Bowker ISBN & Legal Registration Fees
Official Bowker ISBN & Regulatory Formula
Total Expense = Bowker ISBN Package Cost + (Barcodes × $25) + Library CIP Fee + US Copyright Registration ($45)- US Bowker Pricing: 1 ISBN ($125), 10 ISBNs ($295, or $29.50 each), 100 ISBNs ($575, or $5.75 each).

Frequently Asked Questions
Do I need a separate ISBN for my ebook and paperback?
Yes. International ISBN agency standards require every distinct format and edition of a book to have its own unique 13-digit ISBN. Your paperback, hardcover, ebook, and audiobook each need separate numbers.
Why should I buy a 10-pack of ISBNs instead of a single ISBN?
A single Bowker ISBN costs $125. A 10-pack costs $295 ($29.50 each). If you publish just two formats (such as paperback and hardcover), buying two singles costs $250. Buying the 10-pack for $295 gives you 10 permanent ISBNs for future formats and future books at a massive per-unit discount.
Do I need to pay for barcode generation?
No. While Bowker sells barcode downloads for $25 each, legitimate tools like Bookow generate free high-resolution 300 DPI EPS and PNG print-ready barcodes incorporating your ISBN and retail price.
