Downloads – Post Office Numbers from 1844
The files linked to on this page comprise the text of John Parmenter and Ken Smith's detailed listing of numbers allocated to post offices in England and Wales (including Post Offices Abroad which were allocated numbers in this series), and the separate series of numbers allocated to London offices. They provide the most detailed treatment available concerning which numbers were used in which offices and when.
See the Introduction document for details.
A scanned copy of the 1962 official listing of numbers has also been included for reference.
