Decide how the barcode will be supplied before approving the back cover. Follow current KDP cover guidance for the chosen workflow, reserve the appropriate space, and inspect the final barcode placement together with the text and artwork in the exported cover.
Decide which barcode workflow the cover uses
A cover project needs to distinguish between artwork that includes a supplied barcode and artwork prepared for the platform's barcode placement. KDP's current paperback guidance describes both options. Confirm which approach applies before a designer fills the back cover with text and illustration that may later compete with the barcode.
Record the decision with the edition's cover specifications. Do not infer it from an old mockup, especially if the book has several formats or previous editions. A placeholder rectangle can help the design team discuss placement, but it should be clearly identified as a working guide rather than mistaken for the final publication element.
Use current guidance for the actual cover
Consult the relevant KDP barcode and cover instructions for the intended workflow, including the required placement and preparation details. Use the current template and actual edition specifications. A barcode area copied from another book may not establish the correct treatment for this cover or the chosen method of supplying it.
Keep the instruction reference and the template version with the design file. If the trim size, page count, or format changes, review the cover setup again before assuming the reserved space still works. The barcode decision is part of the physical publication package, not an isolated decoration added after the rest of the cover is approved.
Design the surrounding content around the reserved area
Place back-cover copy, credits, and important artwork so they remain understandable with the barcode treatment in place. Inspect the full cover and a back-only view. A figure, symbol, or sentence that appears balanced in the unmarked design may become awkward when a rectangular barcode interrupts it.
Avoid relying on the barcode to hide an unwanted part of the illustration. That makes the composition dependent on a placement assumption and can create problems if the workflow changes. Prepare artwork that remains intentional around the reserved area, with the meaningful elements safely positioned according to the current specifications.
Verify supplied artwork as a separate asset
If the workflow includes a supplied barcode, keep its source and associated identifier record with the project. Check that it belongs to the intended edition and has not been taken from an older cover. A visually similar code or familiar printed number is not enough to establish that the asset represents the correct publication.
Use an appropriate verification method and follow the current production requirements. Do not assume that resizing, recoloring, or adding decorative effects leaves the asset suitable. If the team cannot establish what the supplied barcode represents or whether its preparation is acceptable, resolve that uncertainty before approving the cover rather than treating it as a minor finishing detail.
Inspect the combined export and preview
Review the actual exported cover with the chosen barcode treatment, then inspect the relevant platform preview for the file being submitted. Confirm that no text, credit, or essential part of the artwork is obscured. Check that a working placeholder has not survived alongside the final element or created a duplicate-looking area.
Compare the result with the approved design and current publication record. A correct source asset can still be placed incorrectly in the final file, while a clean-looking design may contain the wrong edition's information. The check needs to cover both the visual relationship and the identity of the publication element used.
Recheck placement after late cover revisions
A new paragraph of back-cover copy or a changed illustration can intrude into space previously reserved for the barcode. Include that area in every relevant late review. Do not rely on an earlier approval when the surrounding content has moved, even if the barcode asset itself is unchanged.
Save the final cover and its review record together. Identify the exact export and the workflow used so future revisions begin with a clear decision. The cover is ready for this part of review when the barcode treatment follows the current requirements and coexists with a complete, readable back-cover design.
Frequently asked questions
Clear answers for this publishing decision.
Do I always need to supply my own barcode image?
KDP’s current paperback guidance describes covers with a supplied barcode and placement when one is not supplied. Confirm the appropriate workflow and current instructions for your publication.
Can a designer finish the back cover before deciding barcode placement?
A draft can explore the composition, but final approval needs the barcode treatment considered. Otherwise, later placement can obscure text or meaningful artwork.
What should be checked after back-cover copy changes?
Inspect the reserved area and the actual final placement again. New text or shifted artwork can conflict with a barcode even when an earlier cover version passed review.
How wide does the full-wrap cover need to be, and how thick is the spine?
The cover width is back cover plus spine plus front cover plus bleed on both sides; the spine width is the final even page count multiplied by the paper-specific factor Amazon publishes, so the cover cannot be sized before the interior page count is final.
