Give Your Book a Global Identity
Instant ISBN assignment with a free barcode — recognized by every major retailer worldwide. Simple, one-time fee, and available in your local currency.
Retailers won't list a book without one
Your ISBN is your book's passport — it identifies your title across every store, library and distributor on the planet.
Instant assignment
No waiting days or weeks. Your ISBN is assigned the moment you order, so you can keep publishing.
Free barcode included
Every ISBN order includes a print-ready scannable barcode — a separate barcode service costs more elsewhere.
Works everywhere
Amazon, IngramSpark, Google Books, retailers and libraries all recognize Noogul-assigned ISBNs. Each format gets its own.

ISBN questions, answered
Can I use my own existing ISBN?
Yes — if your book already has a valid ISBN you can bring it with you; the Noogul dashboard lets you record and manage it.
Is the barcode really free?
Yes. Every ISBN order from Noogul includes a free print-ready barcode (EAN-13), which most services charge extra for.
Do I need a separate ISBN per format?
Yes — paperback, hardcover and ebook each get their own ISBN so retailers can track them as separate editions. You can order multiple at once.
