Technologies are described for determining route proposals for shipment of cargo using unique location identifiers (ULIs). For example, a pickup ULI and a delivery ULI can be received. The pickup ULI and the delivery ULI are in the ULI data structure format defined herein. A first geographic area representing a pickup leg can be determined for shipment of the cargo from the pickup ULI to a first transportation network location and a second geographic area representing a delivery leg can be determined for shipment of the cargo from a second transportation network location to the delivery ULI. The main leg of the shipment occurs between the first transportation network location and the second transportation network location and travels through one or more defined transportation networks. Route proposals can be generated for shipment of the cargo through the pickup leg, main leg, and/or delivery leg.
