# League Data Type - leagueID [#league-data-type---leagueid]

A `leagueID` uniquely identifies each league. Each league belongs to exactly one `sportID`, but each sport typically has several leagues.

Teams (`teamID`) and players (`playerID`) are defined per league: Arsenal in the Premier League and Arsenal in the Champions League are `ARSENAL_EPL` and `ARSENAL_UCL`.

> League keys are the feed's own vocabulary and are never constructed: `RUGBYLEAGUE_NRLW`, not `NRLW`; `FR_LIGUE_1`, not `LIGUE_1`. Look them up from `/leagues`, which also reports `enabled` per your plan.
