Spring GDS (PostNL Group) (spring)→USPS (usps)

Track Spring GDS European cross-border e-commerce parcels through US ISC customs and USPS delivery.

Spring GDS (Global Delivery Solutions, part of PostNL Group) consolidates cross-border e-commerce shipments from the UK and Europe using S10 postal barcodes (LS…NL, LX…NL, RU…GB) and commercial tracking numbers that hand off to USPS upon arrival at JFK, ORD, or LAX.

How the Spring GDS → USPS handoff works

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

1. Spring GDS European hub sortation
Spring GDS collects the parcel in the UK, Netherlands, Germany, or Spain and processes it at its international sorting center.
2. Transatlantic flight & US ISC customs
The parcel flies to New York (JFK), Chicago (ORD), or Los Angeles (LAX), where CBP and USPS ISC scan the S10 barcode.
3. USPS domestic delivery
USPS routes the parcel through its regional network and completes final delivery.

# 1. Query Spring GDS (PostNL Group) middle-mile scans on the 92… barcode:
curl "https://api.lastscanned.com/v1/track/LS123456789NL?carrier=spring" \
  -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/LS123456789NL" \
  -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 Spring GDS (PostNL Group) 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=spring`, { headers });

Spring GDS (PostNL Cross-Border) to USPS International Mail Handoff Tracking FAQ

Who delivers Spring GDS packages in the United States?
Spring GDS partners with USPS (and regional commercial injection partners) to deliver European cross-border e-commerce parcels across the United States.
Why does my UK or German order have an NL tracking number?
Because Spring GDS is a wholly owned subsidiary of PostNL, many European cross-border parcels route through PostNL's international exchange hub in the Netherlands and carry an LS…NL or LX…NL barcode.
