USPS vs UPS
Not sure which shipping service to use? There are several factors to consider, depending on your business needs.
Let’s start with cost since it’s usually the reason we choose a shipping service.
Cost: Is UPS or USPS Cheaper?
USPS costs less than UPS for shipments up to 12 ounces (oz). But UPS competes with its Ground Saver option (UPS SurePost).
UPS Ground Saver vs USPS Ground Advantage (UPS SurePost) Speed and Cost
UPS Ground Saver Delivery Speed: 5-7 business days
USPS Ground Advantage Delivery Speed: 5 days
Here are some common rates as of September 2023 going from East Coast (17313) to West Coast (90210) using ShipStation (rates should be similar with other shipping software such as EasyShip or Pirate Ship):
| Dimensions | Weight | USPS Ground Advantage | UPS Ground Saver |
| 4x4x4″ | up to 4 oz | 4.13 | 6.35 |
| 4x4x4″ | 8 oz | 4.44 | 6.35 |
| 4x4x4″ | 12 oz | 5.33 | 6.35 |
| 4x4x4″ | 14 oz | 6.78 | 6.35 |
| 6x4x4″ | 1 lb | 8.03 | 6.35 |
| 8x8x8″ | 3 lb | 10.97 | 10.98 |
| 12x8x8″ | 7 lb | 13.15 | 13.14 |
| 16x12x12″ | 20 lb | 23.11 | 22.6 |
Prices in bold are cheaper. Rate differences are negligible for much over 1 lb.
Warning about UPS surcharges
The rates above may spike with UPS for various reasons. UPS Ground Saver rates increase 3x to 5x if not within the contiguous United States. Rural or remote addresses may see additional surcharges. Unlike UPS, USPS charges an equitable rate no matter how inaccessible the address.
Use USPS Ground Advantage for packages up to 12 oz and UPS Ground Saver for packages from 12 oz to 3 lbs if you’re not concerned about UPS pickups, slower delivery speed, or surcharges. Price differences are negligible over 3 lbs (assuming there are no UPS surcharges). If faster delivery speed is crucial, then stick with USPS Ground Advantage.
Pickup Service
USPS provides free pickups, unlike UPS. If you’re a small business with under 50 packages daily, it’s more time and cost effective to use USPS.
Customer Returns with USPS and UPS
If a customer changes their mind after shipment
USPS = Just RTS and in the Mailbox
Have the customer write ‘RTS’ on the package and leave it in their mailbox as long as the package is unopened. This return method is free but does not provide tracking. For tracked returns, or for opened packages, provide a new label for the customer.
UPS = Buy another Label and More
You or the customer must purchase a return label and schedule a pickup unless the customer is willing to go to their local UPS location.
Returns for opened packages
Customers can place USPS returns in their mailbox for pickup or take them to the post office. But there’s the extra step of creating and emailing a return label, unless your order platform does this for you. UPS offers a streamlined returns process that includes a pre-printed label with each shipment.
Reliability Comparison
Reliability is negligible between USPS and UPS Ground Saver (SurePost) as this UPS service uses USPS for last mile delivery. We’ll cover the reliability of each carrier’s overall shipping services.
UPS Reliability
UPS is known for its global logistics network, efficiency, tracking abilities, and on-time delivery rates. The company invests heavily in technology and infrastructure to optimize its operations. Customers, especially businesses, often choose UPS for its predictability. Its commitment to tracking accuracy is unmatched by USPS.
Is USPS Reliable
USPS Mail carriers may have difficulty delivering packages to unusual addresses like gated communities or new housing developments where the address information hasn’t been updated in their system. Also, during holidays, there can be substantial delays. Even during the normal season, staff shortages often arise that force carriers to cover additional routes, resulting in skipped deliveries. USPS tracking information is sometimes inaccurate. For example, packages may show delivered when they aren’t actually delivered until the following business day.
Reliability Conclusion
During severe weather or a pending carrier strike, USPS is the safer bet as they deliver rain or shine. Otherwise, the difference is negligible or depends on the address.

Customer Service for USPS and UPS
UPS Customer Service
UPS has several support options. Their phone support is usually the best bet.
USPS Customer Service
Going to your local post office is best. Speaking to a live person using the public USPS support phone number is difficult or sometimes impossible.
Which Should You Choose?
This depends on your margins and your risk tolerance for losing packages and having to reship. If most of your products are light and cost under $20 per unit to produce, then saving $1 to $2 per shipment is huge. In this case, go with USPS and bolster reliability with late shipment alerts from ShipAware.
Increase USPS Reliability and Keep the Lower Cost
You can have the best of both worlds for packages up to 12 oz. Increase reliability and keep the lower cost of USPS by using a shipping notification service like ShipAware to send alerts when shipments are running behind your promised delivery schedule.

Which is Best for International Shipping?
GlobalPost is the cheapest for lighter packages in our experience.
However, if you have to choose between USPS and UPS for international shipping, then use UPS as it usually has a better speed to cost ratio. Remember to include an invoice that shows item prices, especially for UPS international shipments, or UPS may hold the package in customs.
