* The United Nations has two non-member observer states: the Holy See (which represents Vatican City) and the State of Palestine. Observer states can participate in General Assembly debates and view documents but cannot vote on resolutions. Some country counters I have met in my journeys include these two countires in their list and bring the total to 195.

Consequently, I have visited a total of 157/193 United Nations member countries or 159/195.
