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.

Hi, I am currently trying to update our system with postcode distances for lots of projects, this bulk postcode tool is what I need, however, it looks like it calculates as the crow flies and not road distance. Is there an option to change it to road distance as this would really help? Thanks, Emma

I wanted to know how far it was to walk from a Premier Inn to an anniversary event I was invited to. The answer was given to three decimal places and the map gave the best route. A brilliant tool. Many thanks.
