What should I know about using rip cards as mailable postcards?

Before you produce rip cards to send as mailable postcards, verify the mailing rules directly with USPS. The Post Office sets specific requirements for postcard size and materials, and rip cards do not always meet them.

• Check current USPS postcard dimension and thickness rules before production.
• Confirm the material and any perforations are acceptable for automated mail.
• You may need to place the rip card inside an envelope to qualify for mailing.
• Validating up front avoids a full run that cannot be mailed as designed.
