HOW IT WORKS
How the Distance Between UK Postcodes works
Resolve postcode centres
Each postcode is matched to its published latitude and longitude.
Calculate straight-line distance
The tool uses the great-circle distance between those coordinates and reports miles and kilometres.
COMMON QUESTIONS
Frequently asked questions
Is this driving distance?
No. It is straight-line distance between postcode-centre coordinates, not road distance or travel time.
Are the coordinates exact addresses?
No. Postcode coordinates represent postcode geography and should not be treated as a private property location.
Can I use partial postcodes?
No. This tool requires two full UK postcodes.
Where does the postcode data come from?
The live lookup uses Postcodes.io open postcode data.
