Simply tape the shipping service label that's included in your welcome pack to the outside of your box so that the entire label is visible.
Please do not place the label over any seams or closures on the package; ensure there are no other shipping or tracking labels attached to your box, and that you do not cover the barcode.
Remember each shipping label's barcode is unique to each of the boxes you're sending - please do not use the same label for multiple boxes.
