The Periodicals class of mail is designed for newspapers, magazines, and other periodical publications whose primary purpose is transmitting information to an established list of subscribers or requesters. Periodicals must be published at regular intervals, at least four times a year from a known office of publication, and be formed of printed sheets. There are specific standards for circulation, record keeping, and advertising limits. There are special lower postage rates for Nonprofit and Classroom Periodicals.

There is a formal application procedure[1] and a nonrefundable application fee ($510) to become authorized for Periodicals mailing privileges. Talk to your business mail entry staff[2] for advice on becoming a Periodicals mailer.
