In the gold medal game, Okafor made all of his field goal attempts posting 18 points and 14 rebounds. For the tournament, his 46 rebounds over 5 games ranked him second on the United States team (to Aaron Gordon) and third at the Championships in rebounding.  He was a member of USA Basketball's 12-man Team USA at the 2012 FIBA Under-17 World Championship with Parker and Nunn again. His listed height was 6 feet 11 inches (2.11 m). At a two-game four-team preliminary exhibition tournament in Las Palmas, Canary Islands the week before the championship began, he was named tournament MVP. He was also named MVP of the 2012 FIBA Under-17 World Championship for the gold medal-winning United States team. Okafor posted 17 points and 8 rebounds in the gold medal game.

On May 21, 2013, USA Basketball announced the roster of 24 players, including Okafor, who had accepted invitations to the June 14-19, 2013, USA Basketball Men's U19 World Championship team training camp. The camp was used to select the 12-man team for the June 27 - July 7, 2013 FIBA Under-19 World Championship in Czech Republic. Okafor made the final roster that was announced on June 18. The team won the gold medal and Okafor made the All-Tournament team along with teammate and tournament MVP Gordon. He led the tournament with 77% field goal percentage, and he was the only player on the all tournament team who would return to high school. However, coaches Billy Donovan and Shaka Smart told him his weak link was his conditioning.
