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

By bollos on 7th January 2020

Any chance of adding "by land transport" to the bulk service alongside "as the crow flies"?
By Mark on 10th December 2019

Depends on if the Crow is sober and on a direct mission without stopping at relatives...
By Bob on 28th November 2019

Is there an option to get bulk distances by Land transport and not just as the crow flies?
By Stephen on 15th October 2019

How do I output a bulk run?
On 9th October 2019

Thought I'd found just what I needed - but the distances are so far out its pointless in using as it defaults to "crow flies"
By Stuart Harrison on 2nd August 2019

Did you have a space after the comma? It expects no space
By Free Map Tools on 2nd August 2019

I entered the same Postcode 1 and postcode 2 into Options and Bulk Processing. Options was able to produce a result but Bulk Processing states NF (2nd PC NF)

I initiated a Smart Working scheme at my company and this tool has helped me to measure benefits of saving travel time. The bulk function is brilliant !
