Most post offices are open on Saturday, but with shorter hours than during the week. A common Saturday window is 9:00 AM to noon or 1:00 PM, though some branches open as early as 8:00 AM and a few stay until mid-afternoon. Smaller and rural offices sometimes close entirely on Saturdays. Mail delivery, however, runs as usual: your carrier still comes on Saturday even if the counter near you is dark.
Typical Saturday Hours
Saturday retail hours generally start between 8:00 and 10:00 AM and end by early afternoon. A frequent schedule is 9:00 AM to 12:00 PM, with some larger offices staying open until 2:00 or 3:00 PM. Smaller branches may run 8:00 AM to noon.1USPS. GOFFSTOWN Post Office Weekday hours at the same branch often run 8:00 AM to 5:00 PM or later, so Saturday is typically a half day at best.
Main post offices in cities tend to keep the longest Saturday windows. Contract postal units inside grocery stores or shipping centers follow the host business’s schedule, which can mean later hours than a standalone branch.
What You Can Do at the Counter
When the retail counter is open on Saturday, you can handle the same business you would midweek. That includes mailing letters and packages, buying stamps, sending money orders, and picking up items held for you. If a package didn’t fit in your mailbox or required a signature, Saturday counter hours are when you retrieve it.
Passport service is the exception to check on ahead of time. Not every post office is a passport acceptance facility, and among those that are, Saturday availability differs by location. Some facilities do accept passport applications on Saturdays by appointment.2Passport: DetailsForm. BERKELEY MAIN POST OFFICE Passport Acceptance Details If you need passport service on a weekend, search the State Department’s acceptance facility database or book through USPS rather than walking in.
Lobby Access After the Counter Closes
Many post offices keep an outer lobby unlocked well beyond retail hours, and most P.O. box locations allow 24/7 box access, though this varies by branch.3USPS. PO Boxes If the counter closes at noon on Saturday, you can still pull mail from your box that afternoon or evening.
Self-service kiosks in those lobbies let you buy stamps, weigh packages, and print Priority Mail and Priority Mail Express labels without a clerk.4USPS. Find USPS Post Offices and Locations Near Me When the Saturday retail window has already closed, the kiosk is a useful fallback.
The limitation: packages too large for a P.O. box and items requiring a signature still need a counter visit during retail hours.
Saturday Delivery
Saturday is a standard delivery day. Your carrier delivers First-Class Mail, USPS Ground Advantage, Priority Mail, and Priority Mail Express on Saturdays at no extra charge, and customers receive delivery six and sometimes seven days per week.5USPS.

One change worth knowing about took effect in April 2025. USPS now excludes Sundays and holidays from delivery-time calculations for items entered on a Saturday or the day before a holiday. In practice, a package you drop off Saturday afternoon won’t start its delivery clock until Monday. If timing is tight, mailing on Friday can effectively buy you a day.

When a Federal Holiday Cancels Saturday
Post offices close and mail delivery stops on federal holidays. When a holiday lands on a Saturday, the office is closed that day, and the preceding Friday may be treated as a holiday for USPS employees.10USPS About.

How to Check Your Local Branch
Because Saturday schedules vary so much, confirming before you drive over saves a wasted trip. The USPS location finder at tools.usps.com/locations lets you search by ZIP code or city and see each branch’s Saturday hours, available services, and lobby access times.4USPS. Find USPS Post Offices and Locations Near Me The USPS mobile app runs the same lookup, and you can call 1-800-ASK-USPS (1-800-275-8777) for hours at a specific branch. Holiday weeks are worth double-checking, since some offices adjust Saturday hours around long weekends even when the holiday itself falls on a different day.
