Upon the outbreak of a conflict and in all cases of occupation, each of the Parties to the conflict shall institute an official Information Bureau for prisoners of war who are in its power. Neutral or non-belligerent Powers who may have received within their territory persons belonging to one of the categories referred to in Article 4, shall take the same action with respect to such persons. The Power concerned shall ensure that the Prisoners of War Information Bureau is provided with the necessary accommodation, equipment and staff to ensure its efficient working. It shall be at liberty to employ prisoners of war in such a Bureau under the conditions laid down in the Section of the present Convention dealing with work by prisoners of war.

Within the shortest possible period, each of the Parties to the conflict shall give its Bureau the information referred to in the fourth, fifth and sixth paragraphs of this Article regarding any enemy person belonging to one of the categories referred to in Article 4, who has fallen into its power.

The Bureau shall immediately forward such information by the most rapid means to the Powers concerned, through the intermediary of the Protecting Powers and likewise of the Central Agency provided for in Article 123.

This information shall make it possible quickly to advise the next of kin concerned. Subject to the provisions of Article 17, the information shall include, in so far as available to the Information Bureau, in respect of each prisoner of war, his surname, first names, rank, army, regimental, personal or serial number, place and full date of birth, indication of the Power on which he depends, first name of the father and maiden name of the mother, name and address of the person to be informed and the address to which correspondence for the prisoner may be sent.

The Information Bureau shall receive from the various departments concerned information regarding transfers, releases, repatriations, escapes, admissions to hospital, and deaths, and shall transmit such information in the manner described in the third paragraph above.

Likewise, information regarding the state of health of prisoners of war who are seriously ill or seriously wounded shall be supplied regularly, every week if possible.

The Information Bureau shall also be responsible for replying to all enquiries sent to it concerning prisoners of war, including those who have died in captivity; it will make any enquiries necessary to obtain the information which is asked for if this is not in its possession.

All written communications made by the Bureau shall be authenticated by a signature or a seal.

The Information Bureau shall furthermore be charged with collecting all personal valuables, including sums in currencies other than that of the Detaining Power and documents of importance to the next of kin, left by prisoners of war who have been repatriated or released, or who have escaped or died, and shall forward the said valuables to the Powers concerned. Such articles shall be sent by the Bureau in sealed packets which shall be accompanied by statements giving clear and full particulars of the identity of the person to whom the articles belonged, and by a complete list of the contents of the parcel. Other personal effects of such prisoners of war shall be transmitted under arrangements agreed upon between the Parties to the conflict concerned.
