First-Class Mail® service provides security, speed, and affordable rates for highly important and time-sensitive mail.
Tampering or interfering with U.S. Mail® is a federal crime that is enforced by one of the nation’s oldest law enforcement agencies — the United States Postal Inspection Service.
Green Tag 191 is recommended for use with trays and sacks containing official ballot mail and red Tag 57 is recommended for use with PCM. Use of these tags provides greater visibility to mail trays or sacks during Postal Service handling.
