A total of 12 countries submitted a bid to host the tournament by the May 2013 deadline:

The final decision on who would be hosts were made as part of FIFA's Executive Committee meetings in Brazil on 5 December 2013 with Korea Republic being awarded the hosting rights.

Qualified teams
A total of 24 teams qualified for the final tournament. In addition to South Korea who qualified automatically as hosts, the other 23 teams qualified from six separate continental competitions. Starting from 2017, the Oceania Football Confederation received an additional slot (in total two), while UEFA will have five instead of six slots.

The match schedule was announced by FIFA on 23 November 2015.
Former South Korean internationals Ahn Jung-hwan and Park Ji-sung were appointed as the ambassadors of the tournament.
The official emblem, slogan ("Trigger the Fever") and look of the tournament were unveiled on 16 June 2016.

Draw
The draw was held on 15 March 2017, 15:00 KST (UTC+9), at the Suwon Artrium in Suwon, South Korea. Two Argentine players who have won the FIFA U-20 World Cup, Diego Maradona and Pablo Aimar, participated in the draw. Minho Choi from the South Korean idol group SHINee also participated in the draw.

The 24 teams were drawn into six groups of four teams, with hosts South Korea being allocated to position A1. The teams were seeded into their respective pots based on their results in the last five FIFA U-20 World Cups (more recent tournaments weighted more heavily), with bonus points awarded to confederation champions. Teams from the same confederation could not be drawn against each other for the group stage.

Match officials
A total of 22 refereeing trios (a referee and two assistant referees), 5 support referees, and 21 video assistant referees were appointed for the tournament. This was the first FIFA underage tournament which uses the video assistant referee.

Squads

Each team had to name a preliminary squad of 35 players. From the preliminary squad, the team had to name a final squad of 21 players (three of whom must be goalkeepers) by the FIFA deadline. Players in the final squad could be replaced due to serious injury up to 24 hours prior to kickoff of the team's first match. The squads were announced by FIFA on 11 May 2017.

Group stage
The top two teams of each group and the four best third-placed teams advanced to the round of 16.

All times are local, KST (UTC+9).

Tiebreakers
The rankings of teams in each group were determined as follows (regulations Article 17.7):

If two or more teams were equal on the basis of the above three criteria, their rankings were determined by:

Ranking of third-placed teams 
The four best teams among those ranked third are determined as follows (regulations Article 17.8):

Knockout stage 
In the knockout stage, if a match was level at the end of normal playing time, extra time was played (two periods of 15 minutes each) and followed, if necessary, by a penalty shoot-out to determine the winner. However, for the third place match, no extra time was played and the winner was determined by kicks from the penalty mark.

In the round of 16, the four third-placed teams were matched with the winners of groups A, B, C, and D. The specific match-ups involving the third-placed teams depend on which four third-placed teams qualified for the round of 16:

England's previous best result was in 1993 when they finished third, while Venezuela were eliminated in the round of 16 in 2009. This was England's first appearance and victory in the final of a global football tournament since their senior side's 1966 FIFA World Cup victory, ending 51 years of waiting for a global tournament trophy.
