The boundaries have been created from the most accurate Ordnance Survey location data which
have a Positional Quality Indicator indicating that the contributing grid references are
“Within the building of the matched address closest to the postcode mean determined
automatically by Ordnance Survey." The result is a set of boundaries that will fall
correctly between the contributing Postcode locations. It should be noted that as these
boundaries are created programmatically they will not accurately follow natural or man-made
bounding features such as rivers, canals or road networks. An example of the accuracy of the
data is shown in the images on the
boundaries product specification document.
