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 are crucial for ensuring that packages reach their intended destinations efficiently. These labels can be printed at home or obtained from shipping services like UPS, FedEx, or USPS. They often include barcodes that can be scanned to track the package's journey. Properly affixing a shipping label helps prevent delays and ensures accurate delivery.
