Self-Mailer postal regulations set to change on January 5, 2013
Categories: Postal Updates
Come on! What good is another set of changes? Well, the USPS says this will reduce damage to your mail (and stop their sorting equipment from jamming). So, here is what you need to know.
First, the definition of a self-mailer: It’s a folded piece that is letter-sized, isn’t mailed in an envelope and doesn’t have a binding. If it has staples in the fold, it is a defined as a booklet, not a self-mailer, and booklets aren’t affected by these changes.
Now, the new regulations document is long and complicated. But, the majority of you only need to know the following:
- Final folds on the top will no longer be allowed.
- Self-mailers that now only need one tab on the top will need two.
- Quarter-fold self-mailers will need to be at least 70# book (=28# bond).
- No tabs will be allowed on the bottom.

Tri-fold and quarter-fold flyers and newsletters will need two tabs next year, not just one.
- The final folded panel creates the non-address side of the mail piece by folding from bottom to top, or lead to trail edge, as shown in the following illustrations.

For tri-folded self-mailers, the mailing address must be on the middle panel, with the final fold creating the non-address side.

What the post office calls oblong self-mailers must have the final fold on the right side, or ‘leading edge’. Two options for tabbing are shown.
There are other changes as well. We’ve summarized most of them in the following chart. Be sure to forward this post to your designer and printer.
And please, when you finish your self-mailer designs, email a PDF of it to us to check for compliance with USPS regulations prior to printing. We’ll make sure you don’t run afoul of the USPS!

Some less common self-mailer designs are too complex to cover in a short table. So, if your design is different than the ones in the table, contact us to discuss it. Or, if you’re brave, here’s the Postal Services reference PDF that covers all the changes.

Thanks so much for digesting and making available the new tabbingrequirements.
The USPS’s 5 pages of explanation bogles the mind!!
Have a good year!!
What everyone is missing is how this effects the paper industry. 60# offset such as Astrobright colors are no longer allowed for single page mailings! Wow – What does the paper mill think about that? Most paper suppliers stock a lot of choices in 60# colors but very few 70#. What becomes of all that inventory? Try to find 8.5 x 14 paper in 70# offset – Not a lot of choices! Bottom line – the Post Office change just increased the tonnage their trucks have to move and the bulk. Both will add to their expenses – How does that help?
Good question Mark. From the USPS point of view, heavier paper stock and more wafer seals mean their high speed sorting machines will have fewer jams, meaning they can process the mail with fewer facilities and fewer people. When you are loosing money at the rate they are, and constrained by Congress on what they can change, running the machines at full speed becomes the focus.
I understand how the heavier paper may make it easier to process – The point I was trying to make was that millions of dollars of paper have been deemed “unacceptable” by the Post Office making that change. As a print shop owner I have over 125,000 sheets of paper on my shelves that cannot be used for a mailer…I think that is concern not only for myself but for the printing industry.
During the comment phase during 2011 before the rule was finalized, the USPS solicited comments. From the final rule published last year in the Federal Register, here is the USPS comment about the change in paper weight:
One commenter suggested that the
paper basis weight is unreasonably high.
The basis weight of paper is one of the
major factors that affect the
machinability of a mailpiece. Pieces
prepared with lower paper weight were
unable to withstand the rigors of
automation processing, resulting in
higher rates of damage and jams and a
diversion to more costly flat sorter and
manual processing methods. We retain
the paper basis weights as proposed.
