Postal censorship is the inspection or examination of mail, most often by governments. It can include opening, reading and total or selective obliteration of letters and their contents, as well as covers, postcards, parcels and other postal packets. Postal censorship takes place primarily but not exclusively during wartime (even though the nation concerned may not be at war, e.g. Ireland during 1939-1945) and periods of unrest, and occasionally at other times, such as periods of civil disorder or of a state of emergency. Both covert and overt postal censorship have occurred.
Historically, postal censorship is an ancient practice; it is usually linked to espionage and intelligence gathering. Both civilian mail and military mail may be subject to censorship, and often different organisations perform censorship of these types of mail. In 20th century wars the objectives of postal censorship encompassed economic warfare, security and intelligence.

Military mail is not always censored by opening or reading the mail, but this is much more likely during war time and military campaigns. The military postal service is usually separate from civilian mail and is usually totally controlled by the military. However both civilian and military mail can be of interest to military intelligence, which has different requirements from civilian intelligence gathering. During wartime, mail from the front is often opened and offending parts blanked or cut out, and civilian mail may be subject to much the same treatment.
POW and Internee mail
POW and internee mail is also subject to postal censorship, which is permitted under Articles 70 and 71 of the Third Geneva Convention (1929–1949). It is frequently subjected to both military and civil postal censorship because it passes through both postal systems.
Until recent years, the monopoly for carrying civilian mails has usually been vested in governments and this has facilitated their control of postal censorship. The type of information obtained from civilian mail is different from that likely to be found in military mail.
Countries known to have enacted postal censorship
Throughout modern history various governments, usually during times of war, would inspect mail coming into or leaving the country so as to prevent an enemy from corresponding with unfriendly entities within that country. There exist also many examples of prisoner of war mail from these countries which was also inspected or censored. Censored mail can usually be identified by various postmarks, dates, postage stamps and other markings found on the front and reverse side of the cover (envelope). These covers often have an adhesive seal, usually bearing special ID markings, which were applied to reclose and seal the envelope after inspection.
Britain & American colonies
During the years leading up to the American Revolution, the British monarchy in the American colonies manipulated the mail and newspapers sent between the various colonies in an effort to prevent them from being informed and from organizing with each other. Often mail would be outright destroyed.
American Civil War
During the American Civil War both the Union and Confederate governments enacted postal censorship. The number of Union and Confederate soldiers in prisoner of war camps would reach an astonishing one and a half million men. The prison population at the Andersonville Confederate POW camp alone reached 45,000 men by the war's end. Consequently there was much mail sent to and from soldiers held in POW installations. Mail going to or leaving prison camps in the North and South was inspected both before and after delivery. Mail crossing enemy lines was only allowed at two specific locations.
Pre–World War I
In Britain, the General Post Office was formed in 1657, and soon evolved a "Secret Office" for the purpose of intercepting, reading and deciphering coded correspondence from abroad. The existence of the Secret Office was made public in 1742 when it was found that in the preceding 10 years the sum of £45,675 (a huge amount at that time) had been secretly transferred from the Treasury to the General Post Office to fund the censorship activities. In 1782 responsibility for administering the Secret Office was transferred to the Foreign Secretary and it was finally abolished by Lord Palmerston in 1847.
World War I
During the Great War (WWI) Postal censorship occurred in Great Britain, France, Germany and other various countries involved with that war.
Between the wars
Following the end of World War I there were some places where postal censorship was practiced. During 1919 it was operating in Austria, Belgium, Canada, German Weimar Republic and the Soviet Union. Other conflicts during which censorship existed were the Italian occupation of Ethiopia (1935–36) and especially during the Spanish Civil War of 1936-1939.
World War II
During World War II both the Allies and Axis instituted postal censorship of civil mail. The largest organisations were those of the United States, though the United Kingdom employed about 10,000 censor staff while Ireland, a small neutral country, only employed about 160 censors.
British censorship was mainly based in the Littlewoods football pools building in Liverpool with nearly 20 other censor stations around the country. Additionally the British censored colonial and dominion mail at censor stations in the following places:
- Dominions: Australia, Canada, Newfoundland, New Zealand, Southern Rhodesia (not a dominion but supervised by the Dominion office) and Union of South Africa
- Colonies: Aden, Antigua, Ascension Island, Bahamas, Bahrain, Barbados, Bermuda, Ceylon, Cyprus, Dominica, Egypt, Falkland Islands, Fiji, Gambia, Gibraltar, Gilbert and Ellice Islands, Gold Coast, Gibraltar, Granada, British Guiana, British Honduras, Hong Kong, Jamaica, Kenya, Malaya, Malta, Mauritius, Montserrat, New Hebrides, Nigeria, North Borneo, Northern Rhodesia, Nyasaland, Palestine, Penang, St. Helena, St. Lucia, St. Kitts and Nevis, St. Vincent, Sarawak, Seychelles, Sierra Leone, British Solomon Islands, Somalia, Sudan, Tanganyika, Trinidad, Tonga, Uganda, Virgin Islands and Zanzibar,
In the United States censorship was under the control of the Office of Censorship whose staff count rose to 14,462 by February 1943 in the censor stations they opened in New York, Miami, New Orleans, San Antonio, Laredo, Brownsville, El Paso, Nogales, Los Angeles, San Francisco, Seattle, Chicago, San Juan, Charlotte Amalie, Balboa, Cristóbal, David, Panama and Honolulu.
The United States blacklist, known as U.S. Censorship Watch List, contained 16,117 names.
