Verify the item and return information first
Before tearing up paperwork, confirm that the product is correct, undamaged, and still within any return window. Save the order record in the retailer account or keep only the document that the return process actually requires.
Once that check is done, remove the complete shipping label. A partially masked phone number or temporary number still does not need to remain on a box headed for a shared recycling area.
Remove the label and barcode together
Carriers and label formats encode different information, so it is not accurate to say that every barcode exposes a full address or phone number. Korea's privacy regulator nevertheless advises removing both the delivery label and barcode.
Peel the label in one piece when possible. If the adhesive will not release, cut out the small labeled section of cardboard and tear the label so its lines cannot be easily reassembled. There is no need for fire or harsh solvents.

Check the inside for packing slips
Packing slips, return forms, and order summaries can include item names, order numbers, or recipient details. Look under padding, keep what is still needed, and tear the rest before disposal.
The same rule applies when reusing a carton for a move or second-hand sale. Removing every old label and barcode protects privacy and reduces the chance of a new shipment being misrouted.
Prompt pickup reduces unnecessary exposure
Bring a delivered box inside when you reasonably can, or use a secure locker or collection point during a long absence. Korean guidance also recommends limiting order information and using a temporary phone number when the service offers one.
A temporary number narrows exposure but is not a guarantee against every risk. Review the retailer's privacy and delivery settings along with how parcels are left in your building.
Verify unexpected delivery texts outside the message
If a text claims that an unknown parcel needs an address correction or small payment, do not use its link. Open the retailer account or carrier's official app independently and check the real order history.
Korean readers can paste a suspicious message into KISA's checker; people elsewhere can use their national reporting service. If you already entered account or card details, contact the relevant service and financial institution promptly.
