Out-of-home delivery is a parcel delivery model in which shipments are not delivered directly to the recipient's address but instead deposited at an accessible third-party location for later collection. This model includes PUDO points, smart locker networks, parcel shops, and carrier-operated delivery hubs. Out-of-home delivery solves one of the key inefficiencies of home delivery: the absence of the recipient at the time of the delivery attempt. By offering collection at a location of the recipient's choice and at a time that suits them, it reduces failed deliveries, cuts redelivery costs, and lowers the carbon footprint of the last mile. Columat's smart locker solutions form a core part of out-of-home delivery infrastructure for urban logistics operators, retailers, and corporate campuses. Related concepts include PUDO points and last mile delivery.
