does the post office work on mlk day

[Gimli]

Yes, Martin Luther King Jr. Day is a federal holiday in the U.S., and the United States Postal Service (USPS) observes it. This means post offices are generally closed, and there is no regular mail delivery on this day. Customers should plan accordingly, as services resume the following business day.

On MLK Day, USPS does not perform standard mail or package deliveries. Priority Mail Express may still operate in limited cases, but most deliveries and pickups are paused. Customers relying on time-sensitive shipments should consider alternate shipping options or plan around the holiday schedule to avoid delays.

Since post offices are closed on MLK Day, customers cannot access in-person services such as mailing, purchasing stamps, or package drop-offs. To avoid disruption, plan ahead for mailings, use online shipping tools, or schedule package pickups on surrounding business days when USPS resumes normal operations.
