Article 71

Prisoners of war shall be allowed to send and receive letters and cards. If the Detaining Power deems it necessary to limit the number of letters and cards sent by each prisoner of war, the said number shall not be less than two letters and four cards monthly, exclusive of the capture cards provided for in Article 70, and conforming as closely as possible to the models annexed to the present Convention. Further limitations may be imposed only if the Protecting Power is satisfied that it would be in the interests of the prisoners of war concerned to do so owing to difficulties of translation caused by the Detaining Power's inability to find sufficient qualified linguists to carry out the necessary censorship. If limitations must be placed on the correspondence addressed to prisoners of war, they may be ordered only by the Power on which the prisoners depend, possibly at the request of the Detaining Power. Such letters and cards must be conveyed by the most rapid method at the disposal of the Detaining Power; they may not be delayed or retained for disciplinary reasons.

Prisoners of war who have been without news for a long period, or who are unable to receive news from their next of kin or to give them news by the ordinary postal route, as well as those who are at a great distance from their homes, shall be permitted to send telegrams, the fees being charged against the prisoners of war's accounts with the Detaining Power or paid in the currency at their disposal. They shall likewise benefit by this measure in cases of urgency.

As a general rule, the correspondence of prisoners of war shall be written in their native language. The Parties to the conflict may allow correspondence in other languages.

Sacks containing prisoner of war mail must be securely sealed and labelled so as clearly to indicate their contents, and must be addressed to offices of destination.
