Systems, methods, and media are provided herein for synchronizing delivery between two or more shipments, each shipment associated with one or more items. For example, a Global Positioning System (GPS) device detects a geocode for a first serviceable point, the geocode corresponding to a latitude and longitude coordinate (and an altitude in some aspects). A record may be stored at a database, the record comprising shipment data for a shipment of an item and the geocode for the first serviceable point. Another shipment may be determined to be within a range of a time associated with the shipment data for the shipment. The other shipment may also have a second serviceable point within a threshold distance of the first serviceable point. Based on the range of time and the threshold distance, an indication (that the shipments are available for synchronized delivery) may be provided.
