When people ask is ups and usps the same, the answer is no. UPS is a private package delivery business founded in 1907. The Postal Service is a federal agency that has been a permanent part of the federal government since 1792.
The confusion is easy to understand. The names differ by one letter, both deliver parcels, and one UPS service, Ground Saver, can end its trip in a mail carrier’s truck. This guide explains who runs each one, how they differ, and when they really do work together.
Holiday prices through January 17, 2027: USPS added a temporary price increase from October 4, 2026 to January 17, 2027 for Priority Mail Express, Priority Mail, USPS Ground Advantage and Parcel Select. During that window, retail Ground Advantage starts at $8.40, Priority Mail at $11.50 and Priority Mail Express at $37.05.
Priority Mail Flat Rate costs $13.90 for the envelope, $14.25 legal, $15.00 padded, $14.65 for the small box, $25.80 medium and $36.10 large ($34.65 APO/FPO/DPO). Priority Mail Express flat rate envelopes are $38.25, $38.55 legal and $39.25 padded. Prices in the rest of this article are the regular July 12, 2026 prices, which return January 18, 2027, and stamps, letters and Media Mail are not affected.
Is UPS and USPS the same company?
They are two separate organizations with different owners, different funding and different rules. The next sections cover each one, then the table compares them.
What UPS is
UPS began as a bicycle messenger service in 1907, started with a $100 loan. It now calls itself the world’s largest package delivery company, with about 460,000 employees, service in more than 200 countries and territories, and roughly 20.8 million packages a day. It earns its money by selling shipping to customers, and it is not part of the government.
UPS runs its own trucks, planes, hubs and drivers. Its domestic services are Ground, 3 Day Select, 2nd Day Air and the Next Day Air family, all for packages up to 150 lb and 108 in long. You can read the full ladder on the UPS domestic services page.
What USPS is
USPS describes itself in its annual Form 10-K as an independent establishment of the executive branch of the United States government. It generally receives no tax dollars for operating expenses and pays its way from the sale of postage, products and services. It also carries a universal service obligation, which means it must serve every area of the country.
That obligation shows in the numbers. USPS delivers to nearly 167 million residences, businesses and Post Office Boxes. A private company like UPS has no such obligation, so it prices and plans its network as a business.
Is UPS the post office?
No. A post office is a USPS retail location, and UPS does not run any.
UPS customers use The UPS Store, UPS Access Points and scheduled pickups instead. To see where a UPS package can be left, read how a UPS Access Point works.
People also search for “is ups united postal service” or “is ups the united states postal service.” The answer is no to both. UPS is a company name, United Parcel Service. USPS is the government body, the United States Postal Service.
Why people mix them up
Three things cause most of the mix ups. The initials look alike, both carriers move parcels, and some UPS packages now finish with a mail carrier. A package that arrives in a USPS truck with a UPS tracking number makes the question reasonable.
What is the difference between UPS and USPS?
The table below puts the main differences side by side. Every row reflects what each carrier says about itself.
| Question | UPS | USPS |
|---|---|---|
| Who runs it | Private company | Independent establishment of the executive branch |
| Founded | 1907 | 1792 (permanent federal service) |
| How it is funded | Sells shipping services | Postage and service revenue, generally no tax dollars for operations |
| Mailbox delivery | No | Yes |
| Letters and cards | Not its focus | Core service |
| Domestic parcel limit | 150 lb, 108 in long | Varies by service |
| Flat price boxes | Simple Rate, up to 50 lb, from $12.20 for the smallest box | Priority Mail Flat Rate, from $13.65 for the Small Flat Rate Box |
| Flat price limits | Simple Rate: 1 cubic foot maximum, domestic only | Flat Rate price covers whatever fits the box |
| Where you drop off | UPS locations and Access Points | Post Offices and collection boxes |
The flat price rows are not a clean match. UPS prices Simple Rate by volume, from 1 to 100 cubic inches up to 1,051 to 1,728 cubic inches. USPS prices Flat Rate by box shape.
UPS figures are “starting at” prices that can change, so confirm them on UPS before you ship. The USPS price comes from the July 12, 2026 price notice.
Does UPS and USPS work together?
Yes, in one specific service. UPS Ground Saver is a lower cost option for less urgent packages, and UPS calls it the updated name for the service formerly known as UPS SurePost. The UPS Ground Saver page states that packages are delivered by UPS and the USPS.
UPS moves the package through its own network, then hands it to the Postal Service for the final stretch.
Because USPS can finish the trip, Ground Saver reaches U.S. PO Boxes and APO, FPO and DPO addresses, which ordinary UPS Ground does not serve. The arrangement between the two carriers has been renegotiated more than once, and the history is in what UPS SurePost and Ground Saver are.
What this means for your package
You still have one UPS tracking number, and UPS shows tracking while the package is in its network. UPS also says the delivery photo is available only for packages UPS delivers, not those handed to USPS.
If the tracking stalls after a handoff, the USPS tracking guide covers the usual reasons. Deliveries run Monday through Saturday.
Ground Saver transit times are comparable to UPS Ground plus about one to two extra business days. It includes coverage up to $50 per package, subject to UPS terms. That makes it a budget service, not a fast one.
If speed matters, UPS sells faster options. Ground takes 1 to 5 business days, with 85% delivered in 3 days or less. UPS also lists same day delivery through Roadie, with 2 hour, 4 hour and end of day windows.
How the flat price options compare
UPS Simple Rate comes in five box sizes by volume. Prices start at $12.20 for the extra small box, $15.80 for small, $18.95 for medium, $24.85 for large and $30.95 for extra large. It needs no account or contract, covers 50 states, and is not available for international shipments.
USPS Priority Mail Flat Rate boxes cost $13.65 for the Small Flat Rate Box, $24.80 for the Medium Flat Rate Boxes and $34.00 for the Large Flat Rate Box. The price stays the same whatever the box weighs or wherever it goes in the U.S., as long as it closes. UPS Simple Rate also has a 50 lb cap and offers $100 of declared value coverage.
UPS charges standard rates by dimensional weight and zone for anything over the Simple Rate limits. That is the point where comparing both carriers pays off.
Can I drop off a UPS package at the post office?
No, not as a normal UPS shipment. A Post Office accepts USPS mail and parcels, not UPS labels. A UPS package goes to a UPS location, a UPS Access Point or a scheduled pickup.
Ground Saver changes how the package travels, not where you drop it. You hand it to UPS, and UPS decides whether USPS finishes the delivery. You do not choose that.
The reverse is also true. A USPS label cannot go to a UPS location. Each carrier takes only its own shipments, so buy the label from the carrier you plan to use.
Which one should you use?
The best choice depends on the package, not the brand. Is ups and usps the same price for your box? Almost never, so use these rules as a starting point.
- Choose USPS for light parcels, anything going to a PO Box, and shipments where free Priority Mail boxes help. See every free Priority Mail box size before you buy packaging.
- Choose UPS for heavy or oversize parcels, up to 150 lb and 108 in long, and for the guaranteed Next Day Air services.
- Choose either carrier for a mid size box and compare the quote. Weight, size and distance change the winner from one package to the next.
- Choose UPS when you need Saturday delivery on a faster service. UPS offers it on 3 Day Select, 2nd Day Air and the Next Day Air and Next Day Air Early services.
On guarantees, UPS says its Service Guarantee currently covers domestic Next Day Air Early, Next Day Air, Next Day Air Saver and 2nd Day Air A.M. only. It stays suspended for all other UPS services, so plain Ground and 2nd Day Air are not guaranteed.
Coverage for a lost or damaged item is a separate question. For a valuable item, check what USPS Priority Mail insurance covers and compare it with the UPS declared value terms.
Is UPS cheaper than USPS?
Sometimes, and sometimes not. A one pound parcel, a box going across the country and a heavy package can each favor a different carrier. The shipping cost comparison tool prices the same box on both.
For USPS rates by weight and flat rate size, see current Priority Mail rates.
If delivery date matters more than price, try the delivery time estimator before you pick a service.
The bottom line
The answer to is UPS and USPS the same is no: one is a private company, the other a federal agency. They share a handoff on Ground Saver and little else. Compare a real quote on both before you ship, because the cheaper carrier changes with the box.
