Introduction to USPS Operating Hours
Understanding USPS hour is essential for anyone needing to mail packages, buy stamps, or access postal services. The United States Postal Service operates on a standard schedule but adjusts hours for weekends, holidays, and special occasions. Most post offices are open Monday to Friday from 9:00 AM to 5:00 PM, with limited hours on Saturdays. However, hours can vary by location, making it crucial to verify your local branch’s schedule. This guide covers USP hours for weekdays, weekends, holidays, and how to find real-time updates for your nearest post office.
Standard USP Hours: Weekdays and Saturdays
Most USP locations follow a Monday to Friday schedule, typically opening at 8:00 AM or 9:00 AM and closing by 5:00 PM or 6:00 PM. On Saturdays, many branches operate with reduced hours, often from 9:00 AM to 1:00 PM, though some may stay open until 3:00 PM.

If you need to send urgent mail, arriving early on Saturdays is recommended to avoid last-minute closures.
