How to track YunExpress (`YT...`) Italy parcels handed off to Poste Italiane Crono & BRT

YunExpress (`yunexpress`) consolidates cross-border orders in China (`YT` + 16 digits), clears EU customs, and injects Italian e-commerce parcels into Poste Italiane (`5P...` / `3C...` / `UW...IT` Crono/SDA) or BRT Corriere Espresso.

How the YunExpress → Poste Italiane handoff works

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

1. YunExpress China Sortation (`YT...`)
YunExpress weighs and sorts the parcel at origin (`YT` + 16 digits) and pre-allocates a Poste Italiane Crono (`5P...`, `3C...`, or `UW...IT`) or BRT barcode.
2. European Air Freight & Customs Clearance
Cargo flights land at European gateways (Malpensa, Liège, or Amsterdam), clear EU IOSS customs, and truck into Poste Italiane's Milan/Piacenza/Bologna hubs.
3. Poste Italiane / SDA Delivery (`In consegna`)
Poste Italiane or SDA scans the parcel `In transito` → `In consegna` and delivers it across Italy within 1 to 3 working days.
Last-Mile Barcode Extraction
YunExpress exposes the Italian `5P...` / `3C...` / `UW...IT` Poste Italiane barcode in its `LastMileTrackingNumber` field.
Unified Event Timeline
Querying `GET /v1/track/{number}` merges YunExpress air-freight milestones with Poste Italiane last-mile scans.

REST (Synchronous GET)

# 1. Query YunExpress origin waybill (extracts final-mile barcode in .message):
curl "https://api.lastscanned.com/v1/track/YT2611421272084937" \
  -H "Authorization: Bearer lsk_live_YOUR_API_KEY"

# 2. Query the extracted Poste Italiane barcode:
curl "https://api.lastscanned.com/v1/track/5P48291049281" \
  -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: 5P48291049281 (Poste Italiane)")
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();

YunExpress to Poste Italiane & BRT Italy Handoff Tracking FAQ

How do I get the Poste Italiane tracking code from a YunExpress `YT...` number?
Submit your 18-character `YT...` number to `GET /v1/track/{number}`—the API extracts the `5P...`, `3C...`, or `UW...IT` Poste Italiane Crono code and fetches live Italian scans.
Why does Poste Italiane say 'Tracciatura non disponibile' at first?
Poste Italiane activates the tracking code once the physical pallet clears European customs and is scanned at the Milan, Piacenza, or Bologna hub.
How long does YunExpress take to deliver to Italy?
YunExpress Italy Direct Line typically delivers in 7 to 11 calendar days from China.
