What is the maximum number of national member federations a player can be licensed with at the same time?

A player can only be licensed with one national member federation at a time. This rule is in place to ensure that a player's eligibility and representation are clear and unambiguous in international competitions. When a player is registered with a national federation, they commit to representing that federation in competitions governed by FIBA.

Being limited to a single federation helps maintain the integrity of international basketball and prevents any potential conflicts or disputes over player eligibility. If a player wishes to change their affiliation to another federation, usually, certain procedures must be followed, such as waiting periods or the fulfillment of contractual obligations with the original federation.

The other choices imply that players could hold dual or multiple licenses, which would complicate regulations and lead to issues in representing national teams in international play. Thus, the structure of FIBA regulations enforces this single-licensing policy to streamline the governance of international basketball.
