Do you need to submit ID with your ballot?

No, but the signature on the vote-by-mail ballot must match the voter registration signature.

If you registered to vote by mail and are voting by absentee ballot in your first federal election, you must enclose a copy of your photo ID or document bearing your name and residence address in the envelope with your voted ballot.
