5-4 Postage Required for Lawful Private Carriage of Letters

Determining the amount of postage payment required for private carriage can be done in different ways based on different circumstances. In some instances, the Postal Service may review the private carrier’s records to determine the required amount. In other cases, postage samplings will have to be performed until the Postal Service is satisfied that it has determined an amount equal to that which the Postal Service would have been entitled to had the letters been carried in the mail. When letters are aggregated for delivery to a single addressee, the amount of postage required is based on the weight of the mailpiece, not on the weight of each letter enclosed in the mailpiece. Once an amount of postage is established, it must be periodically reviewed for accuracy and adjusted if necessary.
