Help: Become an OnStar Member or Transfer an Account 

You may transfer your OnStar service plan if:

• You have an active, customer-paid OnStar service plan and account.
  
• The primary driver does not change.
• The new vehicle is equipped with OnStar hardware.
  

If you still own the vehicle listed on your service plan, the plan cannot be switched to a different driver.

Any service plan included with your vehicle purchase remains with the vehicle if it is sold or traded in with an active OnStar trial.

If you trade in your vehicle, return a leased vehicle or your vehicle is totalled because of collision damage, please call 1.888.4ONSTAR (1.888.466.7827) with your OnStar account number or Vehicle Identification Number (VIN). We will update your account status or transfer your service. You'll also need the date the vehicle was sold, traded or totalled. If you’re not eligible to transfer your service plan, a refund, if applicable, will be given for the remaining service plan time you purchased.

If at any time you wish to cancel your OnStar service, push your blue OnStar button to speak with an Advisor or call 1.888.4ONSTAR (1.888.466.7827). You cannot cancel your service online. If you let your service plan expire or choose to cancel it, your OnStar system will be deactivated. All services—including Automatic Crash Response and Emergency Services—will be shut off. Your vehicle won’t be able to connect with us for help, even in a crash.

When you create your OnStar account, you will set an OnStar PIN to access certain features. If you forget your PIN or would like to change it, visit your vehicle GM Account or push your blue OnStar button or call 1.888.4ONSTAR (1 888 466-7827) to speak with an Advisor.
