To require the United States Postal Service to notify postal customers and relevant officials when operations are temporarily suspended at a post office, and for other purposes.

HR 8303 requires the U.S. Postal Service (USPS) to notify customers and local officials when a post office temporarily closes. For planned closures, USPS must provide at least 60 days' notice detailing the reason, expected closure/resumption dates, and replacement services (like nearby retail access or mail handling), while unplanned closures require 14 days' notice. The bill mandates USPS to offer replacement retail services (such as box sales and mail access) within 10 days, in the same geographic area if possible, and to allow public comments on the closure. This applies to all temporary closures starting after the bill's enactment, directly affecting USPS operations, customers, and local representatives (e.g., mayors, congressional members).
