Some books sold on Amazon have DRM and some do not. But "DRM" is not listed anyplace on the book descriptions that I have been able to find. How can I know before I buy an ebook from Amazon if it has DRM?

  • This is because Amazon does not want to admit that drm is a problem. – hildred Aug 5 '15 at 2:31

Books that have "Simultaneous Device Usage: Unlimited" listed under "Product Details" do not have DRM (Digital rights management). Those without this disclaimer have DRM.


Usually we can check a Kindle eBook has DRM or not via its product details. We can tell if a book has DRM protection in 3 cases.

  1. If it says "Simultaneous Device Usage: Unlimited", obviously, the book is DRM free.

  2. If it says nothing, it indicates the book is DRM protected.

  3. If it has a "Simultaneous Device Usage", but it gives a number of licenses, such as "Up to 5 simultaneous devices", then it will have DRM.
