Number 69 has not been officially or formally banned by league-wide legislation across the National Hockey League, meaning players are technically permitted to select it. However, the number is exceptionally rare and virtually never seen on the ice due to unwritten hockey traditions, cultural connotations, and potential concerns regarding distraction or locker room decorum. While the NHL office does not maintain a strict rule prohibiting specific jersey digits outside of league-retired numbers, individual team management, equipment managers, and coaching staffs occasionally discourage players from selecting certain provocative numbers, ensuring that players naturally gravitate toward traditional hockey digits ranging from 1 to 98.
