Systems and methods are provided for distributing parcels to users by way of unmanned devices. One computer-implemented method includes actuating a locking mechanism of a compartment of the unmanned device to secure a parcel within the compartment and receiving, from a parcel provider associated with delivering the parcel to a user, a delivery location and a hashed key for the parcel. The method then also includes, at the delivery location of the parcel: capturing an image of a computer-readable indicia representative of a hashed key from the user; determining that the hashed key from the user and the hashed key received from the parcel provider match; and when the hashed keys match, actuating the locking mechanism associated with the compartment of the unmanned device to enable the user to access the compartment and retrieve the parcel.
