Jersey number sixty-nine is not explicitly or officially banned by rulebook text in the National Hockey League, but it is effectively prohibited through traditional unwritten hockey culture, locker room etiquette, and equipment management norms. While the league permits players to select numbers ranging anywhere from 1 up to 98, players almost universally avoid choosing sixty-nine due to its prominent juvenile pop-culture connotations and the inevitable distraction it would bring inside a professional dressing room. Team management, veteran leaders, and equipment managers strongly discourage rookies from selecting numbers that invite unnecessary media circus or childish jokes, ensuring that traditional, professional numbering conventions remain strictly respected across every franchise in the league.
