How to track SunYou (`SY...`) Germany parcels handed off to DHL Paket & Deutsche Post Warenpost

SunYou Post (`sypost`) consolidates Chinese e-commerce orders (`SY...` / `SYDE...` / `LP...`), flies them into Europe, and injects German parcels into DHL Paket (`00340434...`) or Deutsche Post Warenpost (`35...` / `A0...`) for last-mile delivery.

How the SunYou → DHL Paket DE handoff works

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

1. SunYou Origin Sortation (Shenzhen / Dongguan)
SunYou collects the parcel (`SY...` / `SYDE...`) and prints a dual-barcode label containing a German DHL Paket (`0034...`) or Deutsche Post Warenpost (`35...`) tracking code.
2. Air Transit & EU IOSS Customs Release
Shipments fly into Liège (LGG), Frankfurt (FRA), or Amsterdam (AMS), clear customs under EU IOSS, and are trucked to a German DHL Paketzentrum or Briefzentrum.
3. DHL Paket or Briefzusteller Delivery
DHL Paket delivers larger boxes to your door or Packstation, while lightweight Warenpost mailers are delivered directly into your Briefkasten by your Deutsche Post Briefträger.
SYDE Special Line vs Economy Mail
Registered `SYDE...` and SunYou Special Line shipments include a full end-to-end DHL Paket (`0034...`) or Warenpost barcode, whereas unregistered economy packets (`SYUA...` / `SYBA...`) track up to German hub arrival.
Single-Call Resolution
`GET /v1/track/{number}` tracks SunYou export milestones and links the German DHL/Warenpost final-mile scan chain.
