How to track Yanwen (`YT`/`UG`/`UV`) Belgium parcels handed off to bpost via Liège Airport

Yanwen Logistics (`yanwen`) flies cross-border marketplace parcels directly into Liège Airport (LGG) and injects Belgian orders into bpost (`3232...` 24-digit domestic barcode or `LE...BE`) for next-day delivery across Flanders, Wallonia, and Brussels.

Barcode transition: Yanwen Logistics to bpost (Belgium)

When Yanwen Logistics clears customs and hands off to bpost (Belgium), lastscanned surfaces the secondary tracking number in the top-level message field.

How the Yanwen → bpost handoff works

Follow the parcel across both networks without waiting on asynchronous webhooks or losing visibility at the handoff boundary.

1. Yanwen Consolidation & Last-Mile Number Allocation
Yanwen collects the parcel in China (`UG...YP` / `UV...YP`) and generates a 24-digit Belgian bpost (`3232...`) or `LE...BE` tracking barcode (`Exchange the last mile tracking number`).
2. Direct Cargo Flight to Liège (LGG)
Because Liège Airport (LGG) is Belgium's primary China-to-Europe e-commerce cargo hub, Yanwen air pallets land directly in Belgium and clear Belgian customs within 24–48 hours.
3. bpost Sorting (Brussels X / Antwerp X / Charleroi X) & Delivery
bpost inducts the parcel at its national sorting center and delivers it the next working day to your home, bpost Cubee locker, or Point Poste.
`Exchange the last mile tracking number` Extraction
Yanwen's tracking feed emits an explicit `Exchange the last mile tracking number` event containing the 24-digit `3232...` bpost barcode.
Automatic Stitching
`GET /v1/track/{number}` extracts the `3232...` bpost barcode from Yanwen and merges Belgian last-mile delivery scans.

REST (Synchronous GET)

# 1. Query Yanwen Logistics origin waybill (extracts final-mile barcode in .message):
curl "https://api.lastscanned.com/v1/track/UG849201948YP" \
  -H "Authorization: Bearer lsk_live_YOUR_API_KEY"

# 2. Query the extracted bpost (Belgium) barcode:
curl "https://api.lastscanned.com/v1/track/323248291049281920384712" \
  -H "Authorization: Bearer lsk_live_YOUR_API_KEY"

TypeScript (Automatic Handoff Chaining)

const headers = { Authorization: `Bearer ${process.env.LASTSCANNED_API_KEY}` };
const originRes = await fetch(`https://api.lastscanned.com/v1/track/${encodeURIComponent(number)}`, { headers });
const originPkg = await originRes.json();

// Extract secondary barcode from top-level message ("Last mile tracking number: 323248291049281920384712 (bpost)")
const handoff = originPkg.message?.match(/^Handed to (.+?) as ([A-Z0-9-]+)$/i);
if (handoff) {
  const [, , lastMileNumber] = handoff;
  const destRes = await fetch(`https://api.lastscanned.com/v1/track/${encodeURIComponent(lastMileNumber)}`, { headers });
  const destPkg = await destRes.json();

Yanwen Logistics to bpost Belgium Handoff Tracking FAQ

How do I find my bpost tracking number on a Yanwen (`...YP`) parcel?
When Yanwen prepares your parcel for export, it logs a `3232...` (24 digits) or `LE...BE` barcode in the `Exchange the last mile tracking number` event, which `GET /v1/track/{number}` resolves automatically.
Why are Yanwen deliveries to Belgium so fast after landing?
Most Yanwen European cargo flights land directly at Liège Airport (LGG) in Belgium, so there is no cross-border trucking delay before bpost receives the pallet.
Can I divert my Yanwen → bpost parcel to a bpost locker?
Yes—once the `3232...` barcode appears in your My bpost app (matched via your email and Belgian address), you can set your preferred Point d'enlèvement or Distributeur de colis.
