Jabarkan Grup dari Kualifikasi Piala Dunia FIFA 2018 – UEFA

Pengundian untuk babak kedua (play-off) dilaksanakan pada 17 Oktober 2017 pukul 14.00 CEST (UTC+2), at the FIFA headquarters in Zürich, Switzerland. The eight teams were seeded by FIFA World Rankings published on 16 October 2017, rather than qualifying record, with the top four teams in Pot 1, and the remaining four teams in Pot 2. It so happened that the top four teams by qualifying record were the same as the top four by FIFA World Ranking. Teams from Pot 1 played teams from Pot 2 on a home and away basis, with the order of legs decided by draw.
