Is USPS open on MLK Day? No, Post Offices are closed and regular mail is not delivered. The next holiday falls on Monday, January 18, 2027, with normal service back Tuesday, January 19.
MLK Day is a federal holiday, and the Postal Service treats it like one. A few things still work, including Priority Mail Express, self service kiosks, and everything on usps.com. This page covers what runs, what stops, and how to plan around it.
Is USPS open on MLK Day in 2025, 2026 and 2027?
The holiday always lands on the third Monday of January. The federal list is published by the Office of Personnel Management, and USPS follows it.
| Year | MLK Day date | Normal service resumes |
|---|---|---|
| 2025 | Monday, January 20 | Tuesday, January 21 |
| 2026 | Monday, January 19 | Tuesday, January 20 |
| 2027 | Monday, January 18 | Tuesday, January 19 |
Is USPS open on MLK Day 2026? No. The closure was Monday, January 19, 2026, and USPS local releases said there was no mail delivery, caller service or Post Office Box service.
The same pattern applied on Monday, January 20, 2025. USPS state releases that year also announced Post Offices closed. Whenever the date changes, the answer stays the same.
The holiday is a Monday every year. That means the closure always sits next to a weekend, so many people lose three days of counter service in a row.
What is closed on Martin Luther King Jr. Day
Everything that depends on a staffed counter or a carrier route stops. USPS has used the same wording for years in its local releases.
- Retail counters at Post Offices are closed all day.
- Letter carriers do not deliver regular mail or packages.
- Caller service, where a business picks up its mail at the Post Office, does not run.
- Post Office Box service is listed as unavailable in the 2026 local notices.
Box access can vary by location. The national operations letters tell Post Offices to provide PO Box access “to the maximum extent possible”, which in practice means an unlocked lobby at some offices and a closed door at others, so collect anything time sensitive on Saturday or wait until Tuesday.
What still works on the holiday
A few services keep going, and they cover most urgent needs. None of them involves a Post Office counter.
| Service | Status on MLK Day |
|---|---|
| Self service kiosks | Open 24 hours at select locations, debit and credit cards only |
| usps.com | Stamps, labels, accounts and tracking stay available |
| Priority Mail Express | Moves as a holiday premium service where offered |
| Regular mail and parcels | No delivery and no pickup |
| Post Offices | Closed |
Self service kiosks
USPS says kiosks handle roughly 80 percent of typical counter transactions. You can weigh a package and buy postage for Priority Mail Express, Priority Mail, First-Class Mail and ground parcels. Kiosks are only at select Post Offices, so check the USPS locator before you drive over.
Priority Mail Express
USPS keeps Priority Mail Express moving on federal holidays as a premium service. That matters if you already have an Express label and a firm deadline. Drop it at a kiosk or a collection box, and confirm the delivery window when you buy it.
What the closure means for a long weekend
Because the holiday sits on a Monday, the last normal pickup before it is Saturday. USPS holiday operations letters tell staff on duty to check collection boxes, lobby drops and kiosks for overflow and to run full collections only where a cancellation is scheduled, so a letter dropped on Sunday may be gathered but is not postmarked and moved until Tuesday at the earliest. A package you ship Friday afternoon will usually sit over the weekend and the holiday as well.
Count business days, not calendar days. Friday to Tuesday is only two business days of movement, even though four calendar days pass. That is why a parcel can look stuck on Monday when nothing is wrong.
Will my mail still arrive on MLK Day?
Most of it will not. Regular letters and parcels wait until the next delivery day. For a Monday holiday, that day is Tuesday.
The calendar effect is simple. A package due on Monday arrives Tuesday. Tracking can show a delay without any real problem, because the parcel is simply waiting for a staffed day.
Informed Delivery goes quiet too. USPS sends no preview notifications on federal holidays, so an empty inbox on MLK Day is the schedule, not a missed delivery.
Use the Delivery Time Estimator to see how a holiday pushes a delivery date. Count Monday as a non delivery day, and the weekend before it as the usual weekend.
What to do if you need to mail something
Work backward from the holiday rather than hoping for a counter. These steps cover the common cases.
- Mail before the holiday. USPS said Saturday ran on regular hours before the 2026 closure, though counter hours vary by location.
- Print postage on usps.com and hand the parcel over on the next day that service runs.
- Use a kiosk for same day postage if you must ship during the closure, and expect pickup to start Tuesday.
- Pay for Priority Mail Express only when the deadline justifies it.
- Check any date sensitive shipment with the Postal Holiday Checker before you commit.
Do not plan on a holiday postmark. If a deadline depends on one, such as a tax filing or a legal notice, mail it before the closure and keep the receipt. The Postal Holiday Checker shows which dates around you are holidays.
Businesses and bulk mailers
Commercial customers have their own contact path. USPS tells them to ask their Bulk Mail Acceptance Unit about hours on the holiday. Anyone else can call 1-800-ASK-USPS for help.
How to confirm your own Post Office
The national pattern is firm, but local notices are the final word. USPS publishes a release for each state or district a few days before the holiday. The release lists the closure date, the kiosk options and the day service resumes.
Use the locator on usps.com to find a kiosk that is open around the clock. Not every Post Office has one, so look before you leave home. Kiosks take cards only, so carry a debit or credit card rather than cash.
How MLK Day compares with other USPS holidays
The closure rules are the same across the federal holidays. Only the dates change. Veterans Day follows the same pattern, as covered in is USPS open on Veterans Day.
Juneteenth works the same way, as explained in is USPS open on Juneteenth.
Labor Day does too, and the Labor Day delivery answer shows the details.
The weekend is a separate question. Saturday hours depend on the office, and the Sunday rules are different again.

Bottom line on MLK Day mail
Expect a quiet Monday. Counters, carriers and Box service pause, while kiosks, usps.com and Priority Mail Express carry on.
Is USPS open on MLK Day? Not in any way that helps a counter errand, so plan around Tuesday, January 19, 2027, as the first normal day.
