Ballots cast in a mail-in election, or as a paper absentee ballot, or as a paper provisional ballot, must use a double-envelope paper balloting system, in which:
(1) The voter places the completed ballot inside the inner envelope;
(2) The inner envelope is sealed to prevent tampering, and no personally identifying marks are to be placed on the inner envelope;
(3) The inner envelope containing the completed ballot is placed in the outer envelope; and
(4) The voter provides sufficient identifying information on, or inserted into, the outer envelope to allow polling officers to verify the eligibility of the voter.
