Tams will be paired geographically for the first four rounds and beginning with the round 16 a geographically based random draw will take place to determine the matchups and set a fixed bracket to the final four rounds.
The Open Division teams (including clubs from the PDL and NPSL as well as those advancing from local qualifying) include La Maquina, which advanced all the way to the fourth round of the 2016 competition, where it fell to the LA Galaxy in overtime. Also still alive is LA Wolves FC, now coached by Eric Wynalda.
One local qualifier, Minneapolis City SC, was declared ineligible for switching leagues (from the Premier League of America to NPSL) during the midst of its 2017 Open Cup campaign in violation of competition regulations.
