We study the conformal bootstrap for systems of correlators involving nonidentical operators. The constraints of crossing symmetry and unitarity for such mixed correlators can be phrased in the language of semidefinite programming. We apply this formalism to the simplest system of mixed correlators in 3D CFTs with a ℤ_2 global symmetry. For the leading ℤ_2-odd operator σ and ℤ_2-even operator ϵ, we obtain numerical constraints on the allowed dimensions (Δ_σ, Δ_ϵ) assuming that σ and ϵ are the only relevant scalars in the theory. These constraints yield a small closed region in (Δ_σ, Δ_ϵ) space compatible with the known values in the 3D Ising CFT.
