Item barcodes and label guidelines

All items must have barcode labels on the outermost part of the sellable unit. The label helps us identify the item, so we’re storing and shipping the right item to customers.

• Place a readable and scannable label with GTIN (14 digits) or UPC (12 digits) on each unit's packaging. You may choose to buy a UPC or GTIN from GS1.
• EAN, vendor SKU number and FNSKU number are not acceptable barcodes or product identifiers.
• Do not put the item barcode on the master case. It should be on the individual, sellable units only.
• Each variant item must have a unique barcode. Variant items without unique barcodes will not be received and may be returned to you at your expense.
• You must cover up old labels and barcodes. 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 item data. We may also charge a fee if the item 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.

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. 

Print receiving labels

At the fulfillment center, we scan the WFS receiving label to verify the shipment and its contents. It is not a carrier label. Your receiving label must include: 

• Return name and address (your information)
• Ship-to address (assigned fulfillment center) 
• Shipment ID (generated by WFS) 
• Shipment ID barcode 
• Box or pallet ID
• GTIN and quantity

Follow these steps to download receiving labels through Seller Center: 

1. Log into Seller Center and go to the Shipping Plans page. 
2. Select View plan.
3. For each shipment, download the master case or pallet receiving labels.
4. Print and stick the labels to your cases or pallets.
