Free ISBN Barcode Generator — Create a Book Barcode in Seconds

Kidillus provides the fastest free way to convert your ISBN into a scannable barcode image. Whether you are self-publishing through Amazon KDP, IngramSpark, or Barnes & Noble Press, our generator produces files that meet every major distributor's specification. No account. No watermark. No cost.

How to Create a Barcode from Your ISBN (4 Steps)

1. Enter your ISBN-13 — Type or paste your 13-digit ISBN (starting with 978 or 979) into the first field. Hyphens are allowed; the tool strips them automatically.
2. Add a price code (optional) — If you want to embed a retail price, enter the 5-digit EAN-5 code. Leave blank for a standard KDP barcode. Use 90000 if you want to show "no fixed price."
3. Click Generate Barcode — The barcode renders instantly in your browser. No server upload needed.
4. Download — Choose PDF for print-ready files (recommended for cover designers), SVG for vector editing in Affinity or Illustrator, or PNG for web mockups.

Amazon KDP ISBN Barcode Size & Specifications

Amazon KDP requires the barcode on the back cover of all printed books. The generated file meets these official requirements:

Format	Width	Height	Standard	Status
ISBN-13 only	2.0″ (50.8 mm)	1.25″ (31.75 mm)	EAN-13	✅ KDP & IS compliant
ISBN-13 + Price	2.44″ (62 mm)	1.25″ (31.75 mm)	EAN-13 + EAN-5	✅ KDP & IS compliant
KDP minimum	1.75″ (44.5 mm)	1.0″ (25.4 mm)	EAN-13	Reference only

Our tool outputs above the KDP minimum and at the recommended "nominal" size, so your barcode scans correctly at any retail point-of-sale.

978 vs. 979 ISBN Prefix — Does It Matter?

Both 978 and 979 prefixes are fully valid EAN-13 barcodes. Amazon KDP now issues ISBNs starting with 979-8 at no charge. If you purchased your own ISBN from Bowker (USA), Nielsen (UK), or another agency, it likely starts with 978. Either way, simply enter the full 13-digit number and our generator handles it correctly.

Price Code Guide — Which EAN-5 Code Should You Use?

The optional 5-digit price addon (EAN-5) tells retailers and scanners what your book costs. Here are the most common options:

EAN-5 Code	Meaning	When to Use
90000	No fixed price	Recommended for KDP — price can change freely
5XXXX	USD price	e.g. 51499 = $14.99 · 50999 = $9.99
6XXXX	CAD price	e.g. 61999 = CAD $19.99
(blank)	EAN-13 only	Standard KDP barcode — most flexible option

Do I Need a Barcode for Hardcover Books?

Yes — both KDP paperbacks and hardcovers require the barcode on the back cover. The size specification is identical for both formats. eBooks (Kindle / EPUB) do not require a barcode; the ASIN serves as the digital identifier.

Which Download Format Should I Use?

• PDF — Best for sending to your cover designer or uploading directly to KDP. The barcode is embedded as a raster image at full print resolution.
• SVG — Perfect if you are designing the cover yourself in Adobe Illustrator, Affinity Publisher, or Canva Pro. Infinitely scalable with no quality loss.
• PNG — Ideal for cover mockups, social media previews, or Canva at standard screen resolutions.

Frequently Asked Questions

Is this ISBN barcode generator really free?

Yes — completely free. No account, email, or payment is required. Kidillus provides this as a free resource for the self-publishing community.

How do I convert my ISBN-13 to a barcode?

Enter your 13-digit ISBN into the box above (with or without hyphens), click Generate Barcode, and download your file. The process takes under 10 seconds.

What is the correct barcode size for Amazon KDP?

Amazon KDP accepts EAN-13 barcodes at a minimum of 1.75″ × 1.0″. Our tool generates the recommended size of 2.0″ × 1.25″ (without price) or 2.44″ × 1.25″ (with EAN-5 price code), both of which exceed the minimum and scan reliably.

Can I use this barcode on IngramSpark?

Yes. IngramSpark, Barnes & Noble Press, and most other distributors use the same EAN-13 standard. The generated barcode works across all major print-on-demand platforms.

Does the barcode generator work for 979-8 ISBNs (KDP free ISBNs)?

Yes. Amazon KDP's free ISBNs start with 979-8. Enter the full 13-digit number and the generator produces a valid EAN-13 barcode regardless of prefix.

Do eBooks (Kindle) need a barcode?

No. Kindle and EPUB eBooks are identified by their ASIN, not a scannable barcode. Barcodes are only required on physical printed books.

Which file format is best for printing?

Use the PDF for sending to your printer or uploading to KDP. Use SVG if you are placing the barcode in a design application. Both are vector-based and will remain sharp at any size.

Disclaimer: Kidillus provides this tool free as a resource for authors. While our barcodes meet EAN-13/EAN-5 industry standards and Amazon KDP size requirements, the publisher is solely responsible for verifying ISBN validity and pricing data before bulk printing. Always scan-test a proof copy.
