Counterfeit & Fraud Prevention FAQs
To address unpaid and counterfeit postage, the USPS will validate payment documentation in real-time beginning August 1, 2024. Packages that are unmanifested at the time of the first scan at a USPS facility will be intercepted and subject to disposal. These packages will not reenter the mail stream and Shippers will not be reimbursed. This document details FAQs concerning this August 1 Payment Check. USPS wants you to be as current on the new changes as possible so we will be updating this document periodically.
