How to track Pakistan Post (`...PK`) EMS and Registered Parcels handed off to USPS

Pakistan Post dispatches Express Mail Service (`EE...PK`), International Air Parcels (`CP...PK`), and Registered Packets (`RR...PK`) from Islamabad, Lahore, Sialkot, and Karachi (`PKKHIA`) to `ISC NEW YORK NY (USPS)` for US customs clearance and USPS delivery.

Barcode transition: Pakistan Post to USPS

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

How the Pakistan Post → USPS handoff works

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

1. Acceptance & Karachi / Islamabad IMPC Export
Pakistan Post collects the shipment (from Sialkot, Lahore, Islamabad, or Karachi) and processes export customs at the International Mail Processing Centre (`PKKHIA` Karachi or `PKISBA` Islamabad).
2. Air Transit to ISC New York (`JFK`)
Dispatches fly via Gulf or European air hubs into `ISC NEW YORK NY (USPS)` at JFK Airport and enter `Processed Through USPS Facility` / `Inbound Into Customs`.
3. USPS Domestic Delivery
After clearing US Customs and Border Protection, USPS delivers the parcel nationwide under the same `...PK` barcode.

Chain Pakistan Post → USPS in code or MCP

Resolve both legs synchronously in TypeScript, curl, or your AI support agent via Streamable HTTP MCP.

REST (Synchronous GET)

# 1. Query Pakistan Post middle-mile scans on the 92… barcode:
curl "https://api.lastscanned.com/v1/track/EE849201948PK?carrier=pakistanpost" \
  -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/EE849201948PK" \
  -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 Pakistan Post 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=pakistanpost`, { headers });
  if (mid.ok) pkg = await mid.json();
}
