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 Latin characters and numbers in the format xxxxx-xxxxx-xxxxx-xxxxx.

Depending on the way of purchasing the application, the following options are available for receiving an activation code:

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

The license validity period is calculated from the date on which the application is activated. If you have acquired a license intended for the use of Kaspersky Internet Security on several devices, the term of the license starts counting down from the moment you have first applied the activation code.

If you have lost or accidentally deleted your activation code after activation, contact Technical Support Service at Kaspersky Lab.
