In that case you will need to wait for it to arrive before you can create a MyDMV account. You can still change your address, though.

honestly no, the answer you gave me was somewhat incomplete. I need help with the document number of the photo, how do I know if I am doing it the right way? could you advise me?
First, make sure you enter your photo document number correctly (exactly as it appears on the email) because It is very easy to mistake the following:  the number 1 for letter the Is  the number 0 for the letter O  the letter Q and the letter O  the number 5 and the letter S  the number ' 8 ' and the letter ' B '
