Last-Mile Parcel Sorting for Couriers and Regional Carriers
Regional carriers and local couriers are taking more parcel volume, and most of it arrives mixed. Sorting it by route before drivers load is where time is won or lost.
More Parcels Are Going to Smaller Carriers
The U.S. shipped 23.1 billion parcels in 2025, and the revenue share held by carriers outside the big four more than doubled, from 3.4% to 7.2% (Pitney Bowes Parcel Shipping Index). Each of those carriers receives mixed freight and has to sort it, often by hand, often by the same drivers who then deliver it.
Peak season adds pressure: national carriers' 2026 residential peak surcharges are one reason shippers look to regional and local carriers. See the Q4 2026 peak season brief.
Who this is for
- Regional carriers and local couriers
- Same-day and next-day delivery services
- Delivery service partners at carrier stations
- New delivery companies without sorting space
Sorted by Route Before Loading
1. Inbound arrives
Linehaul or carrier freight comes in mixed, as it does today.
2. Labels are read
The sorter reads each label and looks up its route, ZIP or driver.
3. Routes are built
Parcels are diverted into chutes, one per route or driver.
4. Drivers load
Drivers pick up a sorted route instead of building it themselves.
