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.

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.

is there a way to do bulk postcode but to get the land transport mileage and not as the crow flies miles.
By Bernie on 20th June 2018

Hi Howdy, are you using "W3" or a postcode beginning with W3?
By Free Map Tools on 18th June 2018

The programme doesn't seem to know that W3 is in London. Depending on the way you enter the search (I tried all manner of formats, underscores) it puts W3 either in Manchester or near Glasgow.

Excellent site, very helpful
By Mark on 15th February 2018

Great tool, thank you! Would love an option to do road distance for bulk updates rather than crow fly - although I appreciate this free tool!

This tool is incorrect - distance between E1 and E8 not 10 miles.
By Claire on 24th January 2018

Really useful, but would like bulk process for land distances please.

Hi, can you give an example of a duplicate please?
By Free Map Tools on 22nd December 2017

Fab tool, but doesn't seem to like duplicate postcodes when batch processing!

Great for route planning vehicle and bicycle with added confidence.
By Tom Wilson on 9th December 2017

Really good, now if only you could also have a 'mass' checking by Distance Land Transport as well as 'crow flies'...
