Enter your Norton product key

To install your Norton device security product on the current device, type your product key and then click the arrow button.

The product key is a 25-character alphanumeric string that is shown in five groups of five characters each, separated by hyphens. The location of the product key varies depending on how you acquired the product.

You need the product key only to register and install your protection for the first time. If you are trying to install on a new device or reinstall on an existing device, you can download and install the product from your account. For detailed steps, read Download and install your Norton device security.

'The product key you entered has already been activated' or 'associated with another account'

This problem may be due to one of the following reasons:

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.

Other product key related errors

'You already have an existing membership...'

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. You can either gift the new subscription to a family member and/or call Member Services & Support for further advice.

'You are requesting a non-downloading product'
