Bulk Processing

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.

Uses of This Postcode Tool

This tool has a wide range of possible uses from delivery estimation to point to point measurement. If you know of a useful application of this tool, let us know.

John Eden, we are not providing negative feedback, its constructive feedback, if the site doesn't work shall we all sit here in silence and happily record nil distances! Again thanks Free Map Tools, a fantastic website! The postcode to postcode now works again! :)

Hi, Tying to use the Postcode 1 to Postcode 2 tool and it doesn't appear to be working. The distance boxes remain as 0? This has happened both yesterday and this morning? Is there a glitch? Many thanks.

John, we tend to avoid asking for donations as the level of expectation for the various tools is already high without any 'donation' in the mix. If you could let others know about Free Map Tools, like the Facebook page and Follow the Twitter account, this would be much appreciated.
By Free Map Tools on 27th September 2018

Now and then Wikipedia asks for donations towards maintaining their free site. Do you do something similar? I've been using your excellent facility for around ten years now and feel I ought to contribute something. I've never been disappointed with the results I get from Free Map Tools and am constantly amazed by those who offer negative feedback. It's free. folks. . .
