I’m eloping in July and plan on changing my last name. My parents don’t know. Do I need to report my name change to SS and the DMV?

Best wishes on your marriage! If you decide to change your name, then yes, you will need to change your driver's license and your Social Security card information to reflect the correct name. You will generally need a certified copy of your marriage license for that, along with a certified copy of your birth certificate.
