Hub-and-spoke is a distribution network design in which a central hub facility (or multiple hubs) connects to many smaller spoke locations. All freight flows through the hub, which consolidates and sorts shipments before dispatching them outward to final destinations. This model, borrowed from airline network design, is the foundational operating model for UPS, FedEx, and most major parcel and LTL carriers.
How Hub-and-Spoke Networks Work
In a parcel carrier’s hub-and-spoke network:
- Local pickup drivers collect packages from shippers and deliver them to the nearest sorting facility (a spoke).
- Packages are sorted at the spoke by destination and loaded onto linehaul trucks or planes heading to the regional or national hub.
- At the hub, packages are sorted again by destination ZIP code or zone and loaded onto outbound linehaul vehicles.
- Packages travel to destination spokes, where local delivery drivers take them to final addresses.
Advantages of Hub-and-Spoke
- Enables nationwide coverage without point-to-point routing between every origin and destination pair
- Consolidates volume at hubs to fill trucks and aircraft efficiently
- Allows carriers to offer consistent, predictable transit times across their network
- Reduces total route mileage compared to direct routing for sparse origin-destination pairs
Hub-and-Spoke and Transit Times
Understanding how a carrier’s hub-and-spoke network operates helps shippers interpret transit time guarantees. Packages generally move fastest when the origin and destination are in the same hub zone. Long-distance shipments that must pass through multiple hubs — or that ship from a low-density spoke — are more likely to experience transit time variability. Zone mapping and hub location analysis inform carrier selection and distribution center siting decisions.
