4-4.4 Required Markings

The sender must prominently mark the outside covers or containers of letters carried under this suspension with the words “Extremely Urgent” or “Private Carriage Authorized by Postal Regulations (39 CFR 320.6)” or with a similar legend identifying the letters as carried pursuant to this suspension. In addition, each outside container or cover must show both the name and address of the carrier and the name and address of the addressee. Carrier records must be sufficient to show that the delivery of the letters was completed within the applicable time limitations, if carried under the authority of part 4-4.2, and must be made available for inspection at the request of the Postal Service. The required records may be either in the form of notations on the containers or covers of any letters asserted to be carried under this suspension or in the form of records kept by employees of the actual times they pick up and deliver such materials.
