If business reply cards or envelopes are distributed from a central office to be returned to branches or dealers in other cities, one permit obtained from the post office where the central office is located may be used to cover all.

(5) Business reply cards, envelopes, and labels may be distributed:

(i) In any quantity for return by surface or air mail. (See § 26.1 of this chapter for airmail rate.)

(ii) To any post office in the United States and its Territories and possessions, including military post offices overseas; except in the Canal Zone, where they may not be returned without prepayment of postage. They should not be sent to any foreign country.

§ 22.2 Qualifications for second-class privileges-(a) What may qualify—(1) Mailable publications. You may mail only newspapers and other periodical publications at the second-class rates. The copies may not contain obscene, treasonable, lottery, or other kinds of material that would cause them to be nonmailable under the provisions of Part 14 of this chapter.

(2) With or without general advertising. All publications that meet the basic qualifications explained in paragraph (b) of this section may carry general advertising. The publications of the institutions and societies specifically named in paragraph (c) of this section must meet all the basic qualifications except the requirement of a paid subscription list. They are excused from having a paid list only when they do not carry general advertising. Those which carry general advertising must have a paid list.

(b) Basic qualifications—(1) Regular issuance. Publishers must determine the number of issues they will publish each year and adopt a statement of frequency that will show at what regular intervals the issues will appear. Examples of statements of frequency are:

Daily.
Weekly.

Monthly.
Quarterly.

Monthly except during July and August. Semiweekly.

Biweekly.

Semimonthly.

Weekly during school year.

Four times a year in January, February, October, and November.

A publication may not be published under a frequency that provides for less than four issues each year. Issues must be published regularly as called for by the statement of frequency. Publishers may change the number of issues scheduled, and adopt a new statement of frequency by filing an application for second-class reentry. (See § 22.3 (d).)

(2) Issuance at known office. Publications must be issued and mailed at a known office or place of publication. A known office or place of publication is a public office where the business of the publication is transacted during the usual business hours.

Offices for the transaction of business may be maintained at more than one place, but mailings may be accepted at the second-class pound rates only at the post offices where original or additional mail privileges have been authorized.

All copies printed and circulated either by mail or by the publishers' carriers, and at the second-class pound rates or the transient rate, are considered in determining whether a publication is designed for free circulation.
