Most tours have separate names for bookeeping purposes. It's much less confusing than just numbers.

Les Miz had the Valjean, Fantine, and Marius companies; Phantom had the Phantom, Christine, and Music Box companies; Rent had Angel, Benny, and Collins.
shesamarshmallow: OK, that makes sense! I've been to one show where they had a BC/EFA speech and auctioned off a "rag doll" (haha), but no mention of a tour.
