SF Express (sfexpress)→Correos (Spain) (correos)

How to track SF Express (`SF...`) Spain parcels handed off to Correos, Correos Express & SEUR

SF Express (`sfexpress`) transports cross-border Chinese e-commerce orders to Spain (`SF...` 15-character waybill) and injects them into Correos (`PQ...` Paq Estándar /Paq Ligero), Correos Express, or SEUR after Madrid customs release.

How the SF Express → Correos handoff works

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

1. Origin Pickup & Pre-Registration (`Pre-registrado`)
SF Express collects the parcel in China (`SF...`) and electronically pre-registers a Spanish Correos `PQ...` label (`Envío pre-registrado en el sistema de Correos`).
2. Air Transit & EU IOSS Customs
The shipment flies into Madrid-Barajas (MAD) or Liège (LGG), clears customs, and is handed over to Correos's CTA Madrid (Coslada) sorting hub.
3. Correos `En reparto` Delivery
Correos scans `Admitido` → `En proceso de entrega (En reparto)` and delivers the parcel to your home or Citypaq locker.
Dual SF + PQ Barcode
The 23-character Correos `PQ...` barcode is printed directly on the hybrid shipping label in China and linked in SF Express's tracking API.
Automatic Handoff Stitching
Passing the `SF...` number to `GET /v1/track/{number}` returns both SF Express air scans and Correos Spain last-mile events.

SF Express to Correos Spain Handoff Tracking FAQ

Why does Correos.es show 'Pre-registrado' on my SF Express package?
`Pre-registrado` means SF Express created the Spanish Correos `PQ...` label in China, and Correos is waiting for the physical parcel to arrive in Madrid after air transit.
How long does SF Express take to deliver to Spain?
End-to-end delivery from China to Peninsular Spain via SF Express and Correos typically takes 7 to 11 business days.
Will I have to pay customs (ADT Postales) on an SF Express → Correos parcel?
No—marketplace and DTC orders under €150 shipped with pre-generated `PQ...` domestic Correos labels clear via EU IOSS with VAT prepaid.
