Distance Between UK Postcodes
This tool can be used to find the distance between postcodes in the UK. Type in the two postcodes and click the Show button.
Map Showing the Distance Between Two UK Postcodes
Switch to Full Screen
Use the text box below to input bulk postcodes and find the 'as the crow flies' distances between them. There is a limit of 200 pairs at a time. Add them in the format postcode1,postcode2 per line. Once processing is complete, the distance is appended as a 3rd column on the CSV list. You can toggle the units (miles/km) using the switch above.
If any postcodes are not found, the tool will output the distance as NF (1st PC NF) or NF (2nd PC NF) to indicate it was the first or second postcode at fault
How to Use Postcode Tool
Type in the first and second postcode then click the Show button. The map will then display the location of the two postcodes and also show the routes for:
- As the crow flies - the straight distance between the points
- By land transport - by car and/or boat
You will also see the distance displayed below the map for the distance as the crow flies and also by land transport. You can then type in more postcodes and click the show button to see more distances.
Note : This Postcode distance finder will measure the distance between full UK Postcodes.
Format of Outward Code / Out Code
Use the format "A(A)0(0)(A)", where:
- A is a character
- 0 is a digit
- () means optional
Format of Full UK Postcode
Use the format "A(A)0(0)(A)_0AA", where:
- A is a character
- 0 is a digit
- () means optional
- _ is a space
So any input of 2,3 or 4 characters is assumed to be an Out Code format and anything longer than 4 characters is assumed to be a full UK postcode.

Hi, what method are you using to calculate as the crow flies? I have tried to replicate this value using Pythagoras Theorem and HaversineCircle, but neither match.
By Haversine Pythagoras on 6th January 2019
Hi, it adds another column (comma separated value) on to the list. So if you input [TD1 3HX,B50 4FQ] it will display [TD1 3HX,B50 4FQ,240.868]

Hi there, Thanks for creating this! Is there a way to bulk process the road distances rather than crow flies distances? Tim

Hi, Wondering if you could make this tool available for the dutch postcodes (4digits) as well?
By wink on 14th November 2018
To confirm the format expected, for example:
M33 7XQ,SA62 5AY
M41 5PL,NG17 1NS

If you paste the postcodes leave spaces in comma separated - works fine
Great bit of coding - thanks

Hi Matt, thanks for the feedback. Do any 2nd postcodes for for you? What is the postcode that doesn't work? What happens if you swap the first and second about?
By Free Map Tools on 6th November 2018
Hi, the bulk processing doesn't seem to be working? Keep getting "NF (2nd PC NF)" even though it is a valid postcode and works fine in the individual search. Using IE. Thanks.

Hi Andy, the data is in CSV format on the page, but not saved to a file. You will need to copy and paste it in to your own file.
