What must the national member federation indicate when requesting a letter of clearance?

When a national member federation requests a letter of clearance, it is essential to indicate the name, nationality, and license number of the agent representing the player. This information is critical as it helps to verify the legitimacy and credentials of the agent involved in the player's transfer process. It ensures that the agent is registered and accredited by the appropriate basketball governing bodies, such as FIBA, thereby maintaining the integrity of the player transfer system.

The other options do not directly pertain to the requirements for a letter of clearance. While details like the player's height and weight, past performance statistics, and proposed contract details with the new club may be relevant in discussions of a player's profile, they are not essential elements that must be included in the request for a letter of clearance. The focus lies primarily on the agent's identification to facilitate the transfer process properly.
