3-8 Handling, Content, and Extra Service

Mailers may use certain markings to identify handling, content, and extra service. The Postal Service does not permit unauthorized markings not designating price, class, address, handling, content, or extra service. Mailers may not place extraneous information next to or directly under the last line of the delivery address, because such information might be confused with ZIP Codes.
