DHLink (DHgate) (dhlink)→USPS / Yanwen / 4PX (usps)

Track DHgate orders shipped via DHLink across Chinese origin consolidators (Yanwen, 4PX, China Post) and US final-mile USPS delivery.

DHLink is DHgate’s official cross-border logistics platform, aggregating Yanwen, 4PX, YunExpress, and CNE Express under unified DHgate seller shipping labels. Querying DHLink or the underlying S10 / IMpb barcode on lastscanned tracks the shipment from Chinese merchant dispatch through USPS final delivery.

Barcode transition: DHLink (DHgate) to USPS / Yanwen / 4PX

Domestic DHLink (DHgate) parcels keep the same 92… / 420… barcode from pickup to mailbox. Pass ?carrier=dhlink to inspect middle-mile sort scans before USPS induction.

How the DHLink → USPS handoff works

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

1. DHgate seller dispatch & DHLink warehouse scan
The seller hands the parcel to a DHLink pickup station or partner consolidator (Yanwen, 4PX, YunExpress).
2. Export customs & transpacific flight
The shipment clears Chinese export customs and flies to a US International Service Center (ISC New York, Los Angeles, Chicago, or Miami) or commercial airport gateway.
3. USPS final-mile delivery
USPS scans the S10 or 92… IMpb barcode and delivers the package to the buyer’s mailbox.
DHLink query
GET /v1/track/{number}?carrier=dhlink
Yanwen / 4PX query
GET /v1/track/{number}?carrier=yanwen or ?carrier=4px
USPS final-mile query
GET /v1/track/{number}?carrier=usps

REST (Synchronous GET)

# 1. Query DHLink (DHgate) middle-mile scans on the 92… barcode:
curl "https://api.lastscanned.com/v1/track/92612903029511573030094531?carrier=dhlink" \
  -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 DHLink (DHgate) 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=dhlink`, { headers });

DHLink (DHgate Logistics) to USPS, Yanwen & 4PX Seller Shipping Handoff Tracking FAQ

How do I track a DHgate package shipped with DHLink?
Paste your DHgate tracking number into the lookup above or call GET /v1/track/{number}?carrier=dhlink. If your barcode starts with YT…, 4PX…, or 92…, lastscanned can also query YunExpress, 4PX, or USPS directly.
Why is my DHgate USPS tracking number stuck in Pre-Shipment?
When a DHgate seller uses a commercial linehaul consolidator via DHLink, the 92… USPS label is printed in China and only receives its first USPS scan after landing in the US and clearing customs.
