|The sender typically determines whether a signature is required for packages. In some instances UPS drivers may require a signature for deliveries on their route. You can authorize UPS to leave packages without signing by enrolling in UPS My Choice®.
Please note that the Authorize Shipment Release feature may not be available if UPS delivers to an area that requires a signature for every package delivered, or a Delivery Confirmation Signature Required is requested by the sender.
After you sign up, your notification preferences will only apply to future shipments. It can take up to five minutes before you can begin using UPS My Choice. If your packages require a signature, you must authorize each package individually by tracking it and selecting Provide Delivery Instructions.
