In the lead-up to the FIBA Basketball World Cup 2019, the rosters communicated by the National Federations are reflected on the website and the app. These preliminary rosters are pending FIBA approval.

The FIBA-approved list of players will appear on the website with a week to go before the start of the tournament on August 24, 2019. It is the deadline for teams to enter their official player lists.

The 12-man World Cup rosters will be finalized and confirmed during the Technical Meetings to be held on August 29 and August 30, two days before the teams tip off their campaigns.
