Tag 191, Domestic and International Ballots

The Postal Service recommends the use of green Tag 191, Domestic and International Ballots, to identify trays and sacks that contain ballot mail. Although use of the tag is optional, it provides greater visibility to containers of ballot mail as they move through Postal Service processing and distribution operations.

Tag 191 may only be used to identify ballot mail addressed for domestic or international delivery. The tag cannot be used to identify containers of other types of Election Mail such as polling place notices, voter registration notices, or other election-related materials. Tag 191 may not be used for Political Mail.
