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.

Uses of This Postcode Tool

One used to be able to see the road distance between postcodes but this is no longer possible as several people have noticed. Could there be a problem with the latest update?

By Alpesh on 16th September 2024

Great effort! Would be really useful if road travel distance can be shown for bulk processing.
On 27th March 2024

Hi, nice tool! I have a list of from/to postcodes for which i'd like to bulk process and get the road distance. The result returns the crow flies distance only. Any way of getting the road distance?
By PT on 12th March 2024

The location on the map is not correct for the postal code GL2 5LZ.
By B Hanks on 18th February 2024

Useful if the distances were produced as standalone data, would help copy and paste across into Excel

Its a CSV list thats displayed in the output textbox.

How do I access the CSV file please for bulk processing?
By Gwynneth on 26th January 2024

The results for the Bulk processing are as the crow flies only, the distance by Land Transport would be great
By JimG on 24th January 2024

Phil, the distances are appended in the text box that you type in to.
On 23rd January 2024

I have run the report it says "Processing Complete. Units are in miles" where is the file once its completed?
By Phil C on 22nd January 2024

Brilliant App - Thank you Please could the Bulk processor provide the land transport distance and time results too - would be really helpful for people working in rural areas
By Dr A Sloper on 20th December 2023

Excellent little app - I have used it for finding distances between football clubs for my spreadsheet results predictor - would be good if it had the option of by road for multiple postcodes also the 200 limit is a little restrictive
By David on 27th November 2023

Would it be possible to add the option to select 'Distance by Land Transport' to the Bulk Processing section?
