The two counts differ. Organization of American States publishes 35 members; 34 resolved against the 193 states this site has checked. Sometimes that is a disagreement about what counts as a member state — a non-UN state, a territory, a suspended member — and sometimes the compiled source lacks a current statement for a real one. Either way the gap is shown rather than smoothed over, because a table that quietly shows one number cannot be checked against the other.
Member states
Ordered by accession. A state with no recorded date is listed last rather than given one.
A joining date is the one the source records, which may be the day a treaty was signed or the day it took effect. States that joined together can therefore differ by months here.
