Date

1936-1967

Description

This series contains records of the Communication Department of the Foreign Office (1936-1964) and the Diplomatic Service Administration Office (1965-1968), dealing with all communication matters between London and Britain's overseas embassy and consular posts in foreign countries and, from 1965, in the Commonwealth and with overseas trade missions.

Arrangement
Arrangement

From 1947, the Communications Department had the departmental code 'Y'. From 1947 to 1949, records were registered by subject under the numerical code 650 (where, for example, 650 = Communications, General, and 659 = Diplomatic Wireless). From 1950, records were registered according to the new Foreign Office filing system using the departmental letter code and subject letter, as shown:

  • Y - Communications, general
  • YB - Bag services
  • YC - Bag and contents
  • YE - Diplomatic wireless, engineers
  • YP - Diplomatic wireless, telephones
  • YT - Telegrams
  • YW - Diplomatic wireless

In 1965, the Communications Department was merged with its counter-part from the Commonwealth Relations Office to form a new Communications Department in the Diplomatic Service Administration Office, and the department code used in registering the files was changed from 'Y' to 'DSY'. A new subject letter was created at this time for the Communications Directorate, DSYH.
