Since 1993, the tournament has generally featured 12 teams—all 10 CONMEBOL teams and two additional teams from other confederations. Mexico participated in every tournament between 1993 and 2016, with one additional team drawn from CONCACAF, except for 1999, when AFC team Japan filled out the 12-team roster, and 2019, which featured Japan and Qatar. The 2016 version of the event, Copa América Centenario, featured 16 teams, with six teams from CONCACAF in addition to the 10 from CONMEBOL. Mexico's two runner-up finishes are the highest for a non-CONMEBOL side.
