KDP adds the barcode to paperback covers from your ISBN metadata. The cover file itself only needs the safe area where it will sit.

FAQ

Frequently asked questions

Do I need to add my own barcode to the cover?

No. KDP places the ISBN barcode automatically from your metadata. Reserve the space instead.

Is the ISBN barcode the same as the ISBN?
