How the TopYou → Colissimo handoff works

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

1. Shenzhen Sorting & Colissimo Pre-Advice
TopYou generates a 13-character `6A...` or `8R...` barcode in China (`Votre colis est prêt à être expédié, il va être remis à La Poste`).
2. CDG / LGG Customs Release
Pallets clear EU IOSS customs at Roissy CDG or Liège and enter a Colissimo Plateforme Colis (PFC Moissy-Cramayel, Gennevilliers, Carvin, or Corbas).
3. La Poste Delivery (`En cours de préparation pour la livraison`)
Your local facteur or Colissimo courier delivers to your boite aux lettres (`Livré`) or Point Retrait.
Colissimo Barcode Format
13 characters starting with `6A`, `8R`, `6G`, or `6M`
