How are the vest numbered in International Basketball Competition?

Question

Accepted Answer

The correct option is (3):
The range 4 to 15 was, for many decades, the standard and mandatory numbering system for player vests in major international basketball competitions governed by FIBA (Fédération Internationale de Basketball Amateur). This historical rule ensured uniformity and avoided confusion, as numbers 1, 2, and 3 were traditionally not permitted for players. The lower single digits (1, 2, 3) were often reserved for technical use by referees and table officials for signaling fouls and other calls, making their use as player numbers on the court problematic for accurate scoring and officiating. Therefore, the starting number for players was set at 4, and the full mandatory range extended up to 15 to accommodate a full 12-player roster plus a few reserves or positional options. Although FIBA changed its rules around 2015 to allow a much broader range (0, 00, and 1 to 99), this question from the 2016 exam reflects the deeply established historical convention.

The incorrect option is (1):
The option 1 to 10 is incorrect because it is too restrictive and does not align with the historical FIBA convention for player numbering. While numbers 4 to 10 are a subset of the correct range, excluding 11, 12, 13, 14, and 15 would not allow for a full squad of players to be clearly and traditionally numbered for international tournaments. The traditional system was designed to accommodate the entire team roster, which, with substitutes, typically required numbers up to 15.

The incorrect option is (2):
The option 3 to 15 is incorrect because, under the long-standing FIBA convention that this question is based on, the number 3 was traditionally not permitted for players. The rule was specifically established to start the allowed player numbers at 4. Including 3 would violate the system put in place to avoid conflicting with the referee's hand signals, as numbers 1, 2, and 3 are vital signals in officiating. The established practice was to begin player numbering outside this conflict range.

The incorrect option is (4):
The option 1 to 15 is incorrect as it includes numbers 1, 2, and 3, which were strictly prohibited for players under the traditional FIBA rules. This rule, beginning with 4, was a hallmark of international basketball for decades. The reason for excluding these lower numbers was a matter of practical officiating, as single-digit numbers 1, 2, and 3 are used by officials to visually signal various violations and free throw attempts, making it confusing to have players wear them.
