Postage Evidencing Systems
Postage Evidencing Systems regulated by part 501 produce evidence of prepayment of postage by any method other than postage stamps and permit imprints. A Postage Evidencing System is a device or system of components that a customer uses to generate and print evidence that postage required for mailing has been paid. Postage Evidencing Systems print indicia, such as information-based indicia or intelligent mail indicia to indicate postage payment. They include but are not limited to postage meters and PC Postage systems.
