The draw determines each tie in the round of 16 (numbered 1 through 8) between a team from Pot 1 and a team from Pot 2, each containing eight teams. The "Bracket Position Pots" (Pot A and Pot B) contains the bracket positions numbered 1 through 8 corresponding to each tie. The teams from Pot 1 are assigned a bracket position from Pot A and the teams from Pot 2 are assigned a bracket position from Pot B. Teams from the same association cannot be drawn against each other in the round of 16 except for "wildcard" teams which replace a team from another association.
The seeding of teams are based on the CONCACAF Club Index. The CONCACAF Club Index, instead of ranking each team, is based on the on-field performance of the teams that have occupied the respective qualifying slots in the previous five editions of the CONCACAF Champions League. To determine the total points awarded to a slot in any single edition of the CONCACAF Champions League, CONCACAF uses the following formula:
Points per

The slots are assigned by the following rules:
For teams from North America, nine teams qualify based on criteria set by their association (e.g., tournament champions, runners-up, cup champions), resulting in an assigned slot (e.g., MEX1, MEX2) for each team. If a team from Canada qualify through the CONCACAF League, they are ranked within their association, resulting in an assigned slot (i.e., CAN2) for them.
For teams from Central America, they qualify through the CONCACAF League, and are ranked per association by their CONCACAF League ranking, resulting in an assigned slot (e.g., CRC1, CRC2) for each team.
For teams from the Caribbean, the CONCACAF Caribbean Club Championship champions are assigned the Caribbean champion slot (i.e., CCC1). If teams from the Caribbean qualify through the CONCACAF League, they are ranked per association by their CONCACAF League ranking, resulting in an assigned slot (e.g., JAM1, SUR1) for each team.
The 16 teams are distributed in the pots as follows:
