Your Quick Guide to
Postal Regulations

Let us help you choose the right Wafer Seal to meet Postal Regulations.

To receive the lowest possible mailing rates, follow these postal rules:

  • For booklet-type newsletters (multiple sheets of folded paper), fold along the bottom and close with three 1½" Wafer Seals.
  • Place two Wafer Seals on the leading (right) edge and one on the trailing (left) edge. Click "Learn More" to see a handy diagram.
  • The two top Wafer Seals should go within 1" of the top edge, and the other should go ½" from the bottom.
  • For single folded sheets of 8½" x 11" paper, the fold should be along the bottom, with one Wafer Seal placed along the open edge, in the middle.
