The majority of retailers throughout the world will accept UPC or EAN Barcodes from Nationwide Barcode.
The exceptions are some of the major retailers like JP Penney’s, Krogers and Walmart. These retailers require that you provide certificates directly from GS1.
We have heard that Walgreen’s and Macy’s also asks for the barcode certificate but may optionally input the UPC number of each product.
It is your responsibility to ask your retailers if they will accept UPC or an EAN numbers from a company that subdivides barcodes.
