Mailings are verified at origin by Postal Service employees assigned to a detached mail unit (DMU) at a mailer’s plant or at the business mail entry unit (BMEU) at the origin Post Office serving the mailer’s plant. Throughout the remainder of this publication, the term “origin office” refers to the location where the mailing was verified and accepted.
Following acceptance and postage payment, PVDS mailings are then released to the mailer for transportation to destination Postal Service facilities. The shipment is deposited at the destination Postal Service facility by the mailer where it is received as mail by Postal Service employees and released for processing.
