Even when brick-and-mortar facilities are closed, some post office services are available online 24/7, including on holidays. With a USPS.com account, you can order stamps, print shipping labels, order boxes and other mail supplies, and request package pickups.
Stamps are also sold at most major supermarkets, pharmacies and office supply stores, which are open on some federal holidays.
FedEx and UPS holidays
Other major delivery companies set their own schedules and operate partially or in full on some federal holidays. Most FedEx and UPS services will operate normally on Martin Luther King Jr. Day, and their retail locations will be open.
