To activate your subscription, in the Norton product main window, click Activate Now. When you are using a new product key to activate, the remaining days with your current subscription do not get added to the subscription associated with the new key.
To activate Norton antivirus or any Norton product, follow these steps:
Install Norton:
If you haven’t installed Norton yet, download the installation file from Norton’s official website.
Run the installer and follow the on-screen instructions to complete the installation.
Activate Norton:
Open the Norton product you just installed.
If prompted, sign in to your Norton account. If you don’t have an account, create one.
Enter the Product Key:
When the activation screen appears, you’ll need to enter your 25-character product key. You can find this key on your Norton product box or in the email confirmation if you purchased it online.
Automatic Activation (for Online Purchases):
If you purchased Norton online, the software should automatically recognize your account and activate without needing the product key.
Complete the Activation:
After entering the product key (or completing the online process), Norton will activate your subscription and your product will be ready to use!

Find your product key
You can find the product key in one of the following ways:
- Purchased from the Norton™ official site: You can find your product key in the order confirmation email or on your Norton account.
- Purchased a boxed product: The product key is printed either on the box or on the back of the card.
- Got the service from a service provider: Contact your service provider for the activation PIN.
- Came pre-installed on your device: You may find the product key in the text file at Program Files > Norton. If you do not see the text file, you can contact your device manufacturer for the product key. Some manufacturers may provide the product key on an activation card.
This problem may be due to one of the following reasons:
- The product key that you entered is not linked with the account you are currently signed in to, but with another account. You may have purchased this key using a different account, or renewed the Norton subscription that is linked to an older account. So, enter the account credentials that you used during your Norton purchase. If you do not have access to the account, contact Member Services & Support for assistance.
- If you purchased your Norton subscription from a third-party website or vendor, your product key has been activated by someone else. Contact the vendor with your purchase receipt and request for a new product key.
‘The product key you entered is invalid. Please try again.’
This problem may be due to one of the following reasons:
1. The product key that you entered is incorrect, or is in invalid format. Check if you have mistyped the product key. The 25-character product key that you entered does not match the database that we maintain.
2. If you purchased your Norton subscription from a retail store, your product key has not been validated by the retail store where you purchased it. Return the subscription to the store with the receipt, and ask the store to validate your purchase. Your Norton product key is theft protected and the retail store needs to validate your purchase with Norton. After your product gets validated, you can use the product key and install your Norton device security product.
If you have an existing subscription that has Identity Theft features (ITPS) linked already, you will encounter this error. Norton doesn’t allow multiple subscriptions with Identity Theft features as it needs to be linked to one social security number (SSN). Gifting a second subscription is a great way to get your family or friends’ online lives secured.
