Barcode transition: Winit to Royal Mail

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

How the Winit → Royal Mail handoff works

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

1. Winit Midlands Fulfillment or LHR Linehaul (`WT...`)
Winit packs the order at its Tamworth/Midlands UK fulfillment center (or clears China air cargo at Heathrow) and prints a Royal Mail `...GB` barcode.
2. Royal Mail Midlands Super Hub Induction
Royal Mail trailers collect directly from Winit's Midlands docks and scan `Item received` at the Midlands Super Hub (Daventry).
3. Local Delivery Office & Postman Delivery
Royal Mail delivers within 24–48 hours across the UK (`Ready for delivery`).

REST (Synchronous GET)

# 1. Query Winit middle-mile scans on the 92… barcode:
curl "https://api.lastscanned.com/v1/track/WT84920194834GB?carrier=winit" \
  -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/OJ849201934GB" \
  -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 Winit 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=winit`, { headers });
  if (mid.ok) pkg = await mid.json();

Winit UK Fulfillment (Tamworth/Leicester) & Linehaul to Royal Mail Handoff FAQ

How fast are Winit UK warehouse orders delivered by Royal Mail?
Orders fulfilled from Winit's Tamworth/Midlands UK warehouse are inducted into Royal Mail the same evening and typically arrive in 1 to 3 working days via Royal Mail Tracked 24 or Tracked 48.
Why does Royal Mail say 'Sender despatching item' on my Winit order?
Either the parcel is awaiting the evening Royal Mail trailer pickup at Winit's Tamworth warehouse, or it is a cross-border linehaul shipment still in transit from China to Heathrow.
