The Royal Mail Archive cares for the archive of Royal Mail Group plc, and Post Office Ltd. It is one of the oldest business archives in the world, and continues to collect and care for the records of the two businesses today.

Records in the Archive are Designated as being of outstanding national importance by the Arts Council, and are on the UNESCO memory of the World UK Register.

The majority of records held are public records and are available for anyone to see onsite, free-of-charge.

The records cover a huge range of business activities and are also a great source of social history. They include documents on postal innovations and designs, employment, transport, publicity, maps, buildings and uniforms, to name a few. The stamp collections include every British stamp issued from 1840 to the present day. The General Post Office (GPO) was one of the biggest employers in the UK and the Archive contains records that are invaluable for family history research.

We have two research guides:

  • Royal Mail Archive – Overview Guide (PDF)
    • This gives an overview of all the records we have in the Archive. The records are divided into POST classes, covering a wide range of subjects.
    • The guide explains what records are held in each POST class. It also has a subject index at the back.
  • Family History Research Guide (PDF)
    • This is a step-by-step guide to discovering your ancestors who worked for the Post Office in the past.
    • At the back there is a list of abbreviations used in the appointment and pension records.
    • For more information please see our family history page.

The guides are long, but you do not have to read every page! Just look at the first few pages to find out how to use each guide. They also are available in the museum’s Archive, along with the best guides of all – our staff. Please contact us if you have any questions.
