League Age 4-7
Players League Age 4–7 may register for any Little League they wish. At these ages, league boundaries do not apply.
Once a player registers at this level, they will remain fully eligible to continue playing in that same league, including All-Stars/International Tournament play, as long as they continue playing every season without interruption and meet all other participation requirements.
League Age 8-16
For players League Age 8–16, Little League International requires that eligibility be based on one of the following:
- Home address: the player lives inside the WSLL boundary
- School enrollment: the player attends an elementary or middle school physically located inside the WSLL boundary
- Uninterrupted participation: the player has played continuously in WSLL since League Age 7
Sibling Exception (2025 Rule)
There is one special exception to these boundary rules:
If a family lives outside the WSLL boundary and has a younger sibling who is League Age 7 or under and registered to play in WSLL, then an older sibling (League Age 8–16) is also allowed to register with WSLL. This rule allows families to keep siblings together in the same league.
