Does USPS Ground Advantage Deliver on Saturday?

Yes. USPS Ground Advantage delivers on Saturdays with no additional fees or surcharges. USPS treats Saturday as a standard delivery day across most of its services, and Ground Advantage is no exception.

This means that if your USPS Ground Advantage package is in transit and scheduled to arrive on a Saturday, it will be delivered during normal Saturday delivery hours, typically between 9 a.m. and 5 p.m., though deliveries can extend later during peak seasons.

For ecommerce brands, this has a practical implication: orders shipped mid-week via USPS Ground Advantage can arrive as early as Saturday, effectively giving customers a six-day delivery window (Monday through Saturday) rather than a five-day window.

Does USPS Ground Advantage Deliver on Sunday?

No. USPS Ground Advantage does not deliver on Sundays. If a Ground Advantage package would otherwise arrive on a Sunday, it will be delivered on the following Monday instead.

Sunday delivery through USPS is limited to two specific channels:

• Priority Mail Express: USPS's fastest shipping option, which includes overnight or two-day guaranteed delivery. Priority Mail Express delivers on Sundays with an additional surcharge of approximately $12.50.

• Amazon packages: USPS partners with Amazon to handle last-mile delivery for certain packages on Sundays in select locations. This is an Amazon-specific arrangement and does not apply to general USPS shipments.

For businesses that need Sunday delivery, Priority Mail Express is the only standard USPS option available. For a detailed breakdown, see USPS overnight shipping options.

USPS Ground Advantage Weekend Delivery: Saturday vs Sunday

What Time Does USPS Ground Advantage Deliver on Saturday?

USPS Ground Advantage follows the same delivery schedule on Saturdays as on weekdays. Postal carriers typically begin their routes around 9 a.m. and continue through the afternoon. Most packages arrive by 2 p.m. on Saturdays, though deliveries can extend to 5 p.m. or later during busy periods such as the holiday season.

Unlike Priority Mail Express (which offers guaranteed delivery by 10:30 a.m. in many metro areas), Ground Advantage does not have a guaranteed Saturday delivery window. The exact timing depends on your local post office's route schedule and package volume.

Does Saturday Count as a Business Day for USPS Ground Advantage?

Yes. USPS considers Saturday a regular business day for delivery purposes. This means that the "2–5 business days" delivery estimate for USPS Ground Advantage includes Saturdays.

For example, if a USPS Ground Advantage package is shipped on a Wednesday and has a 3-business-day delivery estimate, the delivery could arrive on Saturday (Wednesday → Thursday → Friday → Saturday).

Sundays and federal holidays are not counted as business days. A package that would otherwise arrive on a Sunday will be delivered on Monday.

How Does USPS Ground Advantage Weekend Delivery Affect Ecommerce Shipping Strategy?

For ecommerce brands, Saturday delivery through USPS Ground Advantage expands the effective delivery window without additional cost. Here is how it affects key post-purchase touchpoints:

• Delivery date accuracy. When calculating estimated delivery dates at checkout, Saturday should be included as a valid delivery day for Ground Advantage shipments. Excluding Saturdays from EDD calculations understates delivery speed and may cause customers to choose a more expensive shipping option unnecessarily.

• Proactive tracking. Customers expecting Saturday delivery need real-time shipment tracking updates through the weekend. A branded tracking page that reflects Saturday delivery status keeps customers informed without generating WISMO support tickets over the weekend.

• Shipping notifications. Automated notifications should trigger on Saturdays just as they do on weekdays. For example, "out for delivery" and "delivered" alerts should fire in real time, including weekends.

• Carrier selection. For brands using carrier allocation, Saturday delivery capability should be factored into routing decisions. USPS Ground Advantage's six-day delivery window (Monday–Saturday) can outperform competitors that only deliver Monday–Friday for certain routes.

• Exception management. Failed Saturday delivery attempts need the same NDR management workflows as weekday failures, i.e., automated rescheduling, address correction, and customer notification.
