Treaties and International Acts Series (TIAS)

The Office of Treaty Affairs compiles and publishes online the texts of treaties and international agreements to which the United States is a party through the Treaties and International Acts Series (TIAS).  TIAS has been published exclusively in electronic form on the Office of Treaty Affairs website since 2006. Publication of treaties and agreements in TIAS is governed by 1 U.S.C. § 112a and 22 CFR 181.8, in accordance with these provisions:

  • The Department publishes the texts of treaties and other international agreements within 180 days after the date on which the treaty or agreement enters into force.  For information on subscribing to receive notifications of newly published agreements, click here.
  • TIAS serves as “legal evidence of the treaties, international agreements other than treaties, and proclamations by the President of such treaties and agreements, therein contained, in all the courts of the United States, the several States, and the Territories and insular possessions of the United States.”
  • Certain categories of agreements are not published in TIAS, in accordance with 1 U.S.C. § 112a (b) and 22 CFR 181.8.

Finding Older Agreement Texts

No single source contains a comprehensive collection of all treaties and international agreements, so it may be necessary to consult more than one source to find the text of a particular treaty or agreement.  Aside from responding to requests made under the Freedom of Information Act, the Department of State does not provide the texts of treaties or international agreements in response to individual inquiries. For guidance on locating agreement texts, please visit the Finding Agreements page.
