Abstract: A method for a shipment storage apparatus is disclosed. The shipment storage apparatus includes a storage space having a plurality of shipment retainers arranged in it. In the method, access authorization information is obtained. The access authorization information authorises a user to access one or more of the shipment retainers. It is determined whether access by the user to one or more of the shipment retainers can be granted, at least in part on the basis of the obtained access authorization information. Only if it has been determined that access by the user to one or more of the shipment retainers can be granted, access of the user to the storage space is granted, and it is determined whether the user accesses only the one or more of the shipment retainers that the access authorization information authorises the user to access.
