osreference | OS Reference. e.g PE132QL ="TF4630009100" This is our national coordinate system for topographic mapping. It is used for Ordnance Survey mapping at all scales, and for many private topographic surveys. The OSGB36 part of the name refers to the geodetic datum (system of latitude and longitude) used, and the National Grid part refers to the map projection and grid referencing convention for eastings and northings |

mailsort | Is a unique 5-digit numeric codes used internally by Royal Mail to route mailbags. They are also used by external customers with Mailsort contracts, which is why they are present in the data. |
The fields of main interest are:
Easting and Northings, the OS easting of the outcode, distance in metres due east from the south west of the UK.
Longitude and Latitude, using the WGS84 geodetic datum, used for mapping, and calculating distance between two postcodes
OS reference, OS representation of the location
Postcode, returned when searching by OS Ref, or Longitude/Latitude
This data is available through our programming interfaces only, and can be retrieved by Postcode, OS Ref, or Longitude/Latitude. These interfaces also contain functions for working out the distance between two postcodes.
Postcodes, which relate to PO Boxes, are not included in this file, because they DO NOT have a location.
The accuracy of the Longitude/Latitude varies. Can be between 10-150 m
