Migrating your inventory from Amazon to Walmart? Stop getting your pallets rejected at the receiving dock. Master Walmart Fulfillment Services (WFS) strict GTIN requirements and generate compliant labels instantly.
As sellers diversify their revenue streams, thousands are shipping inventory directly from their Amazon 3PLs into Walmart Fulfillment Services (WFS). However, they are making one catastrophic error: leaving the Amazon FNSKU barcode on the product.
Walmart operates on a fundamentally different philosophy than Amazon. While Amazon relies on internal, proprietary barcodes (FNSKUs) to track seller inventory, Walmart strictly enforces global retail standards. Walmart's automated sorters expect a standard GS1 GTIN (UPC or EAN). If they scan an Amazon FNSKU, your inventory will be flagged, delayed, or outright rejected.
A proprietary barcode starting with "X00". Walmart scanners cannot read this format. Result: Inventory Delayed or Rejected.
A 100% scannable UPC / EAN (GTIN) or a designated WFS Item Label, with all competitor barcodes completely covered by opaque thermal paper.
If you are shipping pallets or parcels to a Walmart fulfillment center, your item-level and case-level labeling must adhere to these parameters.
Unlike Amazon, Walmart requires almost all products to have a universal GTIN. Your product packaging must clearly display a 12-digit UPC-A or 13-digit EAN-13 barcode. This barcode must match the GTIN you submitted when creating your Walmart listing.
Walmart warehouses use multi-directional scanners. If a box has a UPC on the front and an Amazon FNSKU or old manufacturer label on the back, the scanner will crash. You must use opaque, matte thermal labels to cover any competing barcodes. Only ONE scannable barcode should be visible per sellable unit.
If your product does not have a UPC printed on the box, or if you need to cover up an Amazon label, you must print a WFS Item Label. This is a specific sticker format that includes your product's GTIN (formatted as a barcode), the product name, and the seller name.
Enter your product details below. Our engine will construct a compliant WFS Item Label layout perfectly sized for a standard 2x1 inch thermal sticker to cover up your old FNSKUs.
