Item barcodes and label guidelines

All items must have manufacturer barcodes on the outermost part of sellable unit.

• Place a readable and scannable UPC (12 digits) or GTIN (14 digits) label on every individual product packaging sent to the fulfillment center. You may choose to buy a UPC or GTIN from GS1.
• Do not put the barcode on the outer case. It should be on the individual, sellable units only.
• EAN, vendor SKU number, FNSKU number are not acceptable barcodes or product identifiers.
• Variant items must each contain a unique barcode. Variant items without unique barcodes will not be received and will be returned to you at your expense.
• Do not put the barcode on the outer case. It should be on the individual, sellable units only.
• If you print and apply your own barcodes, you must cover the barcode being replaced. Old manufacturer barcodes may cause confusion at the fulfillment center and lead to delays.  
• You may include additional product details on a label as long as the correct barcode is included.
• All labels must be visible and scannable. The fulfillment center may refuse and return at your expense any unit that doesn’t have a scannable label with product data. We may also charge a fee if the product doesn’t contain a scannable barcode.
• Any damaged labels or barcodes will cause a delay in receiving time. 

Example of correct product label

Do not use seller SKU or FNSKU label

All items must be clearly and permanently marked with the country of origin. The label must be located where it can be seen while casually handling the item. Where the label goes depends on the item:  

• For clothing, a label stating “Made in . . .” qualifies.

• For shoes, the country-of-origin label must physically be on both shoes in the pair. The country of origin needs to be on more than just the website or shoebox.

• For some items, the country-of-origin label may go on the outer packaging. 

Generate and print item label 

You can print an item label for each item in your shipment or create your own labels with your own tool. Choose the method that works best for you and follow the steps below.

Print label for each item 

1. Log into Seller Center and go to Inventory. 

2. For each item, select the 3 dots.

3. Print and stick one label per item. 

Printing tips 

All barcodes must be scannable by Walmart equipment. To maintain print quality: 

• Use a printer with a resolution of 300 DPI or greater.

• Use the correct label stock for your printer. 

• Periodically test your printed barcodes by scanning them. 

• Test, clean, and replace your printer heads as needed. 

Generate and print receiving label 

At the fulfillment center, we use the WFS receiving label to verify the arrival and contents of the box or pallet. It is not a carrier label. Your receiving label must include: 

• Return to (ship from) seller name and seller address 

• Pallet and box counts 

• Shipment ID (generated by WFS) 

• Ship-to address (assigned fulfillment center) 

• Shipment ID barcode 

• Label type: mixed SKUs case, single SKU case or pallet 

Follow the steps below to create a label through Seller Center. 

1. Log into Seller Center and go to Shipments. 

2. Find your shipment and select the 3 dots, then choose Print labels.  

3. For each shipment, select Print labels. The label will download to your device.

4. Print and stick the labels to your boxes or pallets.

Battery labeling 

Cases must be marked to meet DOT regulations. Cases that are shipped to fulfillment centers that do not comply with DOT regulations must be re-labeled, at your expense, before shipping to customers. Markings cannot be obstructed or covered by any other labeling. Labels cannot be folded over the edge of the shipping case.
In addition, here are weight and piece restrictions per master case for batteries:
