Most post offices close between 5 PM and 5:30 PM on weekdays. That is the honest average, not a guarantee. The real answer to what time does USPS close depends on the specific branch.
A small rural office might lock the door at 4:30 PM. A busy city station can stay open past 6 PM. The staffed window and the lobby itself often run on separate schedules too, and this guide covers both.
What time does USPS close?
On a typical weekday, the staffed retail counter closes somewhere between 5 PM and 5:30 PM. Some branches close as early as 4:30 PM. A few big city or airport stations stay open until 6 PM or later.
There is no single national closing time. USPS sets counter hours branch by branch, based on local traffic, staffing, and how many other counters serve the same area. A branch inside a strip mall next to three other post offices often keeps shorter hours than the only office in a rural county.
The only reliable way to get an exact time for your address is the location locator.
Use the USPS location lookup tool and search your ZIP code. Retail hours show up next to the lobby hours. That single search settles what time does USPS close for your exact branch, not the national average.
| Location type | Typical retail close | Typical lobby or kiosk access |
|---|---|---|
| Small town branch | 4:30 PM to 5 PM | Often closes with the counter |
| Suburban branch | 5 PM to 5:30 PM | Lobby open into the evening at many locations |
| Large city or airport station | 6 PM to 7 PM, occasionally later | Kiosk access often runs 24 hours |
That kiosk distinction matters more than most guides mention. A counter closing at 5 PM does not always mean the building locks at 5 PM. Where a self service kiosk exists, stamps and postage can keep moving for hours after the clerk leaves.
What time does USPS open?
Most retail counters open between 8 AM and 9 AM, Monday through Friday. A small number open earlier, closer to 7:30 AM, usually in busier metro areas. Rural single window offices sometimes open a little later, closer to 9 AM.
Opening time is generally more consistent than closing time. Staffing a counter for the morning rush costs less than staying open late. Most offices cluster around the same one hour opening window as a result.
One exception exists. A branch that shares space with a larger retail or shipping operation can open earlier to match that host business. Those cases are rare enough to always check the locator first.
When does USPS close on Saturday?
Saturday hours are shorter almost everywhere. Most counters run from around 9 AM to somewhere between noon and 1 PM. A Saturday closing time past 2 PM is uncommon.
Rural and small town branches cut Saturday hours the most. A portion do not open on Saturday at all. That pattern is common enough to deserve its own breakdown, in Saturday retail hours.
Closing time is not the same as delivery cutoff
Two different clocks get confused constantly. The retail counter closing time is when a clerk stops serving customers. The carrier delivery cutoff is when your mail carrier finishes the route, and that can run much later.
USPS carriers can deliver up to 8 PM in many areas. That is well after most counters have shut for the day. Asking what time does USPS close is not the same question as asking when your mail will arrive.
If your real question is about the carrier, not the counter, the fuller answer sits in two other guides. See when your carrier actually finishes the route and how late a carrier can run during busy periods.
Holidays change the schedule completely
Every closing time above assumes a normal business day. On any of the 11 federal holidays USPS observes, the counter does not open at all. Posted weekday hours do not apply on those dates.
The full 2026 list, including a nuance on how Independence Day works this year, is in the complete USPS holiday calendar. For a deadline near a holiday weekend, check the date against the USPS holidays and events page directly.
Or skip the manual check entirely. Run the date through the holiday and delivery day checker for a fast yes or no answer.
Peak season hours can run later than usual
Regular hours are not fixed all year. In the weeks before Christmas, USPS often extends retail hours at high volume locations to handle the surge. Some of those branches add Saturday afternoon hours, and a select few even open briefly on Sunday.
Priority Mail Express can also move on Christmas Day itself in a limited number of markets, for an added fee, which is well outside the normal closed on holidays rule. None of this is guaranteed at any single branch. The safest move during peak season is the same one that works the rest of the year: check the locator for that specific date rather than assuming last month’s hours still apply.
What to do if you need postage after hours
A closed counter does not have to end your trip. Self service kiosks handle most common jobs. That includes postage printing, stamp sales, and package weighing, often around the clock at larger stations.
If a kiosk is not nearby, usps.com fills the gap. It covers ordering stamps, printing shipping labels, and scheduling a carrier pickup from home. A broader rundown of every stamp buying option, including retailers open later than the post office, sits in where to grab stamps after the counter closes.
The bottom line
Most USPS retail counters open around 8 AM to 9 AM. Most close around 5 PM to 5:30 PM on weekdays, with a shorter Saturday window and no set national time. Lobby and kiosk access often extends past the staffed hours.
For a specific branch on a specific day, the location locator beats any general rule, including this one. It is the only source that shows the exact minute your own branch locks up today.
