Cainiao Italy Linehaul to Poste Italiane Crono & SDA Express Handoff FAQ

Why does my AliExpress tracking number start with 5P or 3C in Italy?
`5P...` and `3C...` are Poste Italiane Crono Economy / Standard barcodes pre-allocated by Cainiao in China so the parcel injects directly into Poste Italiane / SDA sorting in Milan or Bologna.
How long does Poste Italiane take after Cainiao clears Italian customs?
Once scanned at the Milan or Bologna hub (`In lavorazione presso il Centro Operativo Postale`), delivery typically takes 2 to 4 business days (3–5 days for Sicily and Sardinia).
Why does poste.it say 'La spedizione è stata creata dal mittente' for 5 days?
Cainiao transmits the electronic manifest to Poste Italiane when the parcel departs China; Poste Italiane only records physical scans after the truck arrives in Italy.
