all parcels are delivered with authority to leave.
this means the delivery driver will attempt to gain a signature and name if you're home. if you are not home, and there is a safe place to leave the parcel, it will be safely dropped and delivery completed.
if there isn't a safe place, an attempted delivery card will be left and the parcel will be taken to a nearby post office for collection. for better visibility on your delivery, get the free MyPost app.
