A shipping label is a document attached to a package that provides essential information for its delivery. It typically includes the sender's and recipient's addresses, a tracking number, and details about the contents. Shipping labels help postal services and delivery companies like UPS or FedEx efficiently route and deliver packages. These labels can be printed at home or obtained from shipping centers. They often include barcodes that can be scanned to track the package's journey. Properly affixing a shipping label ensures that the package reaches its destination without delays or confusion.
