Geneva Convention (IV): Relative to the Protection of Civilian Persons, Part III, Section 5

Upon the outbreak of a conflict and in all cases of occupation, each of the Parties to the conflict shall establish an official Information Bureau responsible for receiving and transmitting information in respect of the protected persons who are in its power.

Each of the Parties to the conflict shall, within the shortest possible period, give its Bureau information of any measure taken by it concerning any protected persons who are kept in custody for more than two weeks, who are subjected to assigned residence or who are interned. It shall, furthermore, require its various departments concerned with such matters to provide the aforesaid Bureau promptly with information concerning all changes pertaining to these protected persons, as, for example, transfers, release, repatriations, escapes, admittances to hospitals, births and deaths.

Each national Bureau shall immediately forward information concerning protected persons by the most rapid means to the Powers of whom the aforesaid persons are nationals, or to Powers in whose territory they resided, through the intermediary of the Protecting Powers and likewise through the Central Agency provided for in Article 140. The Bureaux shall also reply to all enquiries which may be received regarding protected persons.

Information Bureaux shall transmit information concerning a protected person unless its transmission might be detrimental to the person concerned or to his or her relatives. Even in such a case, the information may not be withheld from the Central Agency which, upon being notified of the circumstances, will take the necessary precautions indicated in Article 140.

All communications in writing made by any Bureau shall be authenticated by a signature or a seal.

The information received by the national Bureau and transmitted by it shall be of such a character as to make it possible to identify the protected person exactly and to advise his next of kin quickly. The information in respect of each person shall include at least his surname, first names, place and date of birth, nationality, last residence and distinguishing characteristics, the first name of the father and the maiden name of the mother, the date, place and nature of the action taken with regard to the individual, the address at which correspondence may be sent to him and the name and address of the person to be informed.

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

Each national Information Bureau shall, furthermore, be responsible for collecting all personal valuables left by protected persons mentioned in Article 136, in particular those who have been repatriated or released, or who have escaped or died; it shall forward the said valuables to those concerned, either direct, or, if necessary, through the Central Agency. Such articles shall be sent by the Bureau in sealed packets which shall be accompanied by statements giving clear and full identity particulars of the person to whom the articles belonged, and by a complete list of the contents of the parcel. Detailed records shall be maintained of the receipt and despatch of all such valuables.

A Central Information Agency for protected persons, in particular for internees, shall be created in a neutral country. The International Committee of the Red Cross shall, if it deems necessary, propose to the Powers concerned the organization of such an Agency, which may be the same as that provided for in Article 123 of the Geneva Convention relative to the Treatment of Prisoners of War of August 12, 1949.

The function of the Agency shall be to collect all information of the type set forth in Article 136 which it may obtain through official or private channels and to transmit it as rapidly as possible to the countries of origin or of residence of the persons concerned, except in cases where such transmissions might be detrimental to the persons whom the said information concerns, or to their relatives. It shall receive from the Parties to the conflict all reasonable facilities for effecting such transmissions.

The High Contracting Parties, and in particular those whose nationals benefit by the services of the Central Agency, are requested to give the said Agency the financial aid it may require.

The foregoing provisions shall in no way be interpreted as restricting the humanitarian activities of the International Committee of the Red Cross and of the relief Societies described in Article 142.

The national Information Bureaux and the Central Information Agency shall enjoy free postage for all mail, likewise the exemptions provided for in Article 110, and further, so far as possible, exemption from telegraphic charges or, at least, greatly reduced rates.
