POSTAL TERMS, ABBREVIATIONS, AND
You should be aware that most of the publications used by postal clerks have lists of terms,
abbreviations, and acronyms defined in an appendix. The U.S. Postal Service (USPS) and the U.S.
Navy (USN) use these abbreviations in postal messages and correspondence on a daily basis. Along
with terms, abbreviations, and acronyms, we also use many United States and international cities,
port, airport, and air carrier codes (usually three-letter codes) to get the mail transported to its
destination(s). There are also numeric codes assigned to various air carriers. In addition to the terms,
abbreviations, and acronyms we will show in this appendix you may find additional postal terms,
