Mail delivery continues during a government shutdown. The U.S. Postal Service (USPS) operates as an independent, self-funded agency and is not funded by congressional appropriations, so it is not affected by the shutdown. Post offices remain open, letter carriers work and are paid as usual, and normal mail services continue without interruption despite the federal government shutdown starting October 1, 2025.
