Check whether the box still suits this parcel
Start with the packed item you are sending. A box that arrived safely with a light garment may be a poor fit for a heavier object. Check its size, weight rating where provided, wall strength and remaining space for cushioning. Examine the base, corners, seams and flaps before spending time removing the old label.
Press lightly along the walls to find soft areas and look for crushed corners, punctures, separated layers or water damage. Check that both sets of flaps remain attached and can close normally. If the box has been cut down or opened roughly, inspect those areas carefully. FedEx's packaging guidance asks for durable, undamaged packaging when reusing it. UPS specifies a rigid box with attached flaps and attention to the stated weight limit. FedEx customer packaging guidelines · UPS UK packaging guidance
Turn the box over and find every old shipping code
Check all six faces and any loose flaps. A small return sticker on the base or a second tracking label near a handle can be easy to miss. Look for old recipient addresses, carrier routing stickers, tracking barcodes, return labels and paperwork pouches. Check a pouch's contents before assuming the label underneath is the only old document.
| What you find | What to check before sending |
|---|---|
| Old shipping label or return barcode | Remove it, or cover it fully where the booked carrier permits concealment. |
| A second carrier sticker on another face | Clear its old tracking or routing information too. |
| Clear document pouch | Remove the old documents and clear any old label or code that remains visible. |
| Fragile, orientation or other handling mark | Check whether it still applies to the new contents and service. |
| Battery, dangerous-goods or other regulated marking | Check the new shipment's specific carrier instructions before preparing the box. |
| Manufacturer's box rating or strength information | Use it to help check that the box suits the new packed weight. |
FedEx UK directs senders to remove old labels and barcodes when reusing a box. UPS UK permits old labels and previous shipment markings to be removed or concealed. Use the rules for the carrier on your new booking. FedEx UK parcel labelling · UPS UK packaging guidance
Clear the old information without weakening the box
Try lifting an accessible edge of the old label and peeling it slowly while supporting the cardboard. Stop if large areas of the outer paper pull away. Judge the wall after removal. A rough patch can reduce the surface available for the new label, and deep tears can affect the box itself.
If a stubborn old label remains and the booked service allows concealment, cover the whole old routing area with opaque material that stays fixed to the box. Check the old address, barcode and any separate tracking sticker. Hold the box in good light and inspect from different angles. A cover that lets dark bars show through still needs attention.
Choose the position for the new label after clearing the old marks. If the fresh label will sit on a cover, the adhesive is bonding to that cover. Check that both layers stay flat and that the cover has firm edges. A clean patch of original cardboard is easier to assess than a stack of torn labels and tape. If a satisfactory result is difficult, use another box that meets the service requirements.
Repack the contents and seal the closures
Remove loose old packing material and check whether the cushioning suits the new item. Fit the contents and fill the space needed to limit movement without forcing the box to bulge. Follow your carrier's cushioning guidance for fragile, sharp, heavy or awkward items. Close the flaps to check the final shape before applying fresh tape.
Seal the closures with packaging tape suitable for the booked service. Work on a dry surface and ensure the tape bonds to firm material. Check the bottom as carefully as the top. A box can look tidy around the new label while an old base seam is ready to open. Weigh and measure the parcel after packing, since the finished dimensions and weight determine the booking.
DHL Express UK describes sealing the centre and edge seams using an H pattern. Other carriers publish their own sealing and material guidance. Use the carrier's instructions for the shipment you have booked. DHL Express UK packing guidance
Attach the current label to one firm, flat face
Print or retrieve the current label from the original booking. Match the recipient and tracking reference to the item before peeling or sticking it. Place the full label on one suitable face where the code and address remain flat and visible. Keep it away from a taped seam, flap join, damaged patch or corner that would force a fold.
Check the label's edges after application. A corner placed over a dent can lift when the parcel is handled. Move the position or use suitable packaging if there is too little flat space. Follow the booked carrier's instructions for any documents that must travel outside the box, and keep them clear of the routing label.
Take one final circuit around the parcel. Confirm that the old destination and old shipping codes are gone or fully concealed as permitted, and that the current barcode is complete. Save the new booking and drop-off or collection confirmation with the matching order. FedEx UK parcel labelling
Carrier instructions
Common questions
Can I reuse a cardboard box to send a parcel?
Check your booked service's packaging requirements. The box needs to be sound, suitable for the item's size and weight, and free from old routing labels or misleading markings.
Can I put the new label over the old shipping label?
Remove the old label where possible. If the carrier allows covering, use fully opaque material that hides the whole old address and barcode, with secure edges. Check the rest of the box as well.
Is a black pen enough to hide an old barcode?
Ink can leave parts of the printed code visible. Remove the old routing label, or use a completely opaque cover if the booked service permits concealment.
What if removing a label tears the cardboard?
Inspect whether the damage is only superficial or whether the outer wall is weakened. Use another sound flat patch for the new label. Choose a different box if the old label cannot be cleared safely or the box has lost its strength.
Do I remove the box manufacturer's barcode too?
Focus on old shipping labels, addresses, tracking codes and markings from the previous shipment. Keep the box's strength information available when checking its suitability, and follow any broader marking requirements for your carrier.
