The draw for the final qualifiers takes place on Tuesday and will determine the pairings of the four matches, with those ranked highest avoiding each other.
Northern Ireland (23rd), Sweden (25th), Republic of Ireland (26th) and Greece (47th) go into the draw unseeded, with the latter looking to become the first UEFA nation to reach three successive World Cups via the play-offs.
The first legs will take place between November 9 and 11, with the return matches scheduled from November 12 to 14.
