Global shipping is complex, involving multiple couriers, customs processes, and last-mile partners. To make this easier to understand, we’ve created a set of open resources that explain parcel routes, tracking number formats, and common delivery statuses. These tools are part of the InstantParcels Knowledge Hub and are freely available for reference.
Learn how universal parcel tracking works, with examples from USPS, UPS, FedEx, and DHL. This document also includes a glossary of common tracking entities and carrier formats.
This sheet connects all public resources, provides UTM-tagged links for reference, and includes two mini-databases:
Carrier code prefixes (USPS, UPS, FedEx, DHL, etc.)
Common tracking statuses (Info Received, In Transit, Out for Delivery)
See how cross-border partners (YunExpress, 4PX, Cainiao) connect with last-mile carriers (USPS, Royal Mail, PostNL, DHL). Explore routes across Asia, Europe, and the US.
A visual overview of how parcels move from Asia to Europe and the US. Includes a step-by-step flow: Detect → Track → Updates → Delivered.
