North Korea qualified for its first World Cup finals since 1966 when it drew with Saudi Arabia 0-0 on Wednesday.
North Korea joined Australia, Japan and South Korea as Asia's automatic qualifiers.
Saudi Arabia and Bahrain, the third-place finishers in the two Asian groups, will meet in a playoff.
The winner of that will then face Oceania champion New Zealand for a berth in next year's World Cup in South Africa.
