What information is required on a postcard design if I'm using non-profit postage indicia?

When you print a postcard for non-profit mailing, USPS needs the address side kept clear so mailing details and the indicia can be placed correctly. Design around those reserved areas so nothing important is covered or rejected at the mail stream.

• Address block: leave the designated area (typically about 2.5 x 4 inches) free of artwork
• Indicia corner: keep the upper-right postage indicia area clear
• Permit information: set up your non-profit mailing permit with the mailing service
• Clearance: avoid placing text or graphics where the barcode and address will print

Requirements can vary by card size, so confirm the exact layout for your piece before you submit the file.
