The draw for the first round (group stage) was held as part of the 2018 FIFA World Cup Preliminary Draw on 25 July 2015, starting 18:00 MSK (UTC+3), at the Konstantinovsky Palace in Strelna, Saint Petersburg, Russia.[1][2] Gibraltar was added to the group after the draw, after becoming FIFA members together with Kosovo in May 2016,[3] and UEFA decided not to put Kosovo in same group as Bosnia and Herzegovina for security reasons.[4][5]
The group winners, Belgium, qualified directly for the 2018 FIFA World Cup. The group runners-up, Greece, advanced to the play-offs as one of the best eight runners-up.
Russia was initially partnered with the five-team Group H, which enabled the 2018 World Cup hosts to play centralised friendlies against these countries on their "spare" match dates.[6] These friendlies would not have counted in the qualifying group standings. However, after the group was later expanded to include Gibraltar, these friendly matches were cancelled.
The fixture list prior to the inclusion of Gibraltar was confirmed by UEFA on 26 July 2015, the day following the draw.[1][8] Times are CET/CEST,[note 1] as listed by UEFA (local times are in parentheses).[9]
A player was automatically suspended for the next match for the following offences:[11]

The following suspensions were served during the qualifying matches:
^Bosnia and Herzegovina were sanctioned by FIFA to play one home match (against Belgium on 7 October 2017) away from Bilino Polje Stadium, Zenica due to a series of incidents during their home match against Greece.[10]
