The State of Maryland
does not require photo IDs. You are generally not obligated to provide one to election judges. Unless:
Identification
Q: Do I need to show identification before voting?
A: It depends. You will be asked to provide identification if:
You are voting for the first time in Maryland;
You registered to vote by mail on or after January 1, 2003; and
You have not previously met the identification requirements of the federal Help America Vote Act.
If you registered to vote by mail after January 1, 2006, you most likely satisfied the identification requirement during the registration process. If you did not satisfy the requirement, your County Board of Elections will have notified you and requested information to satisfy the identification requirement. (See list below.)
You can satisfy the identification requirement by providing one of the following:
Your driver's license number, MVA-issued ID card number or at least the last four digits of the your social security number, and we will attempt to verify this number with MVA or the Social Security Administration. You will be contacted if election officials were unable to verify the information.
A copy of a current and valid photo ID (i.e., Maryland driver's license, MVA-issued ID card, student, employee, or military ID card, U.S. passport, or any other State or federal government-issued ID card).
A copy of a current utility bill, bank statement, government check, paycheck or other government document that shows your name and address.
If you do not satisfy the identification requirement before voting for the first time, you will be required to present identification when you vote.
