Barcode transition: J&T International to USPS / UniUni / GOFO

Domestic J&T International parcels keep the same 92… / 420… barcode from pickup to mailbox. Pass ?carrier=jtexpress to inspect middle-mile sort scans before USPS induction.

How the J&T International → USPS handoff works

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

1. J&T origin sort & US barcode pre-allocation
J&T International labels the parcel at origin with a USPS 92…, UniUni UUS…, or GOFO GF… barcode.
2. LAX / JFK / ORD Type 86 or formal customs clearance
J&T clears US CBP at the gateway airport and deconsolidates bags at its local container freight station.
3. USPS, UniUni, or GOFO doorstep delivery
The parcel is inducted into USPS, UniUni, or GOFO Express for residential delivery.

REST (Synchronous GET)

# 1. Query J&T International middle-mile scans on the 92… barcode:
curl "https://api.lastscanned.com/v1/track/9261290312833844954982?carrier=jtexpress" \
  -H "Authorization: Bearer lsk_live_YOUR_API_KEY"

# 2. Query USPS final-mile scans on the same barcode:
curl "https://api.lastscanned.com/v1/track/9261290312833844954982" \
  -H "Authorization: Bearer lsk_live_YOUR_API_KEY"

TypeScript (Automatic Handoff Chaining)

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

// If USPS is still waiting on the consolidator parcel, query J&T International middle-mile hubs:
if (pkg.carrier === "usps" && pkg.status === "label_created" && /^(420\d{5})?9[2345]/.test(number)) {
  const mid = await fetch(`https://api.lastscanned.com/v1/track/${encodeURIComponent(number)}?carrier=jtexpress`, { headers });
  if (mid.ok) pkg = await mid.json();
