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.

Hi, this is such a useful tool. Thank you. Is there a way to do bulk processing to get Land transport and not 'as crow flies', please?
By Julie on 22nd December 2020

Someone below struggling with formatting for bulk. If you have the 2 sets in Excel in column A and B, then in C1 add =A1&","&B1 then fill down. Copy column C into website. All works smoothly for me.

Unfathomable formatting of postcodes for batch processing - going to see if I can find another tool to do this, I've run out of combinations to reformat just one line

Great system, could you look at increasing the number of items that can be uploaded from 200 to 1000

Hi, this shows different results compared to google maps for crow flies distance (using measure distance option). I am confused which one is accurate, google map or this one. Any idea why it would show different results
