The main purpose of this legislation, known as the Vote by Mail Tracking Act, is to improve the security and tracking of mail-in ballots used in elections. It aims to ensure that every mail-in ballot can be tracked throughout the postal system, making the voting process more transparent and reliable. Key provisions of the Act require that any mail-in ballot envelope must include a Postal Service barcode that allows for tracking. This barcode must meet specific standards set by the Postal Service.
