For first time ever in 2025, Amazon delivered more packages in a single year than the U.S. Postal Service, FedEx or UPS.

According to data from logistics analytics company ShipMatrix, Amazon's logistics arm delivered an estimated 6.7 billion parcels in 2025, compared to 6.6 billion for USPS, 4.4 billion for UPS, and 3.6 billion for FedEx. Amazon's deliveries also grew by nearly 10% year-over-year, while USPS delivery volumes fell by 8.3%, and UPS saw an 8.3% dip. FedEx — which announced a partnership with Amazon in May 2025 — was the only one out of the so-called Big 3 group of parcel carriers after Amazon whose volumes increased, with the company experiencing a 5.2% bump. 

Amazon's continued dominance was fueled by a growth in its online sales, the early stages of its rural delivery program serving 4,000 communities across the U.S., and a massive scaling back of its deliveries with UPS. UPS had reached an agreement in January 2025 to slash its delivery volumes with Amazon by more than half by the end of 2026. Prior to that, Amazon accounted for as much as a quarter of UPS's U.S. package volumes, and was UPS's largest customer.

Amazon's delivery volumes have been steadily gaining ground on USPS for years, after overtaking FedEx in 2020, and UPS in 2022. This comes as USPS has faced sweeping cuts under the Trump administration, including workforce reductions, facility consolidations and service changes that have dramatically reshaped the agency’s delivery network.
