5-1 Authorized Markings

5-1.1 General

The DMM and the IMM provide information on addressing standards and endorsements required for each class of mail and service. Special markings are also required for certain restricted items. Contact a business mail entry unit for guidance (see DMM G042 for addresses).

As a rule, the following markings are permitted on the outside of a mailing container:

• Return and delivery addresses.

• Ancillary service endorsements for address correction, forwarding, etc.

• Special service endorsements.

• Class of mail marking.

• Handling instructions.

5-1.2 AddressExample of affixing labels to the container to be mailed.

Each package must show a delivery address on the mailing container or on a label affixed to the container. In addition, a return address must be placed in the upper left corner of the container (or address label). The addresses should meet postal address format standards. Publication 28, Postal Addressing Standards, provides detailed information about address formats and requirements.

Inside the mailing container, the names and addresses of the sender and addressee and a description of the enclosed items should be included. This precaution can aid in the delivery of a parcel if the addresses on the outside of the container become unreadable or the items become separated from the container.
