Barcode & ISBN FAQ for Self-Publishers

Do I need a barcode on my book?

Yes. Every item fulfilled by Acutrack must have a scannable code for inventory and shipping.

What are my options?

You can use one of these:

• ISBN (recommended for most authors)
• UPC (less common for books)
• Free Acutrack DataMatrix code (fulfillment only)

Which option should I choose? (Quick guide)

• Use an ISBN if you:
  • Plan to sell on Amazon, bookstores, or through distributors
  • Want your book treated as a “real” retail title
  • Want wider distribution
• Use a UPC if you:
  • Are selling like a retail product (events, non-book channels)
  • Don’t need bookstore or library distribution
• Use Acutrack’s free DataMatrix if you:
  • Only need fulfillment (e.g., direct-to-consumer, courses, events)
  • Don’t plan to sell through retail or bookstores

Do I need an ISBN for a TikTok Shop?

TikTok Shop requires a product identifier for most categories, and ISBN is one acceptable option alongside GTIN, UPC, and EAN. It's not a book-specific mandate. You can submit any valid identifier your product already has.

Should I use a free ISBN from Amazon KDP?

You can but there are trade-offs:

• Publisher will show as “Independently Published”
• Some bookstores/distributors may not carry it
• You can’t reuse that ISBN elsewhere later

Best practice: Buy your own ISBN if you want full control of your publishing brand.

Where do I get an ISBN or UPC?

• ISBN: Purchase from Bowker (U.S.)
• UPC: Purchase from GS1

Each format/version of your book (paperback, hardcover, etc.) needs its own ISBN.

 👉 Get an ISBN. It gives you the most flexibility and keeps your options open
