For many customers, the post office opens between 8:00 and 9:00 a.m. on weekdays and closes between 4:00 and 6:00 p.m. However, there is no single schedule for every United States Postal Service location. Hours depend on the branch, its staffing, and the services available there.
A small neighborhood station may have a shorter retail window than a large city branch. Some locations also keep the lobby, package lockers, or PO box area accessible after the customer service counter has closed. Checking the exact branch before leaving home is the safest way to avoid a wasted trip.
Most post offices operate Monday through Friday, but their opening and closing times can differ considerably. A busy main branch may open at 8:00 a.m. and remain open until 6:00 p.m., while a smaller office may operate from 9:00 a.m. to 4:30 p.m.
The USPS location finder provides the most reliable information for a specific address. Search by city, state, or ZIP Code, then review the listed retail hours, lobby hours, passport appointment availability, and any notices about temporary changes.
A common weekday schedule starts at 8:30 or 9:00 a.m. and ends around 5:00 p.m. Some branches open earlier for customers who need to mail packages before work, while others close earlier in rural or low-volume areas.
The final transaction may need to begin before the posted closing time. Customers mailing an international parcel, buying money orders, applying for a passport, or handling a complex shipment should arrive early enough for an employee to complete the service.
Retail counter hours apply to services that require an employee, including purchasing postage, mailing packages, sending certified mail, and collecting certain held items. These hours are often shorter than the building’s general access hours.
A lobby may remain open for PO box customers, self-service kiosks, or drop-off slots outside the counter schedule. Access is not guaranteed at every branch, so customers should confirm whether a location offers after-hours entry.

| Service or Need | Common Weekday Availability | Important Detail |
|---|---|---|
| Retail counter | About 8:00 or 9:00 a.m. to 4:30–6:00 p.m. | Exact times vary by branch |
| PO box access | May extend beyond counter hours | Requires the appropriate key or access code |
| Self-service kiosk | Often available during lobby hours | Services and payment options can differ |
| Package drop-off | During lobby access or counter hours | Check size, postage, and acceptance rules |
| Passport services | By appointment at selected offices | Appointment times may be limited |
Post offices generally close on federal holidays, including major holidays such as Thanksgiving and Christmas Day. Some holiday eves and other special dates may have reduced retail hours. Mail collection times can also change, even when the lobby remains open.
Weather, building repairs, staffing shortages, and local events can cause unexpected closures or altered hours. The USPS website may display a service alert, but a quick phone call to the branch can be useful when the visit is urgent.
If the retail window has closed, you may still be able to place a stamped letter in an indoor or outdoor collection box. Review the collection time printed on the box because an item deposited after the final pickup may not move until the next business day.
Self-service kiosks can handle some postage purchases and address-related tasks, but they do not replace every counter service. A kiosk may not accept an oversized parcel, verify identity, process a passport application, or provide advice about a complicated mailing.
A tracking number is the easiest way to monitor a package, but it is not the only information that can help. The sender, recipient address, mailing date, service type, receipt, and payment record may assist USPS staff when investigating a shipment. For additional guidance, see how to track a package when the tracking number is unavailable.
Customers picking up a held parcel should bring government-issued identification and any pickup notice when applicable. If another person is collecting the item, authorization and identification requirements may apply. Calling ahead can clarify what documents the branch expects.
The following steps can make a post office visit faster and reduce the chance of arriving after the service window:
It is also useful to prepare customs information for international shipments and verify that the package is sealed according to postal requirements. For returns, keep the merchant’s label and any receipt until the carrier accepts the parcel.
When you need a precise answer to “What time does the post office open and close on weekdays?”, use the USPS location finder for the branch you plan to visit, then check the listed retail and lobby hours separately. Confirm the schedule before you go, arrive early for specialized services, and keep your mailing receipt until the item reaches its destination.
