*Only one category per player may be entered among those held on the same day. Categories held on different days can be combined, even within the same event (e.g., Men's Doubles 50+ on January 22 and Men's Doubles 35+ on January 24).
*"+" means "and over" (e.g., 50+ means 50 and over). However, the 19+ Open has no lower age limit, so players 18 and under may also enter (players under 18 need written consent from a parent or guardian). Age is as of the first day of the event (January 21, 2027).
*DUPR under 3.5 is a level-based category not divided by age group (held for the three doubles events only: men's, women's, and mixed). Both players in a pair must have a DUPR rating (doubles) under 3.5. Players with no rating (NR) may also enter.
