What Characteristics Should I Look for That Might Suggest a Suspicious Item in My Mail?

Under certain circumstances, you should exercise more caution if you are concerned about the receipt of suspicious items. Be alert to mail pieces which are unexpected or sent by someone unfamiliar to you. The following characteristics may also dictate caution when handling an unknown mail piece:

  • Items addressed to someone no longer with your organization or otherwise outdated.
  • Items that are handwritten and have no return address, or have one that can't be verified as legitimate.
  • Items containing restrictive endorsements, such as "Personal" or "Confidential".
  • Items of unusual weight relative to their size, or that are lopsided or oddly shaped.
  • Items which are sealed with excessive amounts of tape.
  • An item containing a postmark which does not match the return address or bears an excessive amount of postage.
  • Mailpiece is leaking an unknown powdery substance.
