On delivery day, park your vehicle within two blocks of the delivery address in a publicly accessible area. You’ll receive a notification in the morning with a 4-hour delivery window, and an “Arriving Now” notification when the delivery driver is headed to your vehicle. When the delivery driver arrives—before your car is unlocked—Amazon verifies that an authorized driver is at the right location with the right package, through an encrypted authentication process. No special codes or keys are given to the driver. The driver will then place the package inside your vehicle and request to relock it. We will let you know when your vehicle is relocked, and you’ll get a final notification confirming the delivery is complete.
