Key Answer Up Front
No, Amazon has not stopped using the U.S. Postal Service (USPS). The companies continue to work together on certain domestic routes and delivery segments, especially in less densely populated areas where USPS performs transportation and last‑mile delivery. USPS remains a key carrier for Amazon’s inbound logistics and some end‑of‑day deliveries in specific regions. Amazon’s network relies more heavily on its own carrier, Amazon Logistics, and partnerships with regional and national carriers like UPS and FedEx, but USPS remains one component of the broader mix.
Amazon and USPS: The Relationship Today
Amazon and USPS operate as complementary partners in specific lanes rather than in direct competition across all geographies. USPS handles final delivery on many rural and lower‑density routes, leveraging its universal service obligations and deep coverage. In parallel, Amazon has built out Amazon Logistics, relying on owned drivers, station‑based operations, and a broader carrier network that includes UPS and FedEx. For businesses, this means orders may ship via multiple carriers depending on origin, destination, service level, and capacity availability.
How Volume Flows Between the Carriers
Shipments between Amazon and USPS typically move in two directions:
- Inbound: USPS can accept parcels from sellers or returns destined for Amazon facilities, feeding into Amazon’s sorting network.
- Outbound: Amazon may use USPS to complete final delivery, particularly in areas where USPS provides more consistent coverage or better economics.
Both carriers adjust routing and scope based on pricing, service requirements, and operational constraints, so the exact mix varies by lane and over time.
Historical Context and Contractual Background
The relationship between Amazon and USPS has evolved since the early 2010s as Amazon’s volume grew and USPS sought to leverage its network for higher‑value deliveries. USPS offers competitive last‑mile rates and operates under a federal mandate to serve all addresses, making it an attractive option for certain routes. Amazon, meanwhile, has invested heavily in its own logistics capacity while also using other major carriers. Though specific contract terms are not public, the arrangement reflects standard commercial partnerships in the logistics sector rather than a dependency or a full replacement of one carrier by another.
Key Milestones and Events in the Relationship
| Date or Period | Event | Why It Matters |
|---|---|---|
| Early 2010s | Amazon begins increased use of USPS for last‑mile delivery in rural areas. | Expands coverage while controlling costs. |
| 2013 | USPS and Amazon negotiate favorable delivery contracts; volumes rise. | Strengthens USPS economics and reliability. |
| 2019 | Media reports suggest reduced USPS usage as Amazon expands own fleet. | Signals shift toward owned capacity and more diversified carrier mix. |
| 2020–2023 | Continued use of USPS for specific lanes, with increased Amazon Logistics capacity. | Balances scale, cost, and service reliability. |
Operational Realities That Shape Carrier Use
Carrier selection depends on cost, speed, coverage, and capacity. USPS excels in universal coverage and price‑sensitive routes, while Amazon Logistics offers greater control, service consistency, and integration with seller systems. In dense metro areas, Amazon may rely more on its own fleet and UPS/FedEx; in remote or lower‑density areas, USPS remains an important option. Seasonal peaks and network constraints can also shift the balance between carriers.
Factors Influencing Which Carrier Handles a Shipment
- Delivery address density and route economics.
- Service level selected (e.g., speed vs. cost).
- Carrier capacity and network conditions at dispatch.
- Contractual agreements and commercial negotiations between Amazon and USPS.
What This Means for Sellers and Customers
For sellers, understanding that multiple carriers can fulfill orders helps set accurate expectations around transit times and tracking visibility. Orders may ship via USPS, Amazon Logistics, UPS, or FedEx depending on the scenario, and all are valid service paths within Amazon’s broader network. For customers, this means delivery experience can vary by location, with USPS often providing reliable final delivery in areas where Amazon’s own network is less dense. Tracking information will indicate the actual carrier for each package.
How to Check Which Carrier Is Handling Your Shipment
The simplest way to confirm whether USPS, Amazon Logistics, or another carrier is moving your package is to review the shipping confirmation or tracking details in your order. The ‘Track Package’ page or email includes the carrier name and tracking number, which you can use to follow the latest status. If you’re a seller, your Amazon Seller Central shipping reports will show which carrier was selected at dispatch.
Bottom Line
Amazon has not stopped using USPS, and USPS continues to play a role in Amazon’s logistics ecosystem for specific routes and delivery types. The partnership is part of a broader strategy that blends owned infrastructure, regional carriers, and national networks to balance cost, coverage, and reliability. Expect this collaboration to continue, with usage varying by geography, seasonality, and service requirements.
