LTL Freight & Heavy Parcel Tracking API (Estes, Saia, XPO, R+L, ABF, TForce, Central Transport, FedEx Freight & More)

Wholesale distributors, industrial suppliers, commercial furniture brands, and B2B ERP/TMS teams rarely ship on parcel networks alone. Once a shipment exceeds UPS or FedEx's 150 lb / 108" length / 165" length+girth parcel limits (where UPS levies a $1,875 Over Maximum Limits penalty—see our 2026 Carrier Surcharges & Rate Guide), orders move on Less-Than-Truckload (LTL) and global freight networks.

Traditionally, tracking LTL PRO numbers across regional and national freight lines meant either logging into 15 separate carrier web portals or paying five-figure annual enterprise contracts for legacy TMS visibility platforms (project44, FourKites).

lastscanned unifies 18+ LTL, pallet, and freight carriers alongside 520+ parcel and postal carriers in a single normalized JSON schema—accessible via synchronous GET /v1/track/:proNumber, batch GET /v1/track?numbers=..., the no-code Web UI Dashboard (app.lastscanned.com/watches), push Webhooks (POST /v1/watches), and our Remote MCP Server (https://mcp.lastscanned.com).

Every PRO number and freight bill below comes from real recorded carrier fixtures supported by GET https://api.lastscanned.com/v1/track/{trackingNumber}:

1. Important Best Practice for LTL PRO Numbers: Always Pass ?carrier=Copy Anchor Link

Unlike parcel carriers that embed check digits and prefixes (1Z… for UPS, 92… for USPS), many LTL freight lines issue plain 8-, 9-, 10-, or 11-digit numeric PRO numbers that overlap across carriers (and with 10-digit DHL Express or 12-digit FedEx numbers).

When querying a numeric LTL PRO number, pass the explicit ?carrier=<slug> parameter so lastscanned routes directly to that freight line without ambiguity:

# Central Transport 9-digit PRO lookup
curl -s "https://api.lastscanned.com/v1/track/301628376?carrier=centraltransport" \
  -H "Authorization: Bearer $LASTSCANNED_KEY"

# Saia 11-digit PRO lookup
curl -s "https://api.lastscanned.com/v1/track/77136436530?carrier=saia" \
  -H "Authorization: Bearer $LASTSCANNED_KEY"

# XPO LTL 9-digit PRO lookup
curl -s "https://api.lastscanned.com/v1/track/817817302?carrier=xpoltl" \
  -H "Authorization: Bearer $LASTSCANNED_KEY"

# Estes 10-digit PRO lookup
curl -s "https://api.lastscanned.com/v1/track/0550000000?carrier=estes" \
  -H "Authorization: Bearer $LASTSCANNED_KEY"

2. Monitoring Open Pallet & LTL Shipments in the Web UI Dashboard (app.lastscanned.com/watches)Copy Anchor Link

Logistics coordinators and receiving docks don't need to write code to track inbound and outbound freight bills across multiple LTL carriers:

1. Open Watches (app.lastscanned.com/watches) in the Web UI Dashboard.
2. Paste up to 100 PRO numbers, select the LTL carrier (Central Transport, TForce Freight, Estes, Saia, XPO LTL, ABF Freight, R+L Carriers, FedEx Freight, Southeastern Freight Lines, etc.), and add a custom label (such as "PO #4821 — Chicago Dock").
3. Each PRO number is looked up immediately and checked automatically on a schedule (every 15 min when out_for_delivery, every 30 min on exception, every 1 hr in transit).
4. Configure Webhooks (app.lastscanned.com/webhooks) (or POST /v1/watches via API) to push signed status updates into your ERP, NetSuite, Acumatica, or Slack channel whenever a pallet arrives at a destination terminal, requires a delivery appointment, or is signed for at the dock.
