Good to know about creating a MyDMV account  . Will MyDMV account be associated with my current NY.govID username?
Actually yes, your MyDMV account will be associated with your current NY.govID username and you will not need to create a new username.
What should I do if I request a new license and it has not arrived yet?
You must wait until you receive your new document to create your account. You cannot create a MyDMV account if you have never been issued a New York State non-driver license, permit or ID.You can confirm or change your address online
