To track and trace a package, use the forms in the top of this page. UPS Tracking offers several ways to track, and provides convenient ways to stay informed of current status, unexpected delays, and ultimately the delivery of your shipment. If you don't find your shipping courier, please contact us so that we add it to the service. It contains most of the global couriers as well as local shipping providers and post/EMS companies. Track a PKG offers a quick way to track trace your package. There are other ways to track items, including by Delivery Order, Sub-PRO Number and a UPS Service Notice. Tracking numbers stay with their parcel throughout their journey, and they make it possible for senders and receivers to check exactly where an item is. This was important because mail delivery often included multiple couriers in varying environmental circumstances, which made it possible for a mail to get lost. Every time an item is shipped with UPS, a tracking number is automatically generated. Package tracking developed historically because it provided customers information about the route of a package and the anticipated date and time of delivery. Package tracking (or package logging) is the process of localizing shipping containers, mail and parcel post at different points of time during sorting, warehousing, and package delivery to verify their provenance and to predict and aid delivery. If you were notified by a shipper that they have sent out a package and believe it has been delayed or possibly lost, contact the customer service. If you do not have the tracking number from the label or receipt, please contact the shipper. The tracking number is given to the sender when they make the shipping order with SF Express.
