The question of whether or not proton decay conserves baryon minus lepton number is studied. We argue that observation of B - L violation would indicate the existence of physical structure in the mass scale between MW ≃ 102 GeV and MX ≃ 1016 GeV, contrary to the usual supposition about grand unification.
