About the activation code

Activation code is a code that you receive on acquiring the premium license for Kaspersky Internet Security. The code is required for activation of the app.

The activation code is a unique sequence of 20 letters and numerals in the format xxxxx-xxxxx-xxxxx-xxxxx.

Depending on how the app is purchased, the following options are available for receiving an activation code:

  • If you purchase the boxed version of Kaspersky Internet Security, the activation code is specified in the documentation or on the box that contains the installation CD.
  • If you purchase Kaspersky Internet Security at an online store, the activation code is sent to the email address that you specify when ordering the product.

The license term is calculated from the date of activation of the app. If you acquire a license intended for the use of Kaspersky Internet Security on several devices, the license term is calculated to begin the moment you first apply the activation code.

If you lose or accidentally delete your activation code after activation of the app, contact Technical Support at Kaspersky Lab.
