After the group stage concludes on October 10, eight runners-up will be drawn into four pairings, with two-legged play-off ties set for November 9-11 and 12-14, 2017.
The away goals rule will be used to determine a winner of the ties if scores are level after the second leg - whether after 90 minutes or extra time - and four play-off winners will advance to Russia 2018.
But only eight of the nine teams who finish second are eligible for a play-off spot - meaning one team with the least amount of points will miss out.
One of the key factors is that results gained against the bottom-ranked sides in each group do not count in the final play-off standings.
FIFA has confirmed that teams will be seeded for the draw on October 17, with the top four teams according to the FIFA rankings in one pot for and the remaining four in another.
