Retailers often verify the authenticity of your barcodes by checking in the GS1 Database before they allow you to sell on their site. If your company is not listed in the database as the brand owner of that barcode, your account might be suspended, or you might need to relabel your products. Both will cost you time and money!
Uniquely identify your brand and your barcodes with a GS1 Company Prefix or a GS1 US GTIN and invest in the future of your business. A GS1 Company Prefix will allow you to license a block of barcodes at one time, whereas GS1 US GTIN is a single barcode.
