hope you can help as I am trying to get a map that has a 10km reaadius from ox11 7le. but I need it to show all the postcodes in that area, like this (OX11 1, OX11 2,) This is so I can plan deliveries.
By RALEIGH HULLOCK on 27th September 2020

Hi Andy, do you have an example of a postcode you have input?
By Free Map Tools on 14th September 2020

Doesn't seem to work - just getting "not found" for any postcode entered.
By Andy on 10th September 2020

Hi Pam, yes, you can do it on this page : Find UK Postcodes Inside a User Defined Area.
By Free Map Tools on 5th September 2020

Hi there, is there a way where you can draw a shape- other than a circle, eg a polygon connecting all the desired points- directly onto the map and then obtain the postcodes within that shape? Cheers
By Pam on 3rd September 2020

Hi, thats not possible right now. You could use some scripting to parse the results and return the Sectors.
By Free Map Tools on 20th August 2020

Would be good to be able to get postcode sectors e.g BN1 1, BN1 2
