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. For Example TR20 8QJ,KY5 0AT. 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.

How do I extract the data from Bulk Processing?
By Oakley on 16th February 2023

Hi Jmac, for cost reasons this is something that is not feasible to implement.
By Free Map Tools on 3rd February 2023

Great potential but something I cannot use as I need to see distance by Land Transport as opposed to as the Crow Flies for the bulk processing. Perhaps you could consider allowing Land Transport for Bulk Processing in a future update?
By Jmac on 3rd February 2023

Almost what i needed. Would be much more helpful if the batch processor showed more info, like time to travel by car to each post code. Distance as travelled by pigeon doesn't really help much. Nice programme though, but would prefer more useful output from the batch processing.

Would be nice to be able to call from a spreadsheet with 2 postcodes and get the "Distance by Land Transport" returned.

Hi, great tool. Is it possible to enable bulk processing of distance by road transport - that would be SO useful, Thanks
