Audit Report – HR-AR-14-001 – May 28, 2014
The outside of an envelope can be an effective tool in law enforcement investigations. In fiscal year 2013 alone, the Postal Inspection Service processed about 49,000 mail covers that were used to protect national security, locate fugitives, obtain evidence, or help locate stolen property.
But significant privacy issues govern the handling of mailpieces and the information on them. For that reason, the Postal Service and Postal Inspection Service must follow detailed procedures before allowing a mail cover.
