Activate account for Subaru vehicle
All you need to set up your MySubaru account is an active email account and Subaru Vehicle Identification Number (VIN). Your Subaru's VIN can be found on your vehicle registration or located on the driver's side dashboard and the plate on the driver's side door frame.
If you purchased your Subaru through a private sale, please contact Subaru Customer Support at (800) SUBARU3. You will need to provide a copy of your registration information to prove you own the vehicle.
