Balloting Materials Postage

Today the Federal Register published our Domestic Mail Manual (DMM®) final rule that revises mailing standards to require all ballot types to include in their balloting materials a marking indicating that the proper amount of postage must be paid. The balloting materials must also indicate the specific amount of First-Class Mail® postage for the return of ballots, unless they are mailed under certain specified exceptions.

The effective date is October 7, 2013.
