Suspicious Mail

Dangerous mail includes mail bombs, hoax devices, suspicious substances, or any matter that may cause harm. The likelihood of anyone receiving a harmful biological or chemical agent is extremely remote. Postal Inspectors within the Dangerous Mail Investigations Program are specially trained to recognize the common characteristics of suspicious mail and use an array of specialized screening equipment to identify and mitigate threats to postal infrastructure, its employees, and the general public.
