“Affected devices include Kindle 1st and 2nd Generation, Kindle DX and DX Graphite, Kindle Keyboard, Kindle 4, Kindle Touch, Kindle 5, and Kindle Paperwhite 1st Generation,” reads the message from the Kindle team. Older 2011 and 2012-era Kindle Fire tablets will also lose access to the Kindle Store.

Amazon’s Kindle generational branding is occasionally confusing—that “Kindle Paperwhite 1st Generation” is also referred to as “Kindle Paperwhite (5th Generation)” on Amazon’s support pages because it’s part of the fifth generation of Kindle releases overall. But if you check your Kindle’s software version and see anything older than 5.12.2.2, it means your Kindle is losing access to Amazon’s store and your e-book library.

It’s been a while since any of these devices received active software support from Amazon; only 2024-and-later devices have received the latest 5.19.3.0.1 software update, though 2021 and 2022’s Kindles have been updated as recently as February. Historically, though, Amazon has been willing to allow older, un-updated Kindles to continue to buy and download more books, even if they’re no longer benefitting from new features.
