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 delivering items to an individual via different electronic locker arrangements as the location of the individual changes. The systems can track the location of individuals and as requests to deliver items are received by the systems, the current location of the individuals can be used to determine an electronic locker arrangement to store items for the individuals until the items are picked up. The systems can generate identifiers that uniquely correspond to individuals and their various locations. In these situations, the identifiers can be used by the individuals or by others to have items delivered to the individuals via electronic locker arrangements.
