Normally, UPS requires the signature of the receiver for all deliveries. As an exception, deliveries in certain countries are allowed on “Driver release” (delivery in a location in the receiver‘s premises without the need for a signature) or on “Letter box release”. Letter box release is a secured release by a service provider which will allow certain residential packages to be left in a safe letter box without a signature.
Use Signature Required to prevent the use of “Driver Release” or “Letter Box Release” in applicable countries.
