Every January, millions of Americans pause to honor the life and legacy of Dr. Martin Luther King Jr. Along with parades, community service projects, and public events, the federal holiday also affects the daily operations of many government services. One of the most searched questions during this time is simple but important: is the post office open on MLK Day?
For 2026, Martin Luther King Jr. Day is observed on Monday, January 19, and the answer matters for anyone expecting mail, sending packages, or planning a visit to a local post office. Below is a complete, up-to-date guide to how the holiday impacts USPS operations, delivery schedules, and what options remain available.
Understanding Martin Luther King Jr. Day as a Federal Holiday
Martin Luther King Jr. Day is one of the officially recognized federal holidays in the United States. It is observed on the third Monday of January each year and is intended to honor Dr. King’s role in the civil rights movement and his lasting impact on American society.
Because it is a federal holiday, most government agencies suspend normal operations for the day. This includes federal offices, courts, and the U.S. Postal Service. While some private businesses remain open, services tied directly to the federal government usually follow a holiday schedule.
Is the Post Office Open on MLK Day in 2026?
No. On Monday, January 19, 2026, all U.S. Postal Service retail locations will be closed in observance of Martin Luther King Jr. Day.
This means:
- Post office counters will not be open to the public.
- You will not be able to purchase postage in person.
- Package drop-off that requires clerk assistance will not be available.
- Passport services and in-office appointments will be suspended for the day.
Normal business hours will resume nationwide on Tuesday, January 20, 2026.
Mail Delivery Schedule on MLK Day
Along with retail counter closures, regular mail delivery will also be paused on MLK Day.
What Will Not Be Delivered

If your mail or package was scheduled to arrive on Monday, January 19, it will instead be delivered on the next business day.

Can You Still Access USPS Services on MLK Day?

Why the Post Office Closes on MLK Day

- New Year’s Day
- Memorial Day
- Independence Day
- Labor Day
- Thanksgiving Day

The holiday provides postal employees with a day of observance and aligns mail operations with federal standards.

- Many FedEx Office locations remain open with reduced hours
