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.
A goal in the 74th minute by substitute Aleksandr Prijovic led Serbia to a 1-0 triumph over visiting Georgia, boosting their point total to 21, two more than Ireland, who nailed down second place with a 1-0 away win against a Wales squad missing the injured Gareth Bale.
It was the first home loss for Wales in 11 matches.
Monday's Group G matches offered little in the way of drama, as Spain and Italy started the day in possession of the top two spots.
La Roja, with a squad made up mostly of subs, beat Israel 1-0 in Jerusalem, while the Azzurri won by the same margin against Albania.
