Make sure your post card promotions yield
to the bar code clear zone!

When planning the address side of a post card design or any mailing, it's important to know the postal regulations concerning the bar code clear zone. Bar codes are a series of vertical lines of two different heights. The postal service prints a bar code in the lower right corner of most mail to speed the sorting and delivering of mail to its destination.
The bar code clear zone is defined by these boundaries:
       Right: Right edge of the mailpiece.
       Left: 4¾" from the right edge of the mailpiece.
       Bottom: Bottom edge of the mailpiece.
       Top: 5/8" from bottom edge of the mailpiece.
 Bar Code Zone

If copy is placed in this zone, it may be covered with an adhesive strip by the USPS to spray on the destination bar code. To make sure this doesn't happen with your cards or other mailers, we recommend you check your layout against these specifications or with your local post office.
