These figures show that UPS is performing better financially than USPS. However, such statistics don’t necessarily mean UPS provides all your shipping needs or that USPS is an unreliable courier.

How do UPS and USPS differ in their shipping services? What benefits and disadvantages does each courier have? Are there differences in the costs and delivery times of these services?

What Is the Difference Between UPS and USPS?

One of the main differences between USPS and UPS is that many USPS services ship up to 70 pounds (lbs) locally, while UPS can ship larger packages of up to 150lbs.

Another difference is that United Parcel Service has same-day delivery and competitive prices for large packages, partly due to having its own airline for air cargo.

Meanwhile, the United States Postal Service is the only last-mile delivery company that can reach every address in the United States.

Do UPS and USPS Work Together?

UPS has services called UPS SurePost and UPS Mail Innovations, allowing the company to work with USPS to deliver mail.

UPS SurePost is a service for non-urgent, low-value shipping needs. In this service, UPS picks up your package, and USPS makes the final delivery.

Meanwhile, Mail Innovations is an infrastructure that allows UPS to work with USPS to provide mail solutions with less prep time, consistent transit times, reliable delivery dates, and better postal rates.

What UPS Is Best for and Why

Suppose you’re looking for a major shipping industry player that specializes in speedy and secure delivery and has a comprehensive tracking system. In this case, consider UPS as one of the best choices.

Advantages of UPS for Business Shipping

Businesses can experience the following benefits when shipping with UPS:

  • Guaranteed express shipping: UPS Next Day Air provides guaranteed, time-definite next-day delivery.

If you have guaranteed delivery, you’ll likely be at ease knowing your parcel will arrive on time. This guarantee can also help keep customers happy and your business running smoothly.

  • A preferable choice for heavy shipments: As discussed earlier, USPS has a weight limit of 70lbs for most services, while UPS lets you ship up to 150lbs. Thus, you can consider choosing UPS for shipping heavier packages.
  • Comprehensive tracking services: UPS Tracking has several ways to track your package and helps you stay informed of your item’s current status, unexpected delays, and shipment delivery.

Disadvantages of UPS for Business Shipping

While UPS can be an excellent service in many ways, it isn’t perfect. Here are some areas you have to sacrifice if you ship with UPS:

  • More expensive services: Two main factors that increase UPS’ shipping costs are the fees and surcharges added to the base rates. These fees include fuel, demand, and remote area surcharges.
  • No free package pickup: UPS imposes a residential or area surcharge for pickups in residential areas.
  • No free Saturday delivery: UPS charges a $4 fee per package for Saturday ground commercial deliveries.

What USPS Is Best for and Why

USPS can be an excellent choice if you need to ship small, light packages for a relatively affordable price. You can also consider USPS if you send these small packages frequently.

Furthermore, USPS can be your go-to solution if you ship to residential mailboxes and P.O. boxes.

Advantages of USPS for Business Shipping

USPS can benefit business shipping in the following ways:

  • The cheapest option for small packages: USPS is a relatively inexpensive delivery service for companies that ship small items.
  • More reliable than in the past: USPS had a reputation for delaying shipments or misplacing packages. However, the Postal Service has significantly improved its on-time delivery rates and reliability recently.
  • Delivers to mailboxes and P.O. Boxes: The USPS has a monopoly on Post Office (P.O.) boxes and mailboxes. USPS is the only shipping service that does not need to drop off packages at customers’ doorsteps.

Disadvantages of USPS for Business Shipping

While USPS has the potential for many shipping needs, it still has several downsides, such as the following:

  • Tracking is unreliable: USPS may have improved its reliability over time, but packages still go missing occasionally. USPS’ tracking system is also unreliable as it does not help address lost or delayed package deliveries.
  • Poor customer service: Merchants often report that missing packages can be difficult to locate, and the assured refund can be a hassle to claim.

USPS vs. UPS: Which Is Better for Small Businesses?

To determine whether UPS or USPS is better for your small business, you should evaluate their customer satisfaction ratings and solutions for online stores.

According to the 2023 American Customer Satisfaction Index survey results, UPS scored 78, while USPS scored 71.

UPS vs. USPS Reliability: Which One Is Safer?

Comparing the reliability of UPS and USPS is challenging because they are two of the main carriers in the U.S.

UPS is one of the first companies to provide real-time tracking and offer highly predictable shipping services with a 97% rate of on-time deliveries.

Meanwhile, USPS also has a tracking service for each package. However, the USPS system is less reliable because it has different rules for scanning parcels.

USPS often doesn’t scan the package until it arrives at a depot. So if you’re checking your shipment’s tracking information, you can get confused about the item’s exact status.

Can You Drop Off a USPS Package at a UPS Store?

Previously, you could drop off your USPS package at a UPS Store because USPS drivers regularly made collections from these locations. However, USPS officially suspended this service at the beginning of 2020. From then on, you can no longer drop off USPS packages at these locations.

USPS, UPS, and FedEx: Which Is Best for Different Use Cases?

The following use cases show which courier you can consider using for a particular event:

  • Flat rate shipping: Consider USPS for flat rate shipping as this service is cheaper than UPS Simple Rate. As of June 2023, USPS’ price starts at $8.55 for a small flat-rate box, while UPS’ flat rate for extra small mail starts at $10.20.
  • Three-day delivery: If you’re shipping packages up to 150lbs within the U.S., choose UPS 3 Day Select for your three-day shipping needs. USPS also has a three-day service under Priority Mail but can only ship up to 70lbs.

Examples of Use Case Scenarios With Answers

The examples below demonstrate situations based on the use cases mentioned above.

Example 1

Suppose you want to send an item using the smallest-sized flat-rate packaging. Since USPS has lower flat-rate prices than UPS, according to the discussion earlier, you can choose USPS for shipping your item.

Example 2

If you want to send an item weighing 100lbs that must arrive in three days, consider UPS as your choice. With UPS 3 Day Select, you can send up to 150lbs of packages. Thus, this service can cover your package’s weight.

Which Is Cheaper: UPS, USPS, or FedEx?

Determining which courier is the cheapest can be challenging because multiple factors can influence shipping prices.

For example, one courier may provide the cheapest flat rate prices for a specific date or weight, while another courier may be more affordable for heavier packages.


Aside from cost and delivery time comparisons, customer reviews and ratings are other factors to consider when choosing which courier will send your package.

UPS Reviews

Trustpilot reviews show that UPS scored 1.2 stars out of 5 based on more than 28,600 reviews as of June 2023. Some issues raised were lost packages and failure to deliver parcels.

USPS Reviews

USPS’ Trustpilot reviews scored 1.2 stars out of 5, similar to UPS, but with only a little over 6,200 reviews. Significant issues raised include lost packages and poor customer service.

5 Ways to Cut Shipping Carrier Costs

Here are five valuable tips on lowering shipping costs, no matter which carrier you’re using.

Optimize Your Item’s Packaging Size (the Smaller, the Better)

Whichever carrier you choose, keeping your packaging as small as you can get can help keep your shipping costs down. If your packaging is too large for your items, the carrier can charge for your package’s dimensional weight (DIM) instead of the actual weight.

DIM is the space your package occupies in a carrier’s truck. Shipping companies usually bill you according to the actual weight or DIM weight, whichever costs higher.

Ask for Discounted Shipping Rates

Saving money on shipping involves taking advantage of economies of scale.

Economies of scale occur when production increases and causes costs to spread over many goods, leading to higher cost savings.

In other words, the more items you ship, the more leverage you have when negotiating discounted rates with the carriers.

Ship From Closer Shipping Zones

If you’re starting an e-commerce business, you may consider keeping your inventory on hand to fulfill your orders. However, doing so can present a challenge when you include distance in the equation.

Aside from how heavy and how big your package is, the total distance it must travel to reach its final destination counts.

Switch to Poly Mailers

Poly mailers weigh less and take up less space than boxes. Since weight and volume affect your shipment’s price, the reduced weight and volume poly mailers provide can help reduce costs.

Select Standard Shipping

Choosing a service with a slower shipping speed can help lower costs because it uses fewer resources. If you’re not in a hurry, consider standard shipping rather than the faster but more expensive services.

Is It Better to Use USPS or UPS?

Whichever courier you choose ultimately depends on your shipping needs and budget.

If you’re an e-commerce owner whose products are mainly items that don’t weigh over 70lbs, you may want to choose USPS. On the other hand, if your customer base is primarily outside the U.S., UPS may be a great choice for your international market.

USPS Shipping

USPS is the only delivery service that can reach every U.S. address comprising 160 million residences, businesses, and Post Office Boxes.

If you need to send small, lightweight packages like t-shirts, magazines, and coffee, consider USPS as your courier.

UPS Shipping

As of 2022, UPS had a global reach of more than 220 countries and delivered 24.3 million packages daily.

Choose UPS if you need to ship heavy packages like televisions, furniture, and anything between 70lbs and 150lbs.

Choosing a Shipping Company and Making Economic Decisions

Whether you’re in the e-commerce business or shipping products for personal reasons, finding the best prices and services to meet your shipping needs is essential.

In such cases, choosing a courier depends on which one best fits a specific situation. Thus, it’s not uncommon to have more than one courier. For example, one can handle smaller packages, and the other can ship larger ones.

There are also ways to lower your shipping costs, such as by using flat rate shipping. Depending on your recipient’s location and the package’s weight, flat rate shipping can be an economical choice.

A Few Words About UPS History

UPS started in 1907 when two enterprising teenagers opened a delivery service business named the American Messenger Company in a Seattle basement using a $100 loan. The company expanded to California in 1919 and renamed the business to United Parcel Service.

In 1985, UPS started its Next Day Air service. In 1988, the Federal Aviation Administration (FAA) approved the company’s plan to operate its own aircraft.

Still Not Sure?

If you’re still unsure what courier to pick for your needs, the following sections may help with your decisions.

How Large Is Your Package?

If you want to send a package below 70lbs, consider shipping with USPS, as this weight is the maximum allowed for most USPS services. For packages that go up to 150lbs, choose UPS.

Where Is Your Nearest Drop-Off Location?

USPS and UPS have numerous drop-off points in Los Angeles, Dallas, Miami, Chicago, Detroit, and other cities across the United States. Depending on your location, one may be more accessible or convenient for you than the other.

Do You Require a Pickup and Delivery Service?

USPS provides free package pickup from your office or home at a schedule that’s convenient for you.

If you prefer UPS instead, you can drop off your package for free at a UPS Access Point or UPS Store.

Which Shipping Carrier Option Is the Best for E-commerce?

Consider USPS’ business solutions if you’re seeking volume discounts for your e-commerce business. USPS has various shipping services, tools, and postage options like Click-N-Ship and Business Customer Gateway, providing cost-effective shipping methods.

If you need a solution for managing orders across large online platforms in one consolidated dashboard, you can choose UPS instead.

What Shipping Company Is the Best for International Packages?

The best shipping company for international packages depends greatly on your package’s size, destination, and how fast you need the package to arrive.

If you need to ship small packages that don’t require fast, time-sensitive shipping, consider USPS as your option. For larger packages that need fast delivery, UPS may be a viable choice.
