Verify that you are typing the access code correctly by checking it against your book, and carefully re-type it into the access code field, making sure not to enter any extra spaces.
Please note that access codes are specific to the books with which they are included, and each book has its own access code entry page. Entering a code from a different book will not work, so make sure that you are entering your access code on the correct book's access code entry page. For example, if you have an access code from the book Strengths Based Leadership, verify that you are entering your access code on the Strengths Based Leadership access code entry page.
If the problem persists, please contact us.
NOTE: If you have an access code from How Full Is Your Bucket?, you must use it at http://sf1.strengthsfinder.com. For more information, click here.
