Amazon (NASDAQ: AMZN) handled 6.7 billion parcels last year, up 9.8% year over year, compared to an 8.3% decline for the U.S. Postal Service to 6.6 billion pieces. UPS (NYSE: UPS) also experienced an 8.3% volume decline at 4.4 billion deliveries. FedEx (NYSE: FDX) delivered 3.6 billion parcels in 2025, up 5.9%. Amazon's parcel growth isn't just fueled by its own online orders, but new contracts from third parties that don't sell on the retailer's platform. 

Overall, industry volume was essentially flat (+0.4%) at 23.9 billion packages. Volumes for alternative carriers grew 13% to 2.6 billion units, highlighting a continued market shift to logistics services from online retailers like Walmart and Target, and low-cost start-ups and other independent carriers such as UniUni, Veho, Gofo, Jitsu, SpeedX, OnTrac and Better Trucks, said ShipMatrix, a provider of carrier benchmarking software for parcel shippers.
