If you have a number of books from Kindle you probably already know that you are blocked from reading them in any reader application other than Kindle. The Kindle system encrypts files so they can only be read by a specified Kindle reader. The encryption method uses your Kindle’s serial number and a personal ID that was assigned to you as a Kindle buyer. However, you are not allowed to know your PID. Fortunately there is a way to find your PID for Kindle and the iPhone app.

Go to the home page on your Kindle device and select the settings page. Type in “411.” You will be shown a page that includes your Kindle’s serial number.
Open your favourite browser on your home computer and go to the Preston Lee Kindle Tools page (see Resources). Enter your email address and the serial number without the spaces and press the “Calculate” button. This will generate your PID.
