Letter-Size Booklets — Reminder


We provided final requirements for letter-size booklets mailed at automation and machinable letter prices in the April 15 Federal Register, New Standards for Letter-Size Booklets.” The new standards are effective September 8 and are intended to reduce damage to mail and eliminate the use of alternative processing methods for these pieces.


“Booklets” are mailpieces with a bound edge and include sheets fastened with at least two staples in the manufacturing fold (saddle-stitched), perfect bound, pressed-glued, or joined together by another binding method that is automation-compatible and produces an end where pages are attached. Booklets are generally open on three sides before sealing, like a book.


In general, booklets must be uniformly thick. Large, bound booklets that are folded for mailing, also called “quarter-fold” booklets, qualify for automation and machinable prices if the final mailpiece remains nearly uniform in thickness.


We encourage mailers to become familiar with the new standards, which include requirements for securing open edges, and begin preparing for the change. Please contact your local manager of Business Mail Entry with any questions.
