Your return address should always be either on the top left corner of the product, or the top left corner of the mailing panel. If you put your return address anywhere else, it could be accidentally used as your mailing address during scanning. A return address is required for first class mailing.
All letter class mail must be mailed in landscape orientation. Flat sized mail can be done either landscape or portrait, but portrait is the most commonly used orientation.

5.5 x 8.5 booklets qualify as Letter-Class. The mailing panel (delivery address) must be set up so the spine is on the bottom. Or, for landscape booklets, the spine must be on the leading edge (right hand side). Please refer to our free downloadable mailing templates here.
8.5 x 11 Multi-Page products qualify as Flat-Class. The mailing panel (delivery address) can be anywhere in the top half of the piece. Please refer to our free downloadable mailing templates here.

On the back middle panel, orient your mailing information where the fold is on the bottom and the opening is on top. Please refer to our free downloadable mailing templates here.
For products over 6” x 11” (or Flat Class Mail) your mailing panel must be within the top half of your product and be large enough to accommodate the address and intelligent-mail barcode. Avoid putting any text near the address area that could be misread as address data. Please refer to our free downloadable mailing templates here.
The minimum size is 3.5 inches wide, but PrintingCenterUSA prefers recommends 3.75 inches so we can easily fit an intelligent-mail barcode. For example:
For products over 6” x 11” (or Flat Class Mail), yes, as long as the address area is large enough to accommodate your address and intelligent-mail barcode. Avoid putting any text near the address area that could be misread as address data. Please refer to our free downloadable mailing templates here.
For postcards and products up to 6” x 11” (Letter Class mail) you should not have art below the address area.
