If you have your own ISBN you have two options for displaying it on your book:
i. Blurb placement
When you use our book-making tools and select the option to use your own ISBN your book will have a barcode on the bottom center of the back cover. We can't include a price in that barcode.
Want to customize the placement of the barcode or display a price as part of the barcode? If so, you must add your ISBN and barcode as an image to your back cover. (We recommend using a PNG image rather than a JPG for the sharpest results).
If you upload a book with a custom-placed ISBN then do not select the option to use your own ISBN. Otherwise you'll end up with two barcodes in the printed book.
If you're making a Trade book do not place your own barcode image on the cover. Our Trade books require a Blurb-placed ISBN. If you add a custom-placed ISBN to your Trade book cover you'll end up with two barcodes in the printed book.
