The formal designation is “State Party to the Rome Statute,” the treaty that established the Court. The Statute entered into force on 1 July 2002. Treaty participation is separate from membership in the United Nations, and being a State Party does not by itself mean that a country is the subject of an ICC case. See the ICC roster and the Rome Statute.

Have any countries withdrawn?
A government’s announcement or initial steps toward withdrawal do not necessarily mean that its membership has ended. Under Article 127 of the Rome Statute, withdrawal requires written notification to the UN Secretary-General and normally takes effect one year after the notification is received, unless a later date is specified. The article also preserves obligations accrued while the state was a party, certain cooperation duties, and consideration of matters already before the Court.
Rank #2
Article 127(2) states: “A State shall not be discharged, by reason of its withdrawal, from the obligations arising from this Statute while it was a Party to the Statute, including any financial obligations which may have accrued.”

Naoero (Nauru)
Naoero remains on the ICC’s roster. On 30 September 2026, the Assembly Presidency said it had taken note of Naoero’s steps towards withdrawal, urged it to remain committed as a State Party, and recalled that withdrawal does not erase obligations from the period of membership. Those steps should not be described as an effective exit. See the ICC roster and the Assembly Presidency’s statement on Naoero.
Hungary
Hungary remains a State Party. On 25 May 2026, the Assembly Presidency welcomed the Hungarian government’s decision to discontinue its withdrawal process and remain in the treaty. See the ICC roster and the statement on Hungary.
