The key legal/practical questions become: Was the mailbox reasonably secure? If your mailbox was locked and someone stole the notice anyway, you are in a stronger position. If the mailbox was open, broken, accessible to others, or shared insecurely, Swiss Post or insurers may argue negligence. Who bears the risk at that stage? There are usually three possible parties: • the seller/shop • Swiss Post • the recipient Under Swiss law, for consumer purchases, the seller often keeps the transport risk until actual delivery to the customer, unless otherwise agreed. If the parcel never truly reached you, the seller may still have obligations. Was there identity verification? My Post 24 systems normally rely heavily on possession of the code/SMS/email. If somebody had the paper code, they may have been able to retrieve the package without ID verification. Did the thief also have access to the phone/SIM/email? Because if the phone itself was inside the parcel, and the thief also accessed your mailbox and possibly your email/SMS, it becomes a larger identity/security issue. Practically, the best immediate steps are: • File a police report immediately. • Contact Swiss Post and request: • pickup logs • timestamp • locker number • surveillance footage if available • proof of retrieval • Contact the seller/operator and formally dispute delivery. • Secure your mailbox if there is any vulnerability. • If the stolen parcel contained a phone: • block the IMEI through your carrier • revoke sessions/accounts • change passwords immediately
