A parcel delivery locker has a body portion formed by four panels that are joined to each other along hinge joints at their vertical edges. The hinges joints allow the body portion to be alternatively configured into a stack for shipping, or as a box for use in receiving and containing parcels. A lid is joined to the body portion during assembly and has an electronically controlled locking mechanism that can be wirelessly controlled to lock or unlock. A floor portion is coupled to the four panels as well.
