How the ECMS Express → USPS handoff works

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

1. ECMS origin warehouse & KYC/customs pre-clearance
ECMS collects the parcel in Tokyo, Osaka, Los Angeles, or Shanghai under an ECMS… or APE… tracking number.
2. International air linehaul & customs release
ECMS flies the shipment to the destination gateway airport, clears customs, and breaks down the master pallet.
3. USPS, FedEx, or Pitney Bowes final delivery
The domestic partner scans the 926129… (USPS) or FedEx barcode and delivers to the recipient.
