What to Bring

For identity, bring one primary document such as a valid U.S. passport, an out-of-state driver’s license, a U.S. military ID, or a federal or Michigan government employee photo ID. For your Social Security number, bring your Social Security card, a W-2, an SSA-1099, or a pay stub showing the full nine-digit number. For Michigan residency, bring two documents dated within the last 90 days, such as a utility bill, bank statement, insurance policy, pay stub with your address, or a lease.7Michigan Department of State.
