Can I Transfer an Account?
If you're thinking of transferring an OnStar service plan, there are some important things to consider. You can transfer your service plan if you have an active, customer-paid OnStar service plan and account, the primary driver doesn't change, and the new vehicle is equipped with OnStar hardware.
To be eligible for a transfer, the primary driver must remain the same. This means if you sell or trade in your vehicle, you won't be able to switch the service plan to a different driver.
