Track ePost Global domestic sortation and international postal handoffs before and after USPS or local postal induction.

ePost Global (formerly R.R. Donnelley International Mail / IPA) operates US processing hubs in Los Angeles, Chicago, New York/New Jersey, and Miami, consolidating domestic and cross-border e-commerce parcels for USPS, Canada Post, Evri, and international postal authorities. Querying ePost Global directly reveals sortation and linehaul scans while the postal barcode is still in pre-advice.

Barcode transition: ePost Global to USPS / International Post

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

Origin / middle-mile carrier
ePost Global (epostglobal)
ePost Global / S10 / USPS IMpb barcode

How the ePost Global → USPS handoff works

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

1. Origin pickup & ePost Global hub induction
The parcel is inducted at an ePost Global processing facility (LAX, ORD, EWR, MIA) where weight, dimensions, and customs manifest data are verified.
2. Linehaul & customs pre-clearance
ePost Global routes domestic parcels via zone-skipping linehaul to USPS DDUs, or dispatches outbound air receptacles to international postal authorities.
3. Final-mile postal delivery
USPS or the destination national post scans the barcode on arrival and completes residential delivery.
ePost Global query
GET /v1/track/{number}?carrier=epostglobal
USPS final-mile query
GET /v1/track/{number}?carrier=usps
Why override helps
Shared 92... IMpb and S10 barcodes default to USPS first; ?carrier=epostglobal exposes middle-mile hub scans

Chain ePost Global → 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 ePost Global middle-mile scans on the 92… barcode:
curl "https://api.lastscanned.com/v1/track/92612903029511573030094531?carrier=epostglobal" \
  -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/92612903029511573030094531" \
  -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 ePost Global 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=epostglobal`, { headers });
  if (mid.ok) pkg = await mid.json();
}

ePost Global to USPS & International Mail Consolidator Handoff Tracking FAQ

Why does USPS say Shipping Label Created while ePost Global has my package?
USPS only records an acceptance scan once ePost Global drops the consolidated pallet at your local USPS destination facility. Querying ?carrier=epostglobal shows the live sortation and linehaul events.
How do I track an ePost Global international shipment?
Paste your ePost Global tracking number above or call GET /v1/track/{number}?carrier=epostglobal to view origin processing, flight departure, and final-mile postal handoff scans.
