Systems and methods for re-routing parcels being delivered to attended delivery/pickup locations that have no capacity and/or ability to take delivery of the parcels. In various embodiments, in response to determining that the attended delivery/pickup location doesn't have sufficient capacity and/or ability to accept delivery of the parcel, the system is configured to: (1) re-route the parcel to a different location; or (2) hold the parcel for later delivery. In some embodiments, the system is configured to determine an appropriate response to determining that the attended delivery/pickup location cannot accept delivery of the parcel substantially automatically. In other embodiments, the system is configured to provide the parcel recipient with one or more re-routing options.
