Iceland, the revelation of Euro 2016, made history by qualifying for the World Cup for the first time while Serbia assured themselves of returning to the competition after missing the 2014 edition.
Iceland is home to just 334,000 people, making it the smallest country ever to reach the World Cup, Efe news reported on Monday.
Iceland and Serbia join host-nation Russia, defending champion Germany, Spain, England, Belgium and Poland in the European contingent for the 2018 tournament.
The winners of Groups A and B -- set to be decided on Tuesday -- will also directly qualify, while eight of the nine second-place teams are to face each other next month in a playoff to fill the four remaining European slots.
Gylfi Sigurdsson and Johann Gudmundsson scored as Iceland bested winless Kosovo 2-0 to finish the qualifiers with 22 points, good enough for first place in Group I.
Trailing the Nordic side by two points are Croatia, who got a pair of goals from Andrej Kramaric to win 2-0 at Ukraine to claim second place and a berth in the playoffs.
