No. The bar code bars represent only the number below. There is no other information contained within the bar code. All information is supplied to you to the wholesaler or retailer.
A barcode is a graphical representation of the numbers below the graphic. UPC and EAN barcodes rely on data being entered into the retailers database. The 12 digit UPC or 13 digit EAN number is associated with the product name, specifications and selling price. When a barcode is scanned, a query is sent to the database and the response is the information about the product.
