Depends how long ago your ID expired. If you are getting the normal ID you need 1 written signature ( cancelled checked or a major debit/credit card with your signature) and 1 proof of residency (bank statement less than 90 days or cancelled check or pay stub) if it's the RealID then 1 written signature and 2 proof of residency. Visit Cyber Illinois for more info of types of documents you need because there's a long line (unless you are there at 5am) and it's going to suck to wait in line to not have the correct documentation and be sent back. I'm saying because I went today and saw people being turned away for not having the correct documentation. So triple check before going.
Your expired state ID and $30 fee
Social security card or birth certificate and a piece of mail to update address
