Mandated by Article 102 of the UN Charter and the General Assembly Regulations to give effect to Article 102, the UNTS includes the texts of treaties in their authentic language(s) along with translations into English and French, as appropriate. All integral elements of treaties, such as various types of maps, charts, sketches of boundary delimitation, annexes, protocols, exchanges of letters, etc. are also published.
Registration numbers for instruments included in the UNTS consist of a Roman numeral and an Arabic numeral, joined by a colon (i.e., I:54321;II:965). The Roman numeral indicates treaties and international agreements registered with the Secretariat; Roman numeral II indicates treaties and international agreements filed and recorded by the Secretariat.
