what time does usps deliver on saturday depends on the type of service selected for shipping. USPS typically delivers mail and packages on Saturdays between 9:00 AM and 5:00 PM. However, delivery times may vary depending on the specific location and the volume of mail being processed. For example, Priority Mail and First-Class Mail packages are usually delivered within these hours, but the exact time can fluctuate. USPS offers a variety of services for Saturday delivery, including Priority Mail Express, which guarantees next-day delivery even on weekends. It’s important to note that while Saturday is a regular delivery day for most USPS services, some locations may not offer mail delivery on weekends for certain types of mail, especially for less urgent services or in more remote areas. For the most accurate delivery time, it’s best to track your package through the USPS tracking tool or contact your local post office for more details.
