What does PVI stand for in postal terms?

PVI in postal terms stands for Postage Validation Imprinter. This term refers to a device used to apply a postage label or stamp to a package or letter. The PVI is essential in ensuring that the correct postage has been applied and helps prevent postage fraud by validating the payment for the mailing service. This is particularly important in retail settings, where clerks need to ensure that every item sent through the mail has the appropriate postage affixed.

The PVI is designed to imprint a code that confirms the postage, allowing the postal service to track and manage mailings effectively. This is crucial in maintaining the integrity of mailing processes and ensuring that items are properly accounted for throughout their journey in the postal system. Other terms listed do not accurately capture this specific function related to postage and validation in the postal industry.
