Coverage

The Postcode Database covers the United Kingdom.

Supply Format

The data is supplied as a series of Comma Separated Variable (CSV) delimited text files, 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 some files, older versions of Excel (pre 2010) may not fully open the files supplied as these older versions of Excel limit any opened file size to the first 65,000 rows / records.

Delivery

The Postcode Database 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 Database 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.
