They're at it again. New changes in postal requirements could affect your mail piece. Check before you design!
It's important to stay up-to-date about new postal regulations that could affect any current or future mail piece. There have been some design changes that affect locations of tabs and addresses, so you will want to check them if you are re-using a design for mail or creating a new design. If the design does not meet the Postal Service’s requirements, then the cost of mailing the piece will go up.
Some of the changes that we see on common mail pieces include the locations of binds or folds, tabs or glue and address panels.
Here is a link (below) to information available on the Postal Service's website, although it's probably best to go into an office or speak with your printer for further information.
See the info that's available online.
