If UPS is unable to complete the delivery of a shipment, a UPS Service Notice will be left at the address stating that a delivery has been attempted.
On the second business day and, if necessary, on the third business day, UPS will attempt to deliver the shipment without additional charge. Each UPS Service Notice should include a handwritten UPS Service Notice number written in by the driver. You can use this number to track, locate, and verify the arrival of shipments. Select the Tracking tab and enter your UPS Service Notice number as you would a tracking number.
