A customer-return box can carry clues about the product, its warehouse handling, and the parcel that delivered it. Start by asking what each label identifies before using it to research a liquidation item.
These are fictional illustrations, not labels to scan. Formats vary by seller and warehouse. Compare every product clue with the item inside the box.
The product
Product identifiers
Use these to research the product name or model. They do not establish the condition of the particular item in your hands.
UPC / EAN / GTIN
Looks like
Usually a retail barcode with digits beneath it. GTIN means Global Trade Item Number: the identifier encoded in the barcode. GTINs can have 8, 12, 13, or 14 digits; UPC-A carries 12 and EAN-13 carries 13.
Product lookup
Useful for product research. Search the number and compare the result with the item. GS1 provides the identification system; the brand owner normally assigns the product's GTIN.
What it cannot tell you
A product code does not tell you whether this unit works, has all its parts, or belongs in this box.
Privacy
Keep the product code separate from nearby shipping information; crop out names and addresses before sharing photos.
Manufacturer model or part number
Looks like
Look for model or part-number text on the item or its packaging. The manufacturer chooses these identifiers; formats vary.
Product lookup
Useful for finding a manufacturer's product information. Search the brand together with the model or part number, then compare specifications and physical details.
What it cannot tell you
A similar-looking number does not establish compatibility. Check the manufacturer's information before describing which products a part fits.
Privacy
Photograph the model or part number without including any customer or shipping details on surrounding labels.
Marketplace identifier: ASIN
Looks like
An Amazon Standard Identification Number is a 10-character identifier using letters and/or numbers, assigned by Amazon. You can find it in a product page's details or URL; use that to check a suspected ASIN on a sticker.
Product lookup
Useful for finding a product in Amazon's catalog. Compare the model, size and other details on the product page with your item.
What it cannot tell you
A catalog reference does not establish your unit's condition or confirm that the sticker belongs to the contents.
Privacy
Use the product reference alone. Do not include customer details from other labels in a search or listing.
Handling and inventory
Warehouse and returns-processing labels
These labels support inventory handling. Some refer to one unit, some to a seller's product inventory, and others to a whole lot. Read the surrounding text before treating a code as a product identifier.
A retailer’s ‘customer return,’ return-center, or RMA sticker may refer to a return case rather than the product. Compare it with supplier paperwork if available; the sticker alone does not prove the return reason, grade, or contents.
LPN: license plate number
Looks like
A barcode sticker, often on a returned item's box. Amazon uses LPNs to identify specific units during fulfillment and returns processing.
Product lookup
The original FBA seller may be able to match an LPN to a return in the FBA Customer Returns report. If you bought the item through liquidation, start product research with a model number or retail barcode.
What it cannot tell you
The sticker alone does not explain why the item was returned or establish its current condition.
Privacy
Keep return records private. Do not share customer information that appears alongside a handling code.
FNSKU-style fulfillment label
Looks like
An Amazon fulfillment label typically combines a barcode, its readable identifier, a product title and a stated condition. An Amazon-barcode FNSKU links a product to a seller's FBA inventory.
Product lookup
The printed product title can help your research. Treat the FNSKU as an inventory reference, then seek a model number, GTIN or confirmed ASIN for product lookup.
What it cannot tell you
It is not a unique serial number for each physical unit. A printed condition describes the label's record; inspect the item before using that description yourself.
Privacy
Exclude any surrounding buyer or order information from photos and listing text.
Lot or pallet manifest sticker
Looks like
Look for a lot or pallet reference, sometimes with a barcode. Suppliers and warehouses use their own layouts; a manifest is an inventory list with item details and quantities.
Product lookup
Useful for finding the associated supplier manifest or keeping your own stock connected to its source. Use product identifiers in the manifest as research clues, then compare them with the contents.
What it cannot tell you
A pallet reference alone does not identify every product inside or confirm that the contents match the list.
Privacy
Keep supplier paperwork private if it includes names, contact details or delivery addresses. Share only the product details you have checked.
Grading or condition sticker
Looks like
Look for a condition word or grade. Liquidation sellers may describe stock with terms such as used or salvage, or letter grades; check the supplier's grading definitions.
Product lookup
Useful for understanding the seller's stated condition, not for identifying the model. Record your own inspection and test results separately.
What it cannot tell you
Do not infer which functions were tested, which accessories are present, or what a grade means without the supplier's definition and your own checks.
Privacy
Keep inspection notes about the product; leave previous buyers' names and other personal details out.
The parcel
Shipping labels
Names and addresses are personal data. Before taking or uploading photos, remove or fully cover shipping labels and any customer-return QR codes, order references, or address stickers. Never post them or copy another person’s details into notes or listings. Keep separate product identifiers readable.
Carrier tracking and address label
Looks like
Usually a parcel label with sender and recipient details plus a tracking barcode. It is created through a carrier's shipping service; layouts and tracking formats vary.
Product lookup
Useful for tracking a shipment through its carrier. It is not a product catalog identifier; use a separate product label to research the contents.
What it cannot tell you
Delivery information does not establish the exact model, condition or completeness of the item now in the parcel.
Privacy
Remove or fully cover names, addresses and tracking details before taking photos. Never copy someone else's address into your inventory notes or listing.
Next steps
Use the label as a clue
Follow the photograph and identify steps in the pallet unload checklist: exclude personal information, record useful product details, and compare the item with candidate matches.
In the app, Scan displays ‘Barcode found (may be the box's)’ when it detects a barcode. Check whether that barcode belongs to the item inside the box. Any identification is an estimate for you to review.
