Fleet Activation

Below you'll find instructions for activating OnStar service in your Fleet vehicles.

Planning to activate OnStar on numerous vehicles? Save time and effort by enrolling in an OnStar Fleet Master Account, which allows you to complete one Subscription Service Agreement for all of your Fleet vehicles. Doing so also allows you the opportunity to provide OnStar with your roadside and accident assist phone numbers, if applicable.
