You’re standing there with a stack of envelopes or a bulky Amazon return, wondering if the blue box is going to be emptied or if the lobby doors are even unlocked. It’s Saturday, January 17, 2026. The big question—was us post office open today—actually has a pretty straightforward answer, but the "why" and the "how" of weekend mail can be a bit of a maze if you aren't careful.
The short version? Yes, the US Post Office was open today. Since today is a standard Saturday, most retail locations across the country followed their usual weekend hours. However, those hours are notoriously finicky. While your main downtown hub might stay open until 3:00 PM, that small branch tucked inside a local grocery store or a tiny rural outpost might have shuttered its windows by noon.
Why Saturday Matters More This Week
Honestly, the reason people are searching for this today is likely because of what’s happening in 48 hours. Monday, January 19, 2026, is Martin Luther King Jr. Day.
Because MLK Day is a federal holiday, the USPS will be completely locked down on Monday. No regular mail delivery. No retail counter service. This creates a "bottleneck" effect where everyone rushes to the post office on the Saturday before the long weekend. If you went today, you probably noticed a longer line than usual.
Basically, the USPS operates on a strict federal calendar. Even though the "holiday" is Monday, the operational ripples start today. Carriers are pushing to clear out as much volume as possible because they know that by Tuesday morning, the mail sort facilities will be overflowing with three days' worth of letters and parcels.
The Saturday Schedule: What Stays Open?
Don't expect your neighborhood post office to keep the same hours as a Starbucks. USPS retail hours on Saturdays are almost always truncated.
- Large Urban Hubs: These typically open around 8:00 AM or 9:00 AM and close between 1:00 PM and 4:00 PM.
- Small Town Branches: You’re lucky if these stay open past 11:00 AM. Many close precisely at noon.
- Self-Service Kiosks: These are the unsung heroes. In many larger lobbies, the APC (Automated Postal Center) is available 24/7, even if the actual counter is closed and the lights are dimmed.
If you’re wondering about delivery, your mail carrier was likely out on the streets today. Residential and business delivery continues as normal on Saturdays for all mail classes. It’s only Sunday where things get weird—unless you’re receiving a Priority Mail Express package or certain Amazon deliveries, Sundays remain a "dark" day for the blue trucks.
Was US Post Office Open Today for All Services?
There is a distinction between the door being open and "full service" being available. Even if the retail counter was open today, some specific services might have been limited.

For instance, passport applications often require a separate appointment, and many offices stop accepting those an hour before the retail counter closes. If you were hoping to get a money order or ship something via Registered Mail (the ultra-secure service with the red tape), you had to beat the clock before that final Saturday "sweep."
The USPS actually reported some interesting data recently regarding their 2026 operational efficiency. Postmaster General David Steiner noted in a January 15 press release that on-time delivery scores have improved by 6.4 percentage points compared to last year. This is partly due to the massive logistics overhaul and the "Delivering for America" plan that has been slowly rolling out over the last few years.
What Happens If You Missed the Window?
If you found the doors locked or the line too long, you aren't totally out of luck.
First, check the Self-Service Kiosks. You can weigh packages, buy postage, and drop off anything that isn't a restricted item. Second, remember that private carriers like FedEx and UPS operate on different schedules. While USPS is closed this coming Monday for MLK Day, FedEx typically keeps most of its retail locations and delivery routes moving, though with some modified service levels.
Kinda frustrating, right? The government shuts down for the federal holiday, but the private sector keeps the gears turning. If you have an urgent contract that needs to be there by Tuesday, using the Post Office on a Saturday before a Monday holiday is a gamble. Priority Mail sent today (Saturday) likely won't even leave the regional sorting facility until Tuesday evening, meaning a Thursday or Friday arrival is more realistic.
Actionable Next Steps
To avoid getting stuck in the "is it open" loop in the future, here is how you should handle your mail on a Saturday:
- Use the USPS Locator Tool: Don't guess. Go to the official USPS website and filter by "Location Type" and "Refine Search" to find "Self-Service Kiosks." This ensures you can at least ship a package even if the clerk has gone home.
- Check the "Last Collection" Time: Every blue box and retail drop-off has a placard showing the last pickup time. On Saturdays, this is often as early as 10:00 AM or 12:00 PM. If you drop it after that, it sits there until Monday (or Tuesday, if Monday is a holiday).
- Prepare for the MLK Day Gap: Since the post office is closed Monday, January 19, avoid sending perishables or time-sensitive documents today unless you are paying for Priority Mail Express, which is the only service that ignores most holidays.
- Digital Alternatives: Remember that you can print postage at home via Click-N-Ship. This allows you to skip the retail line entirely and just drop your package in a designated bin or schedule a pickup for the next available delivery day.
