Find UK Postcodes Inside a Radius

Map of the UK where you can specify a point and a radius to search within and return all outcode postcodes inside the radius.

UK Postcode Radius Search Map



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

Step 2 : Click on map OR Place radius by location :



 Full Screen 

 Clear Map 

Show Centre Marker? Show Postcode Labels? Only Output Outcodes? Show UK County Borders?


 Toggle CSV or New Line 

CSV Postcodes

 Save CSV File 

CSV Postcodes with distance (postcode,km,miles)

 Save CSV File 


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.

Sorry, that's not possible.

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

Hi, I am trying to use your postcode generator to give me postcodes within 3.5 miles but its including postcodes at 5.5 miles
By ROSS on 12th June 2020

Hi, this is great! Another request to have postcodes distance specified by Land Transport please. Thank you!
By Annie on 8th June 2020

Hi Philip, data is updated around four times per year. So updates will eventually feed through, but will take a bit of time.
By Free Map Tools on 3rd May 2020

How up to date are the post codes that are returned? how often are they updated? Will there be some newer ones missing e.g. new housing developments?
By Philip on 30th April 2020

Great tool, will be processing the results myself shortly to filter all the postcode areas, might be an idea for future updates!
By Tom on 18th March 2020

Denis, your suggestion has been added.
By Free Map Tools on 28th February 2020

Great tool! only one suggestion that an export csv button can also be added to export postcodes with the distance beside each (as displayed in bottom box).
By Denis on 19th February 2020

Alex, if you tick on the [Only Output Outcodes?] setting, this should do what you want.
