The MAILS Act requires the U.S. Postal Service to improve how it communicates with local communities about post office relocations and changes to service locations. The bill mandates that the Postal Service establish a formal process within 90 days for local officials to request new post offices and sets strict notification requirements for temporary relocations, including notifying elected officials at least 30 days in advance and holding public presentations at least 15 days before a move. For any temporary relocation lasting longer than two days, the Postal Service must collect and consider community input, and for relocations exceeding 180 days, it must report to Congress and affected representatives within 30 days of the move. The legislation affects postal customers and local governments across the country by giving them a formal voice in post office decisions, with no new federal funding specified in the bill.
