The state of Illinois is no longer sending out the vehicle sticker reminder letters (see the link below for state website). However, you can sign up to receive electronic reminders via e-mail, which may allow you to avoid having to go to the DMV to pick up the stickers. When signing up, you will need your current Registration Identification Card.which lists the Registration ID and the PIN Number required to set-up reminders.
