The final list of up to 20 players per national team had to be submitted to CONCACAF by 1 February 2023, ten days before the opening match of the tournament. All players in the final list had to be chosen from the respective provisional list. In the event that a player on the submitted final list suffered a serious injury or illness up to 24 hours before the kick-off of his team's first match of the tournament, that player could be replaced, provided that it was approved by the CONCACAF Medical Committee. The replacement player must come from the provisional list and will be assigned the shirt number of the replaced player.

CONCACAF published the final lists on 6 February 2023.^[2][3]
