UPS tracking by number, a service provided by the United Parcel Service (UPS), allows users to monitor the progress of their shipments using a unique identifying number assigned to each package.
This service is highly relevant for individuals and businesses that rely on reliable and timely delivery of their shipments. It provides benefits such as real-time updates on the package’s location, estimated delivery times, and proof of delivery. A key historical development was the advent of online tracking in the 1990s, which made it convenient for users to track their packages without having to call or visit a UPS facility.
