How to track Pos Malaysia (`...MY`) EMS and international parcels handed off to USPS

Pos Malaysia dispatches Pos Laju EMS (`EE...MY` / `ER...MY`), Air Parcels (`CP...MY`), and FlexiPack / ePacket (`LP...MY` / `RR...MY` / `RQ...MY`) from Kuala Lumpur International Airport (`KUL`) to USPS International Service Centers for US delivery.

Barcode transition: Pos Malaysia to USPS

Domestic Pos Malaysia parcels keep the same 92… / 420… barcode from pickup to mailbox. Pass ?carrier=posmalaysia to inspect middle-mile sort scans before USPS induction.

How the Pos Malaysia → USPS handoff works

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

1. Pos Malaysia / Pos Laju Acceptance & KLIA Export
Pos Malaysia processes the parcel at PMIH Kuala Lumpur International Airport (`KUL`) and records `Dispatch to country of destination`.
2. Transit & Arrival at US ISC Gateway
Air dispatches fly via transpacific or Middle East/European hubs into `ISC LOS ANGELES CA (USPS)`, `ISC SAN FRANCISCO (USPS)`, or `ISC NEW YORK NY (USPS)`.
3. USPS Customs Clearance & Final Delivery
After US CBP clearance, USPS sorts and delivers the parcel to your US address using the same `...MY` S10 barcode.
Origin Postal Operator
`posmalaysia` (Pos Malaysia Berhad)
US Final Mile
`usps` (United States Postal Service)
Unified API Resolution
`GET /v1/track/{number}` merges Pos Malaysia KLIA export scans with USPS domestic events.

REST (Synchronous GET)

# 1. Query Pos Malaysia middle-mile scans on the 92… barcode:
curl "https://api.lastscanned.com/v1/track/LP661177776MY?carrier=posmalaysia" \
  -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/LP661177776MY" \
  -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 Pos Malaysia 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=posmalaysia`, { headers });
  if (mid.ok) pkg = await mid.json();
}
