Clients selling books need to be aware that many books have multiple barcodes printed on them. Some publishers will include ISBN, UPC and EAN barcodes on the book cover. ONLY the UPC barcode should be scanned or meticulously entered by hand into the UPC field of Retail Pro. The UPC field is a special field which includes an algorithmic check digit.
Typically, if a book does include more than one barcode, they will be listed side-by-side. It is important in those cases for retailers to COVER the barcodes other than UPC when scanning items into inventory, or onto a document.
