How can I get a Book Code?

How can I tell if my product license is still valid?

If you have activated a Book Code in the past, check to see if the chapters of your online book beyond chapter 3 are viewable. If so, then your product license is still valid. If not, you need to purchase a new Book Code.


Is the product license or Book Code included with my physical book?

What is a Class Code and how do I get one?

A Class Code is a unique code beginning with “CL-” that connects a student profile with a teacher profile. Your teacher must provide you with a Class Code, and we recommend that you create your student user profile with it before purchasing and activating a Book Code.


How do I access my book? BlinkLearning states that I do not have a license.

Each user must purchase and activate a Book Code from Klett USA or an authorized retailer. If you purchased from the Klett USA webstore, you will have received an email with your Book Code. This Book Code must be activated in your “Subjects” area in your Blinklearning profile.

You must have an active Book Code for each product assigned to your course. If you have properly activated a Book Code and are still experiencing troubles, check to see if there are additional books in your course that you need a license for.


I have purchased a Book Code, but I cannot log in.

At the login page, click on “Forgot your password?” to enter your email and reset your password. Check your SPAM messages if you do not see an email shortly. If you still do not receive an email, you may have entered your email/username incorrectly when you created your user profile. To access your account if you spelled your email incorrectly, you must contact with the Book Code that you purchased and an explanation of the problem, and they will send you your username and a reset password.


How long is my Book Code valid?
