My ISBN code doesn't work
If your ISBN doesn't work, it could be because:
the code was entered incorrectly. You must write only the numbers of the ISBN, with no spaces or dashes.
No need to enter exercises textbook ISBN code. By entering the student textbook ISBN code, you have already activated all available resources for both on your profile.
The access to the free digital resources of your book (audio, videos, transcriptions, etc.) activated with the ISBN code of the printed textbook will last for 31 days.
However, as long as the textbook is still available for sale and therefore still available on the platform, you can reactivate the access to the content as many times as needed by entering the ISBN code again.
the printed book you have is a hybrid edition. To access its digital resources you don't have to introduce the ISBN, but the 20-character code that is printed on the internal part of the book's cover.
You need to scratch the silver-grey field shown in the screenshot below to see the code.
If after checking all the previous cases your code is still not working, please contact our customer service team by filling in this form. Please indicate the ISBN code you are trying to activate and the book it corresponds to.
