To make changes to your Kindle account, you must first create an account on Amazon.com and register your reading device. You make all necessary edits through this Amazon account, just as you buy books, magazines and newspapers for your Kindle this way.
Create an account on Amazon.com. Register by clicking on the "Your Account" tab on the top right corner of Amazon's home page. Fill out the name, e-mail and password information. In order to download books and other information, you must link your Kindle reading device to an Amazon account.
Click on the "All Departments" box on the left side of the Amazon page next to the search bar. Select the "Kindle Store" and press "Enter" on the keyboard or "Go" next to the search bar. Choose the "Manage Your Kindle" tab, located on the right half of the web page.
Enter the serial number for your Kindle in the field provided on the main page of the "Manage Your Kindle" tab. The serial number is located on the settings page or on the back of the Kindle device. Click on the "Register a New Kindle" button. Once you have clicked on this button, your Kindle will be linked to your account and you will be able to purchase items through your reading device or on a computer.
View the list of Kindle devices registered to your name, and click on the "Edit Info" link next to the device you wish to change on the "Manage Your Kindle" page. Delete the old information and enter in a new name and e-mail address in the appropriate boxes where prompted. Click on the "Update Information" button when finished to save the new information.
The "Manage Your Kindle" area of your account on Amazon.com allows you to register, deregister and change account information for all reading devices produced by Amazon.
