Depositary record

United Nations Treaty Collection

Accession is not ratification. A state accedes to a treaty it never signed, so there is no signature date to show and none is missing. The two are often written as though interchangeable; the record does not treat them that way, so neither does this page.

Where this sits

• 45 in order of becoming party
• 75 states bound in total
• New treaty adopted

Order is by the date the depositary records, and states that became bound on the same day share a position — eleven states became party to the Charter on 24 October 1945 and none of them was eleventh.
