In 2022, the United States Postal Service (USPS) processed an average of 421 million pieces of mail daily. The volume of letters and packages makes security imperative to keep both postal workers and mail recipients safe.
According to a RaySecur report, nine out of 10 mail-related incidents utilized small mail items (50% letters and 41% parcels). White powders and drugs are the most common substances found in mail security incidents at 55% of all tracked threats in the U.S. Of those powders, 27% were unknown substances and 28% were determined to be drugs or narcotics.
