The Headquarters are located in Paris. The World Organisation for Animal Health (OIE) is placed under the authority of the Director General of the OIE, appointed by secret ballot by vote of the World Assembly of Delegates.

The Headquarters implement and coordinate activities such as disease information, technical cooperation and scientific activities, which the World Assembly of Delegates has decided upon.

Furthermore, the Headquarters provides the secretariat for the annual General Session of the Assembly, meetings of the Council and the Commissions as well as  technical meetings organised by the OIE; assistance is also given by the Headquarters to the secretariat of regional and specialised conferences. Since 1990 it also has a Documentation Centre of a great scientific value. The Documentation Centre is under the responsibility of the Administration, Logistic and Publications Departement.
