Among the sixteen teams participating in the Copa América Centenario, six of them were from CONCACAF. Four of the six CONCACAF representative teams had already qualified prior to the 2015 CONCACAF Gold Cup:
The two remaining places were determined by a play-off system which itself was determined by the outcome of the 2015 Gold Cup. The system was as follows:[3][4]
If a team other than the four teams already qualified won the 2015 Gold Cup, the Gold Cup winners would qualify for the Copa América Centenario, while the two highest-ranked teams outside of those already qualified for the Copa América Centenario from the 2015 Gold Cup would compete in a play-off.
If a team that had already qualified won the 2015 Gold Cup, the four highest-ranked teams outside of those already qualified for the Copa América Centenario from the 2015 CONCACAF Gold Cup would compete in two play-offs, with the highest-ranked team facing the fourth highest-ranked team, and the second highest-ranked team facing the third highest-ranked team.
Since the winners of the 2015 CONCACAF Gold Cup (Mexico) had already qualified for the Copa América Centenario, a total of four teams played in the qualifying play-offs.

Note: Per statistical convention in football, matches decided in extra time are counted as wins and losses, while matches decided by penalty shoot-out are counted as draws.
Seeding
The four teams were seeded based on the Gold Cup results:
It was reported that each tie would be played over two legs in October 2015.[5] However, on 29 October 2015 CONCACAF confirmed that the ties would be played as a single-match doubleheader hosted at the Estadio Rommel Fernández in Panama City, Panama on 8 January 2016, with Panama earning the hosting rights as the highest-seeded team.[1]
