Mail Tips


  • Address interdepartmental mail with legible complete department names, no abbreviations.
  • Exposed metal fasteners are unacceptable.
  • Request a reusable fabric mail pouch from Mail Services if you have regular interdepartmental mail between two departments.
  • If using letter-size envelopes for interdepartmental mail, please put a red check in the upper right hand corner of the envelope and separate from other U.S. mail.
  • When addressing mail to a location outside the district please use plain manila envelopes.
  • All mail to be posted must be in clear plastic packets or in a covered box for weather protection during transport to Mail Services.
  • No personal mail or packages can be sent through the delivery system.
