No, a packing slip is not the same as a shipping label. A packing slip is a document used to itemize the products in a package. It is placed on the inside of the package for customer reference. Alternatively, a shipping label is placed on the outside of the package and used by the carrier and shipment company to ensure the product is delivered to the destination. A shipping label includes a scannable barcode and tracking number for tracking the package location throughout the shipping process.
