  We provide a procedure to determine if a given nonlocal operator in a large N
holographic CFT is dual to a local bulk operator on the geometry associated
with a particular code subspace of the CFT. This procedure does not presuppose
knowledge of the bulk geometry. We are able to pick out local operators in a
large region of the bulk, called the "localizable region,"' that can extend
beyond event horizons in certain cases. The method relies heavily on the
quantum-error correcting structure of AdS/CFT and, in particular, on
entanglement wedge reconstruction. As a byproduct of this machinery, we are
able to reconstruct the metric in the localizable region up to a conformal
factor. This suggests a connection between our program and the recent
light-cone cut approach to bulk reconstruction.
