Postcode Coordinates

The Postcode Coordinates file provides an accurate grid reference for each of the 1.8 million Postcodes in the UK. The UK currently has over 1.8 million full postcodes (e.g. UB7 0EB) with each postcode representing on average fifteen sites (properties).

Grid references defined by Ordnance Survey's CodePoint locate the Postcode to 1 meter accuracy of the first building within the Postcode.  As Ordnance Survey only provide data for Great Britain (England, Scotland & Wales), X&Y Coordinates for Northern Ireland (Postcodes that begin with postcode area BT) are taken from Royal Mail's PostZon data file. These PostZon X&Y Coordinates are only accurate to approximately one hundred meters and are therefore less accurate than the X&Y Coordinates provided by Ordnance Survey's GB coordinates.

The Postcode Coordinates data is supplied as two separate CSV text files in order to allow opening and viewing of the data in Excel 2007 which overcomes earlier record size restrictions.   The Postcode Coordinates supplied in the file will never be more than three months old and the file comes with free updates throughout the licence period.  When you order the Postcode Coordinates file you will receive a text based list of over 1.8 million UK Postcodes with their appropriate OSGB grid reference and latitude/ longitude (WGS84) co-ordinates.

Postcode Coordinates Applications

The Postcode Coordinates data is ideal for relating Postcodes and address information to their geographic location. The data is therefore essential for analysing:

• The distribution of customers, suppliers or other address-based assets
• The most efficient routes and networks
• Addresses with respect to other geographic features
• Address locations with respect to geographical risks such as flood plains

Fields

• Full Postcode
• Postcode Sector
• Postcode District
• Postcode Area
• PQI
• X Coordinate Grid Reference
• Y Coordinate Grid Reference
• Longitude
• Latitude

Coverage

The Postcode Coordinates data covers the United Kingdom (England, Scotland, Wales and Northern Ireland)

Supply Format

The data is supplied as a Comma Separated Variable (CSV) delimited text file using double quotes by default. This field format will open very easily using almost any software application including but not limited to Excel, Word, Notepad, Access, SQL etc.  Due to the size of the file, older versions of Excel may not be an option as Excel limits any file size to around 65,000 rows / records.

Delivery

The Postcode Coordinates data is by default emailed at the time of order using a secure download link delivery method.  If you require the data supplied in another format then we will be more than happy to accommodate you where reasonable to do so at no extra cost.

Licensing

The Postcode Coordinates list is licensed annually for each user that has access to it.

Updates

The file is updated every three months and free updates will be made available to you so long as your licence remains current.
