Because it delivers mail and packages to homes and businesses nationwide, the United States Postal Service (USPS) is an essential part of our everyday lives. “When does USPS deliver to my zip code by zip code?” is among the most common inquiries. Understanding USPS delivery times by zip code can help you save time and lessen frustration, whether you’re anticipating a package or trying to schedule your day around mail delivery.
There are a number of variables that affect when your mail arrives, even though the USPS does not provide an exact delivery time for every zip code. We’ll examine typical delivery windows, explain when does USPS deliver to my zip code by zip code, and break down how USPS delivery times operate in this post.
USPS Delivery Times: General Overview
When does USPS deliver to my zip code by zip code? Before diving into zip-code-specific information, it’s helpful to understand how USPS schedules its deliveries.
Typical Delivery Window
Typically, USPS delivers Monday through Saturday between:
- For residential addresses, 9:00 AM to 5:00 PM
- Business hours are 8:00 AM to 5:00 PM.
Delivery may occasionally take place as late as 6:00 or 7:00 PM, particularly during periods of high mail volume or inclement weather.
Factors That Affect Delivery Times
Your mail delivery time may change based on:
- Mail volume: may rise during tax seasons, sales occasions, or holidays.
- Location: In urban areas, delivery times might be shorter than in rural ones.
- Route scheduling: Depending on delivery priority and efficiency, carriers adhere to predetermined routes.
- Road conditions and weather
- Service type (Priority Mail, First-Class, etc.)
How to Check USPS Delivery Time by Zip Code
When does USPS deliver to my zip code by zip code? You can estimate your delivery window using a number of tools and techniques, even though USPS does not publicly disclose precise delivery times by zip code.
1. USPS Informed Delivery
Informed Delivery, a free USPS service, provides digital mail previews and package tracking.
Benefits:
- View the mail that arrives every day.
- Receive alerts and estimated delivery times.
- Monitor packages in real time.
Once you sign up, you’ll get an idea of your daily delivery pattern. After a week or two, you’ll notice what time mail typically arrives at your address.
2. Track Packages with ZIP Code Accuracy
If you’re expecting a package, enter your tracking number at USPS.com or use the USPS mobile app. While it won’t tell you the exact hour of arrival, it will indicate if it’s out for delivery, meaning it’s on the truck and should arrive that day—often within the standard 9 AM–5 PM window.
3. Contact Your Local Post Office
Your local post office knows your delivery route and schedule. They may be able to tell you what time the carrier usually delivers in your zip code. You can find your local post office contact details at the USPS Locator Tool.
Delivery Time Examples by Popular Zip Codes
Below are some general delivery time windows based on user-reported data. Please note, times may vary based on season, route changes, and volume.

How to Optimize USPS Deliveries in Your Area
Here are a few ways to improve or better manage your USPS mail deliveries:
1. Use Hold Mail or Change of Address Services
Going on vacation or moving? Set up a Hold Mail request or a Change of Address via USPS to ensure your mail is handled properly.
2. Install a Secure Mailbox
If you’re receiving packages regularly, consider a secure or locking mailbox to prevent theft, especially if your delivery occurs late in the day.
3. Sign Up for Text or Email Alerts
Use your tracking number to set alerts for when your packages are scanned at different delivery stages, including “Out for Delivery” and “Delivered.”
Delivery Time Exceptions
There are exceptions to USPS’s typical delivery schedule:
- Holidays: USPS does not deliver on federal holidays like Christmas, Thanksgiving, and New Year’s Day.
- Sundays: Only Priority Mail Express and some Amazon deliveries are made on Sundays.
- Severe weather: Snowstorms, hurricanes, or wildfires can delay mail delivery.
- National emergencies: Events like the COVID-19 pandemic temporarily disrupted normal operations in some areas.
