Abstract: Technologies are described related to the delivery of items utilizing electronic locker arrangements. Systems described herein coordinate and manage the delivery of items by large numbers of couriers using a network of electronic locker arrangements. Implementations are described corresponding to couriers delivering items between electronic locker arrangements without the use of a distribution hub. In certain implementations, delivery of items is consolidated to electronic locker arrangements that include a number of lockers. This can increase security and privacy by eliminating the need to know a recipient's address in order to deliver an item. The system can notify a recipient that an item is available for pickup at a nearby electronic locker arrangement. Authentication techniques are described to enable the secure access to electronic locker arrangements that are storing items for delivery.
