The Norton product key is the most crucial part of the Norton installation and activation process. You can't validate your purchase, activate your Norton membership plan, or start the Norton.com/setup procedure without a valid Norton product key.
Every Norton purchase comes with a 25-character secret code called a Norton key. The manner of purchasing will determine how you receive the key. You will receive an email with the product key if you purchase the product online, and you will receive a retail card in the Norton antivirus packaging with a secret code written on the back if you purchase the product offline.
Keep the code secure once you've retrieved it since you may be required to produce it at any point throughout the subscription period.
