They are, and the statute leaves no room to argue about it. Congress established the Postal Service as an independent establishment of the executive branch and put its workforce in the postal career service, which the same title of the U.S. Code calls a part of the civil service. The label reads like paperwork until a holiday, a shutdown or a missing parcel turns it into something you can feel. The statute text and the USPS pages quoted beside it both date from a 2026-07-29 reading.
Postage revenue pays the carrier who walks your parcel up the driveway. That single fact explains most of what follows.
39 U.S.C. 201 is one line long: “There is established, as an independent establishment of the executive branch of the Government of the United States, the United States Postal Service.” Two chapters later, 39 U.S.C. 1001(b) settles the employment question: postal workers “shall be in the postal career service, which shall be a part of the civil service. Such appointments and promotions shall be in accordance with the procedures established by the Postal Service.” Both were read from the U.S. Code on 2026-07-29.
Read the second sentence twice and the nuance appears. Postal workers are inside the civil service, but the Postal Service writes its own hiring and promotion procedures rather than running applicants through the competitive-service machinery that fills most agency jobs. The same title provides separately for collective-bargaining agreements between the Postal Service and the bargaining representatives it recognizes, and requires each agreement to run for at least two years, per 39 U.S.C. 1206 read 2026-07-29. That is why a letter carrier and a park ranger can both be federal employees and still describe completely different hiring experiences.
| The question | What applies to a postal worker | Where it is written |
|---|---|---|
| Who is the employer | An independent establishment of the executive branch of the U.S. government | 39 U.S.C. 201 |
| Civil service or not | The postal career service, which the statute calls a part of the civil service | 39 U.S.C. 1001(b) |
| Who writes the hiring rules | The Postal Service itself, through its own appointment and promotion procedures | 39 U.S.C. 1001(b) |
| Retirement | Chapters 83 and 84 of title 5, the same systems the rest of the federal workforce sits in | 39 U.S.C. 1005 |
| Health coverage | “The Postal Service participates in the Federal Employees Health Benefits (FEHB) Program” | about.usps.com careers |
| Savings plan | The Thrift Savings Plan, with “automatic and matching contributions (up to 5 percent of pay) from the Postal Service” | about.usps.com careers |
| Hurt on the round | Subchapter I of chapter 81 of title 5, the federal work-injury scheme | 39 U.S.C. 1005 |
| Veterans preference | Applies “in the same manner and under the same conditions as if the applicant, officer, or employee were subject to the competitive service” | 39 U.S.C. 1005 |

The bottom row is the one that surprises people. On its own profile page, read 2026-07-29, the Postal Service writes that it “generally receives no tax dollars for operating expenses and relies on the sale of postage, products and services to fund its operations.” Federal employer, commercial revenue. Everything below follows from that pairing.
When the Postal Service observes a holiday it closes completely rather than running a reduced day. The notice for this year's Independence Day, published on about.usps.com and read 2026-07-29, says “All Post Office locations will be closed” and that “Regular mail delivery and retail services will resume on Monday, July 6.” UPS and FedEx publish their own calendars separately, which we track on the UPS and FedEx pages.
Because the money is postage rather than appropriations, a lapse in federal funding leaves the network running. The Postal Service put it in a statement dated Sept. 25, 2025, read 2026-07-29: “U.S. Postal Service operations will not be interrupted in the event of a government shutdown, and all Post Offices will remain open for business as usual.”
18 U.S.C. 1708 reaches anyone who steals mail matter from an authorized depository, or receives it knowing it was stolen, and sets the penalty at a fine “or imprisoned not more than five years, or both.” Read 2026-07-29. The statute is written around mail, so a parcel that never entered the postal stream is a different matter with a different set of people to call.
None of this makes the postal option automatically better. It makes the postal option behave differently on specific days and in specific emergencies, which is worth knowing before you choose a service for something that has to arrive on a date.
Since the payroll comes out of postage, it is worth seeing the postage. Two parcels went from Berkeley Heights, NJ to Kansas City, MO through our checkout on 2026-07-29, and every row that came back is printed here, postal and private side by side.
| Carrier and service | Price | Carrier counter price | Window returned |
|---|---|---|---|
| USPS Ground Advantage | $10.09 | $11.35 | 4-5 business days |
| UPS Ground | $11.52 | not returned | 5-6 business days |
| UPS 3 Day Select | $15.49 | not returned | 5-6 business days |
| USPS Priority Mail | $15.81 | $14.50 | 4-5 business days |
| UPS 2nd Day Air | $16.16 | not returned | 4-5 business days |
At one pound the postal row was both the cheapest thing on the board and tied for the shortest window, which is the ordinary result for light parcels. The Priority Mail line runs the other way: the post office counter came back below our checkout on this lane, so anyone set on that specific service is better off walking in. We would rather print that than hide it behind a column we left out.
| Carrier and service | Price | Carrier counter price | Window returned |
|---|---|---|---|
| FedEx Ground Economy | $17.60 | $21.57 | 5-6 business days |
| USPS Ground Advantage | $19.08 | $24.10 | 4-5 business days |
| UPS Ground Saver | $19.08 | not returned | 5 days estimated, no window |
| UPS Ground | $21.03 | not returned | 5-6 business days |
| FedEx Ground | $26.29 | $26.23 | 5-6 business days |
Eight pounds rearranges the board. The postal row lost the price contest by about a dollar and a half and won the speed contest by a day, and the widest counter-to-checkout gap on the page sits on that same postal line. Federal employment status is nowhere in this arithmetic; the box, the scale, the distance and the service are the whole of it.
Statutes get amended and postal pages get rewritten. Every source above is quoted at the date shown, so look at the live text before leaning on any of it for something that matters.
Yes. Title 39 of the U.S. Code establishes the Postal Service as an independent establishment of the executive branch, and places its workforce in the postal career service, which the same statute calls a part of the civil service.
The retirement chapters of title 5 are applied to them by statute, and the Postal Service says on its careers pages that it participates in the Federal Employees Health Benefits Program and pays automatic and matching contributions of up to 5 percent of pay into the Thrift Savings Plan.
No. Its own profile page states that the Postal Service generally receives no tax dollars for operating expenses and relies on the sale of postage, products and services to fund its operations.
No. A Postal Service statement dated Sept. 25, 2025 says operations will not be interrupted in the event of a government shutdown and that all Post Offices will remain open for business as usual.
It does not set the price at all. The box, the weight, the route and the service do. On the lane quoted here on 2026-07-29 the postal row was cheapest at 1 lb and second cheapest at 8 lb.
