Unfortunately, no relevant information is found.
so what do I do if I don't know my ID number and I can't change my info online?
You will need to wait for your ID to arrive before you can create a MyDMV account.  You can still change your address by mail.
so I can't do anything until I get my ID then I have to wait again to make changes and wait yet again for a newer ID? sounds like too much to do for a simple thing
