  • Yes, we are the ONLY barcode seller 

    whose barcodes work on Amazon!

  • Each different product you sell requires its own barcode. For example, if you sell a t-shirt that comes in one color and 3 different sizes you would need to buy 3 barcodes. If the t-shirt comes in 2 sizes and 3 colors you would need 6 barcodes. This way, if one of the colors/sizes is selling faster than the others, the store can simply look in their computer and see which one needs to be replenished without having to do a manual shelf count. This same formula applies for all styles, colors, flavors, sizes or any other variation of your product. They all need their own unique barcode.

  • There is no information actually stored or encrypted in a barcode. When you go to sell your product at a store, that store will have you fill out a product information form.

The store then manually enters that information into their inventory management computer. This way, when they scan your barcode at the register, it calls up that form in their system. In other words, the barcode is simply a link between your product and the product information form you fill out for each store that sells your product.
