Every tournament posts its entry list at the venue, on paper, in a place players can reach. The physical posting still matters in a fully digital sport.
The list is a legal document
Entry lists determine who has been accepted, who is on a cut line and who stands as an alternate. Disputes are resolved against the posted version.
Because rankings change and withdrawals occur, the list moves. Posting a timestamped version establishes what was true at a given moment.
Players and their representatives check it directly rather than relying on a notification, since acceptance can turn on a single position.
Alternates need to see movement
An alternate's position changes whenever someone withdraws, and the difference between third and first alternate determines whether they stay in the city.
The posted list is where that movement becomes visible, often before any formal communication reaches the player.
Players waiting on a place therefore visit the board repeatedly, which is why it is placed where players naturally pass.
Sign-in deadlines are enforced against it
Many competitions require a physical sign-in by a stated time. Missing it forfeits a place regardless of ranking or travel difficulty.
The rule exists because organizers must know the field is complete before a draw can be made, and a phone call is a weaker guarantee than a signature.
Enforcement is strict for the same reason it is unpopular. A tolerated exception would make the deadline unenforceable in every future case.
The board is a social space
The entry board is where players, coaches and agents gather, and a good deal of the information around a tournament circulates there rather than officially.
Practice court allocations, order of play drafts and transport schedules are typically posted alongside it for the same reason.
Tournaments that moved everything to an app found that players kept returning to the board, and most now run both.
What the list tells a spectator
For spectators with access, the entry list is the earliest real indication of what a tournament's week will look like.
Late withdrawals appear there before they appear anywhere else, which is why the board attracts an audience beyond the players.
It is a rare piece of a modern event that has not been digitized away, kept because the physical posting does something a notification cannot.
