The “blackout” period for Franked Mail mass mailings takes effect Wednesday, Aug. 8.

Franked Mail is official correspondence sent by members of Congress and other authorized users.

These mailpieces have the member’s facsimile signature — the frank — in the upper right corner of the envelope or label instead of a postage stamp. The frank includes “M.C.” (member of Congress) or “U.S.S.” (U.S. Senate).

Members of Congress are banned from sending Franked Mail mass mailings 90 days before a general election. Mass mailings contain 500 pieces or more.

The Postal Bulletin’s July 19 edition has more information about Franked Mail.
