Treaties possess different names: international conventions, international agreements, covenants, final acts, charters, memorandums of understandings (MOUs), protocols, pacts, accords, and constitutions for international organizations.
- Usually these different names have no legal significance in international law (see next section for the difference in U.S. law).
- Treaties may be bilateral (two parties) or multilateral (between several parties) and a treaty is usually only binding on the parties to the agreement.
- An agreement "enters into force" when the terms for entry into force as specified in the agreement are met. Bilateral treaties usually enter into force when both parties agree to be bound as of a certain date.

Research Tip from Duke International Legal Research Tutorial
U.S. treaties and agreements are available from many different sources. To locate the treaty you need, remember:
- these sources differ
- consult more than one of the sources
- Call the Department of State's Office of Treaty Affairs at (202) 647-1345 for up-to-date treaty information.
- Or, if you are looking for a very recent treaty which has been submitted to the Senate for advice and consent, contact the Senate Committee on Foreign Relations at (202) 224-4651.
