Quick answer
Modern book barcodes normally encode the ISBN-13 as an EAN-13 symbol, often called Bookland EAN. Remove hyphens for encoding but keep leading digits, validate the ISBN checksum, and follow the printer or distributor's placement and size requirements.
How to do it
- Obtain an officially assigned ISBN and confirm all 13 digits.
- Validate the check digit and generate the EAN-13 bars.
- Export a vector version and test the printed cover proof with a barcode scanner.
ISBN text versus encoded digits
Human-readable ISBNs often contain hyphens that show registration groups and publisher elements. The barcode encodes the 13 digits without punctuation. Optional five-digit add-ons may represent price information, but distributor requirements vary.
Printing on a book cover
Use dark bars on a plain light box, keep left and right quiet zones clear, and avoid placing the symbol too close to trim, folds, or high-gloss artwork. Do not resize the barcode disproportionately in layout software.
Common mistakes to avoid
- Converting an old ISBN-10 by simply adding 978 without recalculating.
- Encoding hyphens into the EAN-13 data.
- Placing artwork inside the quiet zones.
